No Start No Fuel Pressure Troubleshooting - GM 2.2 Ecotec

[@FOCUS-777]

So true Paul. knowing your tool and its procedures is as valuable as Knowing the circuit your working on. I fried my dvom by simply didn't switch to voltage setting but left it on ohm setting while checking a high voltage system.

[@saneauto]

Im working on a Saturn Vue. Was 90% sure the fuel pump is bad. Im glad I kept watching till the end, I had forgot to bang on the tank. Duh Im gonna have to drink more coffee. Getting forgetful in my old age. Thanks Paul

[@DJDevon3]

Issue is obviously at the pump somewhere. Another successful diagnostic video. Thank you for making videos. You're amazing to learn from..

[@ScannerDanner]

Thank you!

[@rusco321]

Your vocabulary is absolutely exemplary. Keep up the good work.

[@ScannerDanner]

That's a first. Do you mean how I speak or that I try not to swear? It's funny how much recording and editing myself has caused me to speak differently. Eliminating verbal crutches and slang words etc. And of course I try to not speak coarsely too. No need for that. If only I could control my tongue better off camera :)

[@SchrodingersBox]

Rusco may have been first to comment but not only one to notice, your vocabulary and fluid speech is one of your best assets that you naturally display without trying and it is one of the main reasons that I can watch your videos from start to finish every time. Videos with 200 "Um" and "uh"s are just unwatchable, you seldom do that. But also you just naturally spit out phrases like "I really need to validate this test with a positive control" showing not only logical if not scientific thinking but also use of proper nomenclature for the action itself- I would not expect many mechanics to know what a "control" is much less a positive or negative one. Had you been a medical researcher you would be curing cancer as well as you fix cars, the process is absolutely identical- forming a hypothesis to explain an observation and testing ONE variable at a time in order to support the hypothesis to the point where no other explanation can be possible but for one variable that you can reproducibly show causes the problem. Whether it's a bad ground for a fuel pump or a mutated protein causing an immune system failure, the process of finding the cause of either problem is absolutely identical.

[@ScannerDanner]

Schrodingers Box wow, thanks bro. I really appreciate your comment. If you watch some of my earlier videos, I have a lot more "Ums" in them. Funny how much hearing yourself and editing out those forces you to change your speech. Any good videos you've done lately? Send me a link to one you think is top notch.

[@SchrodingersBox]

I think this one would be right up your alley brother- in fact i bet it stumps even you! Diagnosis of Intermittent Hesitation, Skip, or Miss 2000 Trans Am- PART 1

[@12vgs8606]

Schrodingers Box Matt put it brilliantly! But there are very few Matts or Pauls running their own shop or using the wrenching to put the food on the table. These type of guys are too smart to get stuck in a auto mechanic career. Matt is a scientist and Paul is a lecturer. Of course there are few professional mechanics on the youtube with similar capability but most shops don't have these kind of people working there :-(

hey guys; every little bit helps thanks to those that share their knowledge Free of charge. amps is my weakness, I appreciate everything I can get. El Jefe Automotive. Waco, Texas

[@scrimmy6969]

Thank you sir for everything you do. You open my eyes to different ways every time I watch your videos. Thank you again Jim

[@ScannerDanner]

cool man, thanks for being a great student!

[@scrimmy6969]

ScannerDanner Thank you for being a great teacher

[@ksarrow]

Thank you so much for your in depth explanation of how to tap into circuits and test,

[@CesarPerez-ck7ci]

Paul, I would like to see you do a video of your full day, I dont mind not getting too much info about the work itself but maybe like "A day in pauls life" maybe it would be cool to see how your life goes on at the shop. something different just for one video would be cool.

[@jarinwilson9539]

Pony-ack...There's that PA accent, sorry I had to Paul, lol. I was literally bobbing my head up and down throughout the duration of this video. Awesome job.

[@jheetman]

soooo love how he first looks for what he doesn't have

[@dmorley100]

Haven't used the UActivate tool, but love diagnosing bad fuel pumps using the amp clamp. Lord knows I've nailed bad fuel pumps on Mercury Grand Marquis and Crown Victorias in like 3 minutes with the amp clamp.

[@glen-ozzstarscars8474]

Great diagnosis! The Fonzy touch on the fuel tank........it works, happy days! lol

[@tonysorensen421]

Is it possible to ohm out the fuel pump windings from the relay port. I know this would necessarily tell you if the pump was bad but could it show that the wiring from the relay to the pump is good, thanks.

[@johnknox5692]

thk for the vidieo i liked the aes tool, made the diagnosis of the fuel pump circuit a lot faster than normal processes> old school.

[@philbfree1]

did you ever get the relay adapters? there adapters you plug in to were the relays go then you plug the relay into that? they woulda been nice here to

[@luismartinez4198]

how about using the power probe hook. take out the relay and test everything from there. It can take you to the right direction. there is even a video on power probe website, of how to do it. There are always different ways to test components, so its worth sharing the different approaches

[@jonathanlessard5517]

i love your channel Paul keep on going man !

[@Viper81766]

Great video brother. When did they change the color of your uniforms? And to Ford blue haha. Picking brother. Awesome teachings.

[@powayflores13]

i have that tool its a good tool had to get it once i saw you use it on that cron vic. with the fuel pressure problem.

[@karennavarro567]

Paul,nice job showing us testing and thought processes , You are a very hard worker,If you had to check for spark or defective ICM on this what will be your preferred or best method I had one of this with rondom misfire ones had new oem plugs already. but this unit on top of the valve cover is very expensive and I did not find the proper way to test it thanks god bless you. Some thing call my attention I was looking at the wiring diagram on this vehicle you are working on the ICM connector on pin F from coming from PCM is label CMP sens sig, but the vehicle does not have cam sensor ?

[@thaison9892]

You can try Relay Buddy tool, super quick and fast to check out most common relays :)

[@gvvq-pi5ml]

Hi Paul, did you look to see if there was any fuel in the tank to start with, sort of thing I would get caught on, good video again, well done.....Fred UK.

[@ScannerDanner]

for sure, I've been burned by that before too. In this case, an empty tank would not have caused an open in the brush contacts of the pump unless the pump burned up from the lack of fuel (I've seen this many times). So either way it is still getting a pump.

[@ginopunsalan]

My 1991 Galant takes a few seconds to start after cranking. Any advice on how I should go about this?

[@SteveRobReviews]

We'll done Paul - I think we need a tutorial on the uactivate. LOL

[@killman1971]

My sister's 04 Pontiac Grand Am with the same 2.2L Ecotec has a weird problem that I can not figure out. This problem started back in January during that wonderful past winter. About once a month or so it will not start with no fuel pressure with initial key on or cranking. Simply put tapping on the relay seems to get the fuel pressure back again. I have swapped relays as well as bought a new relay and the problem still persist. The relay contacts seem fine (not burnt) and I even have dropped the fuel tank and checked the fuel pump connector which is fine (ie no arcing damage which can occur on these fuel pump connectors). The only problem that I can see is that the plastic case near the +12 fuel pump supply connector on the relay was a bit discolored (tan) like it been running warm but all the electrical connectors seem fine. Previously the original factory fuel pump went bad 2 years ago which I diagnosed and replaced. Does anyone have any clue as to how to go about diagnosing and fixing this problem? The worst bit is it is so intermittent I can not figure it out.

[@ScannerDanner]

Voltage checks at the relay during the no fuel psi problem is the only way. You do not know if your problem is on the control side or load side of the circuit yet. And without knowing that, there is no reason to debate what it could be. Make sense?

[@DennisFriedman]

ScannerDanner Thank You Dennis

[@alejandroamaro8303]

Hi Paul. would you recommend the OTC 6550Pro fuel pressure test kit ? im thinking about buying it.

[@ScannerDanner]

+Alejandro Amaro any professional fuel psi kit is a must have tool. We have that same kit at our school, so yes it is a good kit and will handle most of your cars

[@alejandroamaro8303]

+ScannerDanner oh. okay Thanks. ill look into buying it although it is a bit expensive, but it'l pay for itself in the long run lol

[@TexasPLNR]

I've found that "hammering" the fuel pump w/ repeated on/off/on... will start a balky pump also. regards

[@StreetBikeTakeoverYT]

What shop do you own or work for? I've been having issues with my car for over a year and nobody can figure it out..is there anyway you would be able to diagnose what's going on with my vehicle? I'll make the trip just to find out.

[@johngamache7]

Hey! i have a 2005 lexus es330 i recently changed the fuel filter "in the tank" and sock i pulled the fuse and battery cable toke the fuel hose off pump "had pressure still with alot of fuel spraying out" put the new filter and sock on "wich were after market " put the battery and fuse in and now the car wont trun over the pump is new and works i can here fuel go threw the line but when i take the fuel ine off theres no fuel pressure any ideas?

[@adaptine]

I quite enjoy your movies, even tho I'm an electrician working with ships and stuff. How much dyu charge the garages for troubleshooting?

[@ScannerDanner]

It has changed over the years as my business has grown. Right now I am charging $70 for the initial hour. (5 minutes or 60 minutes) Every time I have raised my rates, with the hope that some of the shops would stop calling me, I've never lost one customer. I've dropped most of the shops now as these videos are so time consuming. I went from 20 at it's peak down to about 3 right now. These 3 garages feed me enough work to keep these case studies going, to keep me sharp, and to help me teach my class more effectively.

[@hualiao9847]

Great video as always. If I could get your thoughts on this case, try to pass CA smog on a 98 sable. Car fail HC and CO at 100 and .6, NOX is very low. If I pinch off fuel pressure regulator vacuum hose, HC and CO drops to 20 and .1 which is pass. All readings are under load at 15mph on dyno. LFT is 3%-6%, STF 0% to -4% which I think is OK. O2s switching good. Any thoughts are appreciated.

[@pauldanenberg7746]

I know this is an older video so you might not reply, but did it turn out to be the pump? You said the tool was indicating an open in the circuit so I'm a little confused.

[@Chewie2254]

Paul Danenberg Yep sure is the pump. I don't know the proper terminology to explain it, but the circuit was open inside the pump, and when he beat on the tank the pump spun just a little bit and made contact again. The car will run fine until you shut it off and the pump happens to stop in the deadspot again, then you'll have to beat on it to try to get it going.

[@Mikeyddread]

you is a genius man

[@sammyreliford6898]

Scanner Dan what causes a trailblazer to blow the a fuse time you try to crank it up it blows the ECG fuse I think that's the right one but some say its the oil pressure switch and son say its the fuel pump can you help me out thanks

[@ScannerDannerPremium]

Post this to my forum. We can exchange information better there. I'll need the exact name and or number fuse and which fuse box it's in (under hood or in dash) www.scannerdanner.com

[@sammyreliford6898]

Its the ecm1 fuse under the hood

[@notsure3331]

for the fuel pressure regulator cos jerking and RPM fluctuation while driving and idling wondering I got that issue and can't figure it out

[@petrocksgarage]

I like the idea of that tool. Probably makes playing with relays a lot easier. It looks simple enough I’ve been thinking of building one myself since I saw it in one of your other videos but haven’t gotten around too it yet (too many other projects at the moment). The built in polarity tester is a cool feature. It probably uses the two LED’s with both cathodes & ground attached to each other in a T. Current can only flow one way, so only one LED will light up indicating direction. Pretty cool feature.

[@ScannerDanner]

It is cool, I'll have to check the tool directions. If it lights up red or green, I don't know if this tells you the pump side or the feed side of the circuit. I think feed side?

[@drbsr1948]

Nice video Paul, I went to the AESwave site to look at the uactivate tool. They must have changed the label design on that tool. Where your switch indicates LED, it now shows M-on. Apparently you have to hold down the switch in the momentary position which is LED on your tool correct? The on-off position toggles and stays in either until you change it correct? Check it out.

[@ScannerDanner]

Yes, the LED position is momentary and was not designed to activate the circuit (although I believe it will) but to tell you circuit polarity. The on/off switch will stay in that position. I talked with the designer yesterday and he didn't mention the M change up on the tool so my guess is the internal design is no different. Thanks Danny

[@drbsr1948]

ScannerDanner OK..on the M change, I think if I were the designer of this tool, I would have just called it what its indicating : polarity...... rather that the function of the switch. The power probe tool in comparison has the LED's. If the green one lights it indicates ground side (-) polarity and if red one lights it indicates Positive (+) polarity. My guess is there must have been some confusion and that's why there was a change from LED to M-on. I think for the tool he was on the right thought path with LED....but polarity would have been more clear.IMOO? I think it's a cool tool but a little over priced...just my opinion not knocking the tool or the designer :o)

[@steverogers7781]

I have a 2003 2.2 eco-tech Grand Am crank no start as well. I changed the fuel pump and fuel filter still crank, no start. I changed ignition coil and boots and plugs and ignition coil module. Same. No fuel at Schrader valve just by checking with screwdriver. Switched out, relays for fuel pump same, and all other fuses are good. I am a super novelist beginner, so not sure where to go from here. Any help would be appreciated

[@steverogers7781]

I’ve also tried the security pass lock bypass with the key on for 10 minutes. My security light stays solid red, it does not blink. Won’t start with starting fluid either.

[@ScannerDanner]

with the key on, do you have 5v on one of your TPS or MAP sensor wires?

[@steverogers7781]

@ I haven’t had a chance yet, but wow that is awesome. I was not expecting you to respond. i’ll keep you posted after the holidays. Merry Christmas buddy.

[@ScannerDanner]

​@steverogers7781 merry Christmas! Just reply here with that test result

cyclopital3d sells polarizers for camcorders to filter out glare, or maybe your brand camcorder sells a polarized lens

[@onsitetechnologies9298]

I have a 2006 Chevy Malibu with no fuel pressure at the fuel rail. I replaced the fuel pump and I hear it run, but no pressure at the rail. I can disconnect the fuel line at the back of the car and it will spray fuel. I go to the front and disconnect the hose going to the fuel rail and it stops there. (Fuel comes out of hose from tank) Do I have a bad fuel pressure regulator? Will that keep the fuel from going to the fuel rail? ( The car will start with start with fuel or starting fluid.) Note: When this started I drove to the store and when I came out it would not start.

[@onsitetechnologies9298]

new fuel pump but it was bad. got another and ran fine

sorry to post twice I was sign in with my Daughter you tube account previous. Paul,nice job showing us testing and thought processes , You are a very hard worker,If you had to check for spark or defective ICM on this what will be your preferred or best method I had one of this with rondom misfire ones had new oem plugs already. but this unit on top of the valve cover is very expensive and I did not find the proper way to test it thanks god bless you. Some thing call my attention I was looking at the wiring diagram on this vehicle you are working on the ICM connector on pin F from coming from PCM is label CMP sens sig, but the vehicle does not have cam sensor ? sorry to post twice I was sign in with my Daughter you tube account previous.

[@ScannerDanner]

That is a cam signal that the ICM generates based on the firing KV of the #1 or #4 cylinder (can't remember). It is called a synthesized cam signal. This is why a bad plug or wire will give you a cam sensor trouble code on this design.

[@JoelAutomotiveInaction]

ScannerDanner thanks for answering quick, How would you test this ICM? with low amp probe?

[@ScannerDanner]

Joel N the control signals can be verified with the scope using a voltage trace. the coil primary can be monitored with an amp clamp. Also the secondary can be played around with if you remove the housing and run plug wires between the plugs and the housing. I used to do this all the time on the GM 2.3, 2.4 "Quad 4" engines.

[@JoelAutomotiveInaction]

Thank you I did think that but is good idea.

[@TechBen19]

hi, sir danner, if you have a chance to post a video, in nissan vehicle or infiniti, that the rpm fluctuates, please make that video of how to address that problem, thank you and god bless :)

[@WRMonger1]

This was absolutely useless for me. I had a fuel pump that worked and put it in with the same results, no fuel pressure. Could it be the relay? I checked the fuses

[@ScannerDanner]

What was FP power and ground when measured directly at the pump connector during cranking? (Loaded circuit)

No disrespect to your client Paul, but if I am going to have my own shop, this is something that I expect to be able to fix it myself without having to call in the big gun like you for this particular problem! What do others feel? I expect a typical mechanic to be able to figure this out without much trouble at all. In a nutshell, why was Paul called to solve this "trivial" problem? Has the quality of typical automotive shop has dropped so low that even the run of the mill problems now need the best brain in the country to be employed to solve it?

[@Viper81766]

Men with Pauls expertise and time in this field are hard to come by and the average mechanic does not specialize in this electrical/performance area as Danner does. Great mechanic and awesome teacher.

[@moshe2002]

and that shop had to get you for this kind of problem ? mmmm....... bad they need someone like you permanently (don't tell them that i say that)

[@petrocksgarage]

From what I gather, Paul is more of a Nomad / Casanova style mechanic. He works where & when he wants to. The shops don’t pay him to stay, they pay him to leave. Wham, Bam, Thank You Paul. ;-) With how quickly he works, a single shop wouldn’t have enough diagnostic work for him to do to keep him busy. They would end up paying him mostly to sit around twiddling his thumbs most of the day & building mad skills on Angry Birds. Its cheaper for the shop to hire him by the hour, and as an added bonus Paul gets to charge the shop more for his time. Its a win / win for both sides.

[@ScannerDanner]

No, they could have handled this one. They typically do not even look at them before calling me. They are a busy shop and this set up works best for everyone. For me, sometimes it's an easy one like this, sometimes it is not. The shops do not care, they mark up my fee and do the repair. No worries about replacing something that wasn't needed from the garage side. So they sell the job with confidence to the customer. Everyone is happy!

[@ScannerDanner]

Pet Rock's Garage well put my friend. And my first hour fee is the same if the job takes me 2 minutes or 60. So you guys can see why I want to find the problem as quickly as I can without sacrificing accuracy. This is the core of everything I do. Of course a lot of my videos, I am teaching methods so it can take longer in those circumstances but once you learn and apply the method your flying!

[@drbsr1948]

ScannerDanner So Paul.Your minimum charge is and hour and I believe I read on one of your other post that you try to not take over 2 hours on any one car , correct?

[@ScannerDanner]

Danny Berry That is correct Berry and I rarely go into that second hour. My track record is it will take me 20 minutes or 4 hours :) There seems to be no middle ground.
