[@jedmeltonmusic698]

Will there be any fuel pressure waiting to spray me if I use this method of changing an injector? Or should I get the pressure off first.

[@FantasyCustoms4Life]

@ Jed MeltonMusic - yes if it is holding pressure like it should there will be some gas. I just throw a rag around it when opening it and that should get most of it but you could try to bleed some off the valve first I never do though.

[@johnpelley3842]

Hi great video. My problem is my 4.8 with 438,000 kilometres on runs fine when cold and you could drive to China and back like a new truck as long as you don’t shut her off. If you do, when you start her up again she runs like crap. Engine light flashing the works, rough idle, running really rich. Only trick I found to help get rid of it is to shut her down while I’m driving under load, throw her in to neutral and start her up again and drop her back down to drive. Works most times. Changed out spark plugs and new coils just recently, any ideas please

[@eileenfitz7729]

My husband had to replace an 02 sensor a couple of other things. His truck is an 05 Silverado 1500. It runs rough and there’s black smoke coming from the exhaust. Are those symptoms of a bad injector. I have an OBD computer but can’t find it right now.

[@FantasyCustoms4Life]

It’s very possible a injector is bad and stuck open, yes.

[@AmandaS-rj9zl]

Thank you for this video. I’m in a tough spot. Truck started, chugged and shut off. After some trouble shooting I randomly checked my oil. I have gas in my oil. I have a misfire on cylinder 8. (Have for years.) A mechanic friend suggested it could be my fuel injectors. Would you suggest I change? the one on 8 or all? (Going to change my oil after this mess obviously.)

[@FantasyCustoms4Life]

If you don’t wanna spend a lot of money pull the rails up and have someone crank it while you watch the injector spray patterns. Then with it sitting with pressure in the rails see if any of those injectors are leaking. Number 8 is likely your culprit but it wouldn’t surprise me that you have a few starting to fail along side it.

[@AmandaS-rj9zl]

@ I’m not sure how comfortable I feel starting this truck in my garage with how much gas is in my oil. 😂 The last time I cranked it it wouldn’t turn over. (Would they spray without a turn over?) I just got a set of 8 fuel injectors yesterday. Think I’ll just install them then change my oil and filter. Why am I so nervous about this job? Just a handy girl worried about all this fuel.

[@FantasyCustoms4Life]

@@AmandaS-rj9zlthey should not spray without turning the engine over, but they could possibly leak. If you have all 8 just replace them. When you’re finished turn the key but don’t crank it let the fuel pump pressurize the system and check for leaks before starting it. Good luck

[@mkdsk101]

Why is your check oil and ABS light on?

[@FantasyCustoms4Life]

I swapped the oil pan and someone cut the sensor wires off the oil level sensor on the new used pan. I was waiting to swap the old sensor back in when I changed my engine oil the next time (Unplugged). The ABS light was on due to one of my wheel bearings going out and the ABS sensor not reading correctly in the hub.

[@syxne7419]

[@FantasyCustoms4Life]

Wow, insane. Labor shouldn’t be more than a couple hundred at most if I were doing it for someone. Depending on oem injectors or not I’m wondering what they are charging for injectors. Crazy price in my mind I buy cheap injectors before and now just run good used and have no issues yet.

Great video. I do a lot of the exterior work to my engine. I had never done fuel injectors before. This video is straight to the point and easy to follow. Thanx!

[@jeromeeady7059]

Hello Sir. Questions to ask. I replaced all fuel injectors on my 2004 GMC Sierra 2500HD. After I checked old fuel injectors, there was nothing wrong so I go ahead and replaced. Now my OBD scanner read 2 new codes. PO107 and P0200 fuel injectors circuit open. I tried everything and still could not regain my power. Before I replaced the injectors, I had all the power and ran great like new truck. What could be the problems?

[@FantasyCustoms4Life]

I’m not sure how or why you have lost power to injector circuits. All I can think is the wires have failed to make contact or the new injectors are faulty.

[@tbenson5966]

I’m getting a P0307 code changed the spark,plug,wire and still throwing the code.

[@FantasyCustoms4Life]

You could quickly switch the cylinder 7 coil pack with another cylinders pack to see if it follows. If not next step would be popping in a new injector or trying to clean the old one. Good luck let me know how it works out, thanks.

[@tbenson5966]

FantasyCustoms4Life I changed the coil pack too. Still the same result.

[@FantasyCustoms4Life]

Check your compression on that cylinder if you haven’t already.

[@ChristianHelser999]

I have a 2002 4.8l. 100xxx every morning I start it up and it runs rough until the engine is warmed up. It throws a code p0300. Multiple missfires in cylinders. I just put new fuel pump, filter, plugs, wires. I got a better code reader and it says my vacuum is low but none of my vacuum hoses look bad. Could it be dirty injectors or what?

[@FantasyCustoms4Life]

that makes it harder to diagnose with just a p0300 code. possibly a leaking injector. Also sometimes if you have a bad fuel pressure regulator they will bleed gas through the vac line into your engine as it sits over night.

[@ChristianHelser999]

Thanks man, ill look into that

[@adrianflores7154]

You didn’t have to remove the whole fuel railing did you?

[@adrianflores7154]

So I removed the bolts from passenger side since I got the p0302 code for cylinder 2 how would I go about removing that side or would I have to loosen the other side to

[@FantasyCustoms4Life]

Hey, you can first try changing around the number 6 plug wire since that's very easy and quick. If it doesn't follow the plug wire then swap the injector on number 6 to a different cylinder. If the miss follows you can bet on it. Thanks and good luck!

How do Ik which injector to replace??

[@arcburn3364]

Good job young man. I just retired from welding, and your jacket or coverall cuffs look just like mine always did. Do you weld some? Anyway, now my hobby has become working on the grandson’s ‘99 Sierra pickup. I’m getting ready to check the injectors to stop a random misfire code from popping up. The fuel system looses pressure as soon as the key is turned off. Thanks for your video.

[@FantasyCustoms4Life]

Yes, I do weld often at my shop. These carhart jackets last about 2 or 3 years for me before they are bad like that. About be truck. If the truck is losing fuel rail pressure after being turned off look at the fuel pump, there is a one way valve that goes bad or gets stuck open causing the pressure to bleed back in the tank. Also like you are probably thinking check the injectors as well swap with some know good ones. Good luck, have fun, and enjoy your retirement! Cheers

I have a 2001 Chevy Silverado 2500hd, it’s getting about 9mpg, would new injectors help it out with mpg?

[@FantasyCustoms4Life]

@Urbex Stryder I feel your pain drving my 6.0 gas hog around and sadly the injectors likely will not help you much. Maybe it will help a mile or 2 per gallon if there is a misfire due to an injector problem. I have been told alot lately for my 6.0 to not be such a guzzler to find a good reputable tuner and he can possibly net me both extra power and MPG with a custom tune. I haven't any experience with it yet though. thanks and best of luck, cheers!

[@johnvenegas8380]

i have a 2002 chevy suburban, why does your oil pressure gauge is above the halfway mark but the message board still ask you to check the oil levels? Is it asking for more oil or is it saying you added too much?

Oil level sensor is either reading low and needs oil or is faulty. It’s on the bottom back passenger side of the oil pan. Two wires going to it.

no, this truck didnt ever make the abs kick in randomly, I do know exactly what you're talking about though cause i have owned a bunch of these trucks and had one that did. my pops truck which is a 96 started doing it too. anything from bad wheel bearing (likely) to bad abs moudule. watching the video now i have no idea what that noise was on my truck, must have been some small bumps on my dirt road that rattled something to make that noise. the abs light was on in this truck but due to it having a bad wheel bearing sensor, after the new wheel bearing the abs light went away.

alright that makes sense,i think my bearing might be going and now i just connected the dots. thanks for the reply man.

There are 8 fuel injectors, one for each cylinder.

[@GetsLAHP]

@@FantasyCustoms4Life i changed spark plugs and i still have misfire 5 . so should i replace my fuel injector on cylinder 5??

[@FantasyCustoms4Life]

l@@GetsLAHP You can first try to switch around the coil and plug wire on that cylinder with another known good cylinder to rule out a coil or plug wire problem. Also you could take a compression reading on that cylinder to make sure the inside of the motor is healthy. If that checks out then go ahead and replace the fuel injector or switch the suspect injector to another cylinder to see if the problem follows the suspect injector. Thanks

@@FantasyCustoms4Life more like removing the injector and cleaning it with b 12 cleaner ?

Oh I understand now. Yeah b12 is great! Let them soak in that and then I often hit them with compressed air or you can even go a step further and cycle them with a 12v battery and a couple leads if you want.

[@carlhowell170]

You cut the video right where I needed it... Did your fuel line pop right out of the rail easily, once you unscrewed the retaining clip? Mine appears stuck right there... Also does fuel pray all over when you pull that out?

[@FantasyCustoms4Life]

They can be stuck in there good. Pulling up with force and lightly wiggling it side to side should get it loose just try not to break it! I've had a few stuck pretty good just like you're talking about. To stop the fuel from spraying out you can press the bleeder valve in on the rail under the plastic cap to relieve the pressure. Some will still come out but it will be okay just wipe it up if you're worried prolly have a cigarette in your mouth ffs. Good luck!

[@carlhowell170]

FantasyCustoms4Life thanks for the reply. yep I found the bleeder.. it trickled a fourth of an ounce of fuel.. what is that! the whole tube still had a few ounces of fuel.. no smoking thank God.. lol I got it all sorted out.. your video helped.

i have a 2006 Sierra 2500 HD. in the last couple morning when i start it I'm getting a ticking sound on the driver's side of the motor. yesterday it happened, it studdered, the check engine light came on and i know it was only running on 7 cylinders. stopped prettt much right away. but Im thinking its an injector. thanks in advance

[@FantasyCustoms4Life]

Could be that or super common on these to have what's called lifter tick. More so on a cold morning startup. Dirty lifters that arnt working 100%. Got a new video coming out soon all about lifter ticks and when they get bad and what to do.

[@glenngreer2142]

It definitely sounds like a lifter. I'm getting ready to move 2500 miles. Have to figure this out quick.

[@FantasyCustoms4Life]

What people do to cure them varys from how dirty they are. You may be able to get away with doing a motor flush followed by an oil and filter change. What I do for a motor flush is remove about 1-3 quarts of motor oil and then add transmission fluid back in whatever you removed to get the oil level full again, then run the motor at idle for about 5 minutes and drain out and do oil and filter change and see how it sounds. Other people use kerosene instead of transmission fluid some like to use the store bought stuff which is mostly just kerosene or use mmo which is basicly trans fluid with some slippery additive. If that doesn't work then you have to go a step further removing your valve cover and using a heavy cleaning agent like sea foam or b-Chem tool and spray down the top of your push rods and let them soak, even better to remove push rods clean oil from them and then spray down them. Lastly if nothing works remove your cylinder head and replace lifter.

[@WhiskeyRiverRifleman]

You should put grease on the O-rings not gasoline

[@FantasyCustoms4Life]

When it’s handy for sure grease is the answer. In a pinch I use a tiny drop of gas or anything wet to get it to slide. It’s a tight fit especially if the o rings have swelled.

[@FantasyCustoms4Life]

That code is fuel trim balance bank 2. You very well could have a stuck injector or something faulty with your injectors possibly. Bank 2 is referring to the passenger side cylinders of the engine. To smell fuel would indicate a possible leak so be on the lookout for any fuel leaks anywhere, or a possible stuck injector supplying too much fuel could be the reason for smelling fuel as well.

This problem has been like the plague pump after pump, cleaning the tank and lines,changing the filters, rebuilding the fuel pump assembly. this is the 5th time since January! GRRR if the charcoal canister was not bleeding dust up into my tank, then the black crap has got to be coming from the return side of my fuel system right? anyone had something like this happen? when I take a plugged sock off the assembly, put it in a baggy, fill the baggy with 90% alcohol and shake it till some of the dust comes out, then dry the alcohol all that is left is super fine black dust.

+Ernie Bernal There should be fuel pressure bleeding off when you remove the line. After a second or two it should stop and only be whatever fuel is left in the top of the line with no pressure behind it anymore.

I have four misfiring cylinders have changed plugs, plug wires and the coil packs. I also have a bad o2 sensor, would it have anything to do with misfires? Or would you lean more to the injectors? Thanks

[@FantasyCustoms4Life]

o2 sensors are not going to throw anything that far out of wack in my experience. If its all 4 cylinders on one side only (bank 1 or bank 2) you might want to check for a clogged catalytic converter.

[@231MasseyFerguson]

What made you decide there was a bad injector and how did you know which one to change? Thanks for the good video. Having a misfiring problem sometimes when I take off in my '04 Silverado 1500 LS... It has 125,000 miles. Gotta take my foot off the gas and hit it again in order for the engine to smooth back out. If I don't take my foot off the gas while it's running ruff, the check engine light will blink numerous times then stay on.

[@FantasyCustoms4Life]

+231MasseyFerguson I talk in the video about the codes coming up and then reading them, it giving me the cylinder number and or a random misfire code. hearing the truck misfire as well and feeling the power loss. hoping that the obd2 gives you a cylinder number to look at you can swap coils and wires with a different cylinder to see if the problem follows. If that doesnt show then swap injectors to see if the problem follows the injector. you can also do a compression and leak down test on the culprit cylinder.

I gotta ask , you took the rail pretty much off , why wouldn't you just change all of them

Only changed the worst ones that were causing a misfire. The others were still operating well enough for the old truck so I didn’t change them. If you want to do preventative maintenance and have new injectors by all means change them all when you’re there.

[@damkayaker]

I'm impressed by the reading on your oil pressure gauge while the check engine oil light is on. My 6.0 liter oil pressure gauge reads only around 40, sometimes a bit lower stopped at a traffic light. High miles though about 225000.

@damkayaker - it’s just saying change engine oil. The pressure was fine in this truck. My 01 6.0 Silverado runs about 60 psi cruising and a little over 40 at its lowest sometimes idling. 40 is normal actually. The majority of these motors I have had run about 40 psi constant and maybe sometimes just go slightly below that but too much below 40 and something is going on.

[@damkayaker]

@@FantasyCustoms4Life - Oh I got mixed up thinking that light meant low on oil rather than time to change the oil. Thanks for the info on your experience with these 6.0 liter engines with regards to oil pressure and of course the topic of this video fuel injectors. I've got a 2003 Express 3500 cargo van and it would be a bit trickier doing the injectors. Thanks for the reply... subscribed.

[@FantasyCustoms4Life]

@@damkayaker That is whats called the "message center" It tells you anything and everything you may need to know. I have personally seen many different messages including: check engine oil level, check engine oil pressure, change engine oil, low coolant, engine overheated, Check coolant temp, battery flashing, low fuel, trans hot idle engine, trans fluid hot, engine overheated, reduced engine power, security, service 4wd, low washer fluid, and cargo lamp on. thanks man and yes try removing the dog house on that van and then best of luck! Cheers!

[@andya7283]

@@damkayaker Your not mixed up . It says change oil soon when the oil needs changed and check eng oil level when the oil is low.

[@damkayaker]

@@andya7283 - OK thanks for the clarification. I've had mine since it was new and change the oil every 3000 miles and keep thorough records of all the work I've done maintaining it. (date, mileage, part #'s, & tasks) the only thing I didn't include was a column for $$$ cost. My vehicle has a goofy oil life reset procedure. After changing the oil I have to turn the key to run, engine off, stomp on the gas pedal three times, and the oil light will blink 5 times letting me know it's reset. Only once did I forget to reset it and the light came on making me think I was low on oil. I wasn't low, the oil life thing thought enough miles went by to change it. It's a retarded reset procedure. It should be done with one of the trip odometers. A 2003 6.0 liter.

Is this the same concept as a 08 escalade 6.2l?

Yeah, it really is.

[@KTHKUHNKK]

I am not getting 302 But I am getting 174 do you think you could still be a fuel injector? Thanks Keith I just subscribed

[@FantasyCustoms4Life]

Could be a fuel injector or it could also be an air leak (intake manifold?) causing that code which is system too lean (bank 2) p0174 Thanks Keith

[@KTHKUHNKK]

Thanks for the reply buddy I have a 4.8 2000 GMC Sierra. I'm going to pull the codes again tomorrow but I have not seen a 304 or 306 yet. In the morning I smell raw gas when it's running. I got on the freeway the other day start accelerating up to 65 I noticed it was a lot of missing. I have new iridium plugs new MAF

@@KTHKUHNKK if its got raw fuel going on then you may have a stuck injector, no spark on one or more cylinders, low to no compression on one or more cylinders or possibly just a leaking fuel line.

[@KTHKUHNKK]

@@FantasyCustoms4Life I'm going to put a fuel pressure gauge on it to see what kind of fuel pressure I've got. Then I will go from there. It starts right up so I don't think it's the fuel pump. But I will check into it thank you so much for your replies. Keith Kuhn KK Motion pictures on KZbin also

Sounds like the truck is about to fall apart. Lmao.

[@FantasyCustoms4Life]

Well yeah... it’s a Chevy ;)

[@damonhaney1303]

Hey great video. Just have a question, before I go about changing this fuel injector should I first start the truck and then pull the fuse associated with the fuel injector? I have seen another similar video where they did just that but I don't want to go do something that could further hurt my truck. 2010 GMC Sierra 5.3. Thanks definitely subscribing.

[@FantasyCustoms4Life]

I have never heard of just pulling the fuse. I imagine if you only pull the fuse you will actually turn off all the fuel injectors or fuel pump or whatever the fuse feeds power to. You could however unplug the fuel injector on the cylinder you believe is the culprit without harming the truck pretty quick and easy. Unplugging a single injector will cut fuel off to that cylinder. A common way to check if a cylinder is not firing or locating a misfire on an older motor without the computer telling you where to look is I would unplug spark plug wires one at a time until you find the one that doesn’t make it start missing more (running worse and lower rpm) then you know that cylinder is not firing. So basicly if you unplug it an there is no change you know there is something wrong with that cylinder and needs diagnoses of what’s stopping it. Thanks for the question and good luck.

[@claybaby003]

Would this be the same with a 8.1 Liter 496 Eng? 2002 Chevy Silverado?

[@FantasyCustoms4Life]

its a very similar process on the 8.1. The parts are not the same though and will not interchange with ls motors such as the 5.3 and 6.0. the 8.1 is a big block chevy and not in the ls engine family.

[@JLE1177]

Great vid, my van looks diff but same concept

[@FantasyCustoms4Life]

@Jeremy L - if it’s 99-07 it’s all the same you’re just doing it from inside the dog house on the van. Anything newer it’s the same process just the parts look sightly different. Best of luck 👍

[@JLE1177]

@@FantasyCustoms4Life I’ve pulled the fuel pimp relay, cranked and, undid bat, and injector wires but when pulled the injector rail fuel started pouring out, what did I miss? Also had the gas cap removed and pushed that shader valve..

[@JLE1177]

@@FantasyCustoms4Life I’m working on a 2020 Chevy van 3500

[@FantasyCustoms4Life]

@ Jeremy L - there’s going to be gas in those lines when you remove them. The injectors will fire under pressure but will not remove all the fuel from the lines. You may have bled off the fuel pressure from unplugging the relay and cranking/touching the shrader valve but there’s still a volume of fuel in the lines thats not going to move anywhere until the line is undone to leak out. If it keeps pouring out fuel and will not stop then you likely would have a fuel pump/check valve problem. Yes the 2020 is going to look somewhat different than this 99-07 style but it’s basicly the same process like I said. Thanks

Can i clean the fuel Injector

[@FantasyCustoms4Life]

I don’t see why not?

[@walleye892]

I got an 04 silverado 5.3L and its got a p0300 reading. It seems to skip around 1500 rpms at around 45-55mph in a slight incline but the check engine only comes on once in awhile while its doing it and then shuts off farely quickly. Been getting worse and have poor gas milage. Cannot seem to pinpoint the problem changed the wires and plugs but found it weird that it only does it around that rpm and speed. Was wondering if you ever expiernced or heard of such a thing. The video was very informative alwasy trying to learn new stuff to avoid the labor bills

[@FantasyCustoms4Life]

hard to pinpoint then but you can try things like check out your fuel pressure regulator, replace coils and spark plugs, and pull the injectors to see if they are clean or dirty. if any of the injectors are really dirty then replace that injector.

[@marvinmacon9673]

walleye892 p

[@dustinserbin3054]

Have you tried new cats? They make aftermarket replacements, I have the same code, and that is the last thing I am going to try. I plan on new fuel injectors, then cut the old cats out and put in some universal magnaflows.

[@sbond1963]

why clear the error code? don't you want it to clear up by itself to know that was the fix and not plugs or an O2 sensor??

[@FantasyCustoms4Life]

+Bondo I've never heard of a o2 sensor causing a cylinder not to fire completely also, I had already put new plugs in. For video purpose I didnt have the time to drive around waiting for the light to go off. Its faster to clear the code and watch it not pop back on a minute after starting the truck. Someone less experienced may want to let the code clear on its own.

FantasyCustoms4Life no problem and real quick question! I just took my 97 GMC pickup truck to the mechanic and he said he fixed it but now he said there's black smoke coming out from the exhaust. And he said he's going to change a sensor and I have no clue what's he talking about? Is that normal?

[@FantasyCustoms4Life]

If it wasn't happening before he worked on it I would think he messed something up. What did you bring it in for to begin with? What sensor is he trying to change. I would be worried if I were you that does not sound normal.

hey great video. simple quick and easy.

[@joshp2435]

hey man, I have a 06 2800 that's showing p0300 and p0171. Is it safe to assume it's a fuel injector? To my knowledge it came on after I changed the plugs.

[@FantasyCustoms4Life]

I would say that's a good place to start would be looking at bank 1 fuel injectors. What kind of plugs did you install?

[@robertsarabia2828]

What about the driver side? You know, the hard side.

Hard side? Not really... One extra o-ring on the fuel line of the fuel rail compared to the other side and unbolt the line coming up from the tank and that's really the only difference, but yeah sure its the "hard" side lol.

Thank you

[@SECRETGOVERMENT2012]

Or just pull the injector plugs till u find the bad injectors

That actually doesn't work as well as you might think unless the cylinder is completely dead. Even then the codes read me the cylinder misfiring and is much easier and faster and more accurate.
