Diagnosing Silverado Fuel Pump Control Module

[@sammattei720]

Thanks for the video man! I jumped the FPCM as you did but my pump did not kick on. Left the jumper wires in and wiggled the connecter on the actual fuel pump and it finally kicked on. Turns out I just had a loose wire. Thanks again!

[@kevinthompson3794]

I had a no start today and had my truck towed home. I scanned and got a U0190 code. I was thinking it was the FSCM, but after watching your video I went out to check the fuse and sure enough it was hard and broken and I had to break into pieces to get it out. I put a new fuse and truck runs great. You saved me hundreds in parts and programming. Thank you.

[@visionarybrushstroker7694]

Fuel pump fuse?

[@shanefus64]

Finally someone that keeps to the point and explains every important detail without wasting a lot of time on bullshit. I'm a master mechanic and your the first time I liked and subscribed to a fix it video. I'll be sure to look you up in the future.

[@CumminsTech24]

If your a master mechanic you wouldn’t be on KZbin for a tutorial

[@NutsandBoltswithTone]

great video, I love that you showed the wiring diagram and explained how to trace it out, and understanding it. Wiring diagrams are so important to be able to read and there are alot of newer techs that just cannot do it. The code checking thing was funny, I think the same thing when I see people ask that question without scanning for codes.

[@miciahk]

If you buy a Dorman Control Module, it comes preprogrammed and doesn't require any other programming. It is a plug and go module. Only Dorman.

[@alanwylie8960]

That's kinda like the Ford OEM baling wire. 😂

[@gustavofermin168]

Thank you for this... mine was throwing me off because I was putting the test light on the top contacts to the fuse and they were both lighting up. I checked the contacts at the connector to the module and I was getting no power. I ended up removing the fuse and it was burnt at the bottom leg. Now let's just hope the fuse doesn't keep burning out... This video really helped.

[@reaganwarren7975]

Man this helped me so much. i got a 2019 that threw this code and had no clue how to repair until i watched this

[@reaganwarren7975]

Also what exhaust tip is that?

[@Dw1067]

Best video yet on diagnosing a gm fuel module. Great job brother 👍😎

[@imjeremy51]

Fom what I understand the fuel pump is Pulse Width Modulated, meaning the speed of the motor is controlled py a pulse sent by the FPCM. It doesn't run off of straight DC voltage. The point of the FPCM is to regulate the fuel pressure by reading the pressure sensor and adjusting the speed of the pump. Thats how they don't have a return line from the fuel rail and a pressure regulator.

[@davidhall3747]

Pulse Width Modulation. (i.e) Duty Cycle.

[@shanefus64]

Oh one more thing. I work alone in my shop also. Remember the old plastic door buzzers mounted under the dash? I put 2 pig tales to it and use it for all kinds of power and ground testing in the back. no long cords and a test light, just listen.

[@Roybwatchin]

I like it. Thanks

[@joshcollette3612]

Great video! Had the same issue all crank no start ended up just being a blown fuse! Thanks again!

[@pedritoc.c.t.665]

I have been looking at how to drain my fuel tank by activating the fuel pump bypass. Since mine doesn't have a simple relay and you showed how to activate the fuel pump clearly and can remove the bad gas I have in my tank. Thank you.

[@jorgeb4963]

Great video.. i have 2018 Sierra, same problem. In the cold no chance of starting. Towed in to dealer replaced fuel pump control module on Wed, today is Sat.. same problem all over! Check engine light back on gas gauge stays on Empty! Warm weather comes and it starts up and check engine light goes away and gas gauge is normal again.. then it occurs when it wants to! Bought truck new has 23k miles .. so frustrating! At a loss. That part should not even be there to begin with.. easily can get wet and damages.. last GM truck for me!

Thats whats great about all my old wore out trucks , no diagnoses needed , just replace it all , 338,000 miles , im betting it needs it anyway 😂😂 I had to watch this again after i asked a mechanic at the gm dealer if there was a fuel pump module right were your at , he said nope 😂😂

[@testdepth377]

Thank you! This allowed me to drain a 2012 Yukon Denali 6.2L 26 gallon tank so I can drop the tank empty instead of full. When do things break? Right after you filled the tank of course! BTW the key does not have to be on or in the ignition.

[@ryancornelius1007]

Quick question, you can just bring the part to the dealer and get it programed that way? I found a company here on youtube that will sell you one flashed with your vin. Pretty sure mine is bad its been feeling like i had a misfire so i figured i needed a tune up but then my check engine light came on.

[@TheDieseldog]

I had to have it on the truck when I had it programmed at the dealer.

[@TheDieseldog]

If you have a misfire I doubt this is your issue though

[@ryancornelius1007]

Just feels like a misfire but isnt throwing a code for it. Just has that hesitation sometimes and last time i pulled my camper it didnt have shit for power. I really gotta get to the bottom of it.

[@FishnDeer]

P0191 CeL code. High pressure rail sensor A, replaced it on the rail. Replaced the low pressure sensor on frame below driver door. Still same CeL code. Ordered a fuel pump control module from oreillys. Wonder if I need to program it? How do you know if it’s plug and play or not??

[@smith85ish]

[@davidjohnstone1860]

Vice grips from the bottom of the bolt you only need to turn it twice then you can slide it out 🤙

[@enthused7591]

I just replaced my fuel pump and crank position sensor, shortly afterward it would stall and read "no fuel". Swapped my old, functioning OEM pump back in, still does the same thing where it'll intermittently run for a few minutes perfectly, show correct fuel level, then stall and show no fuel. Cleaned all my grounds as well. Are those similar symptoms to what you had? Mine's an '04 and I didn't even know there was such thing as a fuel system control module. Only getting P0420 catalyst inefficiency code which has been on for 4 years.

[@TheDieseldog]

04 will not have the control module. I would check the fuel pump relay. Probably need to get into checking power and ground to pump when it dies and won’t start.

[@TurboTyTy]

[@alanwylie8960]

Yep, these big auto manufuckturers deliberately design their modules so that you have to bring your vehicle in to get their overpriced modules reprogrammed so that they can extort more of your hard earned money.

[@oscarlandag1831]

Oem zip ties that’s hilarious I’m gonna use that🤣

[@deezy7811]

So if I’m getting that same code and my truck runs and operates normally. Starts and everything. Does that mean it’s not the control module?

How much was the programming at the dealership?

Hey bud I’m having same problem with my truck I’m going to do the same test tomorrow, was wondering if that was the problem to yours or was something else as well thank you

[@srtdetonator5272]

I had mine go bad about 4 years ago. Replaced it with a plug and play from O'reilly auto, worked fine but ever since putting it in, my monitors won't reset. Now 4 years later still no monitors, but I recently started smelling gas while driving. No driving issue yet other than it is cranking longer than normal. Could this be related? Thanks

[@darrellstokley1686]

Because there is a big problem with the dorman fuel pump control module that's why they stop selling them I bought one did the same thing you got to get a AC Delco one and get it program by the dealer unfortunately you won't be able to pass emission test for inspection unless you know someone

He proved pump worked when module was by bypassed, then proved module was getting power. That means the module wasn't routing the power like his jump experiment did because there is something wrong with the module.

it's worth the extra few bucks to buy a module that comes pre-programmed. it's only $50 or so bucks more.

Broke down 5 hours away from home bought a new pre-programmed one truck wouldn't even fire.

Hi Dieseldog, Hoping a response from you. I own a Nissan Qashqai Automatic 2012 Accenta 1.6 and I am based out in UK. I am desperately seeking information as my car is central to my life. After a lot of research I arrived at your video for Fuel pump control module. I have been having sleepless nights as buying a new car is not an alternative for me now. Mechanics couldn’t find the issue even after many fixes. My car has been cutting out on power while driving, that is the car stops totally without any power specially at the traffic signals. It will take a while for the car to turn on and starts to do the same. My gut confidence is .. issue is something with the way fuel is delivered. Mechanic has replaced Crank shaft sensor, replaced spark plugs, replaced Air mass sensor due to P011016 error code and replaced Throttle body. On top of it verified the fuel tank and cleaned the fuel in the tank filter. Nothing helped the car continued to give the issue. After this a Bosch Fuel pump is fitted. It looked very promising without any issue for first 3 weeks and the car cutting out on power specially at traffic signals has returned back and it wont start immediately. It takes a while after many reattempts to start and I get back home. After a lot of research I arrived at your video for Fuel pump control module. What are your thoughts on the issue.I am narrowing down the issue to Engine control module or fuel pump control module. Hoping an answer. Let me know your thoughts please.
