How To Replace Crankshaft Position Sensor on a 2004 Chevy Silverado we bought at Copart

[@christianheathington4973]

Thanks man, this really helped me understand what's going on with my truck. Keep making these informative videos

[@zsproshop]

Thanks for the support glad I could help

[@ntgreat5]

So how'd ya get it to run. I have spark an fuel pressure an all it does is crank an crank.

[@cyclonus01]

You kind of didnt gjve the full picture at the end. Did you actually clean off all the grounds before reolacing the cluster?

[@isrealcruz7555]

Hey there!! I’m having the same exact issue with the same exact vehicle. I was wondering if you cleaned the grounds and that fixed it? I was unsure what you ended up doing to make it run. If you could let me know I’d really appreciate it. Thanks!

[@x1lightningman725]

Did you ever get an answer? I'm in the same spot you are. Did the cluster fix the truck not running? Help! please!

[@x1lightningman725]

To isrealcruz7555(I'm sure figured it out by now) and anyone else having the Crank, No Start issue. I figured mine out. Apparently, it is a common failure. I was very close to replacing the fuel pump. But I'm glad my head overrode that. I purchased a fuel pressure guage and found there was no problem with the pump at all. I may replace it anyway. It's a 20 year old truck with 210k miles. Why wait for it to fail? But I digress... I tested for spark(where I should have started before the $150 tow bill😢). No spark!! This was due to no ground to engine harness for coils(possibly other things too). I grounded one of the coils and it started right up. That ground is shared. The ground wire in question is located on drivers side of the block just behind the PS pump. It's labeled in a diagram I saw as G102 or ground location 102. Anyway, I couldn't see the location of the eyelet from underneath. But I did locate a single loomed, small guage wire going in that direction. From underneath, I gave it a little tug and with very little resistance it came right out. I'm glad that was the right one. 😅 I extended it with a new eyelet and ran it up to the accessory drive bracket in the lower of the two bolts that hold the power junction bracket on. That's the red plastic box at the driver's side front of the engine, just above the PS pump. All is good now! I believe this will pretty much last forever! 😊

[@efrainbustos4053]

Did the cluster was the problem of not getting ground on the injectors? Did hear how you got it to start after you checked it with the probe, would appreciate if you can share the information, thanks

[@tommygunn3731]

What was making it not start?

[@wongway40]

Thanks for the video post, Im guessing the only problem was the broken middle wire of the crank angle sensor plug? Maybe the old crank angle sensor and jump start battery pack may have been ok. It would be interesting to see if it would start with the old sensor, and battery jump start pack to isolate the problem

[@claytonshields9972]

Hey I put a new one in on my 2001 4.8 GMC Silverado I think the new 1 It's not letting me start it on the 1st turn or maybe I could have bad wiring sports plugs or essentials or centuries please let me know thank you my friend you helped me put my car together

Whats up guys I have a 2005 chevy silverado v8 I change the cps and still doesn't start please help me. Thank you and happy new year

[@roltyd22]

You didn't have to do a relearn process when you changed the crankshaft sensor?

[@zsproshop]

On this year I did not have to do a crank relearn on some of the newer ones you will have to usually big headlights body

[@roltyd22]

@@zsproshop I have an 03 Tahoe so i shouldn't have to do one? I think mines leaking oil from the o ring

[@zsproshop]

@@roltyd22 probably will not have to do a relearn process if it is just leaking could always just replace the o-ring and use the same sensor

[@cenmike82]

Put metal conduit on wire lead did this never had change wire again they burn with starter heat on start

[@BillaBong1]

So is the cluster plug and play? I thought when you change cluster u have to do something to the ecu/pcm so they will work right with each other. Like have your actual milage on the replacement cluster. Well thats what i was told. Can i do this too? My speedometer is not working and dont have money for the shop to do it.

[@threadtapwhisperer5136]

You can disassemble the clustee to swap out the stepper motors. There are some people that do entire refreshes on these GM gauge clusters. I know that GM is friggin proud of that cluster. They are nearly $600 new, LKQ sold me two of these clusters and it was $65? I wanna say? One somewhat major issue would be not knowing how to solder. You would need to de-solder and clean the9

[@John_D2]

Will that sensor cause a misfire if it's bad ? Thanks

[@zsproshop]

Most the time if this sensor is bad vehicle will not start

[@John_D2]

@@zsproshop ok thanks for the reply.

[@jeffhooker7316]

John d. You have a cylinder 6 misfire? I’m asking because I’m having a problem figuring out my cylinder 6 misfire. New plugs,coils,injectors,wire’s, new fuel pump, egr, o2 sensors. Light blinks at idle only! Drives great has power I have been fighting this issue for a long time. Thinking maybe cps but I doubt that’s the problem. Just recently it has not started right away. But it does fire after I give it gas! It has a new filter also.

[@John_D2]

@@jeffhooker7316 mine ended up being two bad coils , one went bad right after the other one..lesson learned , don't buy cheap coils from rockauto. buy them some place like autozone with a lifetime warranty.

Is the the 5.3, 4.8, or a 4.3?

5.3 4.8 same same lol

[@tjdjinn1983]

@@zsproshop there's differences between the two. I didn't know if the sensors are different or not.

[@stubaker1737]

On the cluster, it's usually a bad solder connection, easy fix. Always check your stuff first, it would probably have saved you 2 trips to the boneyard and changed the title of your video.

[@zsproshop]

thanks for the reply

[@timmybangs4711]

So far my truck has proper fuel pressure 55 psi mainting for over 4 hours Brand new spark plugs Brand new spark plug cables Brand new distributor cap Put a new ignition switch on Is there anything else i should look into to fix my crank but no start no spark problem?

[@zsproshop]

Kind of mentioned in the video easy way to tell is if you crank the engine and get no RPM movement on your cluster

[@feltonjonesjr1830]

Upgrade your engine grounds n clean area with wire brush. I have 04 suburban same issues. Not anymore 🙏

[@timmybangs4711]

Long story short. My 2004 chevy Silverado wasnt starting. Install a new ignition coil and ignition module. Truck now starts and runs great. But the check engine light came on with code p0351. Cant seem to find the problem. Any pointers? Anyone knows what it could be? Truck runs fine and doesnt have any issues starting up or rough idle etc.

[@danielarney9729]

How did you initially know it was the cps?

[@zsproshop]

Sorry was not able to show the diagnostic procedure but I was able to scan it before the video and had codes for crank sensor

[@chachifeere]

why would you get a used sensor when you need to pull the starter . alot of work to use a used part

[@diggindiggenit6540]

What a FK up place to put a CPS dang, maybe that's what I need to replace, NC & NS situation but I can start the chevy off the starting relay pin 87 to the positive battery terminal, I have the 10 amp crank fuse light up when I turn the key on. The only hot wire on the starting relay pin 30, it stays hot regardless, but none of the other pins go hot when I turn the Ignition switch, can't seem to find the wiring diagrams on line so not sure whats wrong?

Go on Amazon and order the ignition coil harness, it's around $30-$40 bucks... I've had to do that on a few of my customers vehicles... Sometimes there are breaks inside the insulation that can cause a weak connection...

So it was the cluster?

[@mikemasten3252]

So was it a ground that was making the injectors not fire? What was causing the injectors to not fire? If it was a ground, which ground wire was it and its location. Im having the same issue with my 2006 cranks no start but starts with starting fluid and dies. I am changing the CPS now but if it doesn't pulse the injectors after then I need to know if it was the grounds.

[@beeswax2182]

Hey did it work for you? I got the same problem

[@timmybangs4711]

Hey guys i have a similar issue. It crank but not start and no spark. No spark in the spark plugs. Cant seem to find a decent youtube video on how to test the ignition module and ignition coil. I guess i will be moving on to the crank position sensor and maybe that fixes it for me

[@beeswax2182]

@@timmybangs4711 I fixed the issue guys. It was the ground wire for the coil harness going into the coils!!! 1. Check for the ignition coil harness on each side of engine. There are 2 in total. 2. Disconnect HARNESS and check all terminal openings , you will see terminal openings for pink and black wire and others but only care about the pink and black. Check the black one (negative ground) with test light, if you do not ight up then the ground for your coils have broke...the ground it runs off is the same as main battery ground so you can trace it back if you want....I didnt I just installed new ground on the black wires in each harness. Took me under an hour and 2 buck fix!!!!

@@timmybangs4711 before u do crank sensor dont......do the harness ground it was super cheap and easy to check. I did the sensor as well and it was over 100$ plus time to get relearn...was b.s when I found out it was the frickin harness

Expert piano HQ Piano Im not to sure what you are talking about. I have a 4.3 v6 chevy silverado with distributor cap. Yesterday i check to make sure the ignition module and the ignition coil are both grounded properly.

You spent all that time getting an $8 sensor from the junkyard?

[@zsproshop]

Yes $8 at the junkyard $75 if you buy a new I think it was worth the extra 15 minutes to drive to the wrecking yard

[@pantherplatform]

@@zsproshop I suppose it depends on the circumstances. After what I went thru yesterday to replace the crank and cam sensors on a 2000 5.3, it was nice to just pull the new ones out of the box. There isn't a salvage yard around here for miles either. Turns out the #7 spark plug was shorting out on the metal sleeve that goes over the boot. Looked like the plug had a black lightning bolt on it. Put a good used one in there and she hauled ass. It definitely needed those sensors tho...
