FINALLY found the right video about this issue! Live in upstate ny (30 minutes south of Canada), lake effect snow capital, and have issues with wiring harnesses. My problem has been intermittent, and just so happens my spare is off too, so I’m doing this same procedure in a few minutes. Hope it’s the problem as my pressure is low on my pump randomly . Thank you !
What a good video, thank you. I was interested to see you can jump across the module to prove the module is bad. It made me wonder if one might be able to avoid a tow by temporarily jumping across the module to get the vehicle home. On the other hand, that might cause a problem by forcing a continuous run from the pump. Is there a waste fuel line going back into the tank for excessive fuel, like old style pressure regulators? I wouldn't want to run the pump to excessive high pressure and blow the pump while trying to get the vehicle home.... Presumably the module takes pressure feedback from the line and adjusts a PWM performance cycle from the pump. What do you think?
This system is a returnless system that uses PWM power supply to regulate the fuel pressure/volume. You probably could jump it to force it to run but it may damage the pump. I’m not totally sure. Thanks for the feedback though! Appreciate it!
Excellent video. I have a 2010 suburban with the 5.3 vortec and same symptoms. I've checked and changed fuses 4, 5, 12, 21, and 56. I also installed new fuel pump and Fuel sending module. I jumped the harness and fuel pump came on strong. I purchased the preprogrammed module from O'Reilly and still nothing. I'm guessing I'll need a mechanic/dealership to program the module next.
@@jamesedwards794 Not immediately, the last thing I did was check all the grounds and the positive cable with the 175 amp fuse. I changed the negative cable and sanded down the grounds and crunk right up and has been running ever since.
I had the same issue, replaced fuel pump truck would run, then it would show u0109 replaced module still shows u0109 but runs as should I think, weird and annoying issue. Went to junkyard got a fuse box that didn’t take care of it either
Thank you Tom great video i'm gonna replace mine and see if this helps,so far my 98 chevy Silverado has shut down twice while Idling coming home from work about a month apart.
I got my fuel pump control module replaced and reprogrammed, and my check engine light is still on for the control module. Would it be a wiring issue?? My code that pops up is P069E
I think that's what my truck needs. Fuel pump replaced but didn't fix issue. does the doorman one come pre-programmed with and for electric brakes? Great video btw 👌
My fuel pump turn on manually but not automatically the truck turns on and idles rough for about 20 seconds before turning off any idea on what it could be??
so i had just replaced my module about a week ago. my truck started, but kind of chugged. after a minute, she ran good and i was able to drive it home. about 2 days ago, i started her up, and she wouldn’t stay running. does the module need to be relearned or do i have a bad module?
My truck started shutting off and dash gauges started going crazy. I took the fuel pump control module fuse out everything went back to normal but it wouldn’t crank. I’m thinking there’s a shortage in it somewhere
Hey i got an issue, my 2003 gmc yukon keeps having issues every time i drive it, my truck messes up and shows on the dash reduced engine power and stability control system. Any idea on what it could be? My mechanic couldnt figure it out and ive seen your older video about the reduced engine power but since both of these lights come on i dont know if it is something different.Im just not sure on what i could do to fix it myself since my mechanic couldnt figure it out. If anyone has any ideas on what it could be id highly and greatly appreciate it, thank you.
@@nmaauga check the fuse for the control module and replace the control module , mine started shorting things out in my dash to the point to where it wouldn’t start , that module may have a shortage in it.

Thanks for showing the wire jumping and twist and pull tip is nice! Thank you

Did it work after the program ?
did you figure it out ? same issue here

@@crod1449 Yes, I ended up changing the negative cable along with sanded down the ground points and it crunk right up. No issues and still running.

Does the key need to be in the on position when jumping the those wires to see if the pump comes on?

Is the location of the module a possible cause of failure?
I think that's what my truck needs. Fuel pump replaced but didn't fix issue. does the doorman one come pre-programmed with and for electric brakes? Great video btw 👌
Yes as he said in the video, the dorman fuel pump control modul is pre-programed and ready to go
What if I hear the fuel pump kick on but no pressure at the fuel rail? Could the pump still be faulty or could it be with the module? Thanks
Fuel pump kicks on manually jumping it fuses are good and a new fuel, pressure module and it still does it. What could it be?
You could have a broken wire between the ECM and the fuel pump control module. Sounds like it’s not getting the signal to turn on.
@@Tomsfoolery. thanks for the help fuel pump was only pumping 10 psi with key on changed fuel pump and good
Where can I get the jumper wire?
will that fit on a 2013 silverado 1500?
Wow! Good job, good job 👍

It needs to be reprogrammed
Also reset alcohol level with scanner

Mine is doing that too
@@MikeSmith-nu9wt it was the control module itself. Had to order one and get it programmed
Great video

Have you had the vehicle scanned? If so, what codes are active when the issue presents itself?
Hey my truck is doing the same thing did find out what was the problem
@@nmaauga check the fuse for the control module and replace the control module , mine started shorting things out in my dash to the point to where it wouldn’t start , that module may have a shortage in it.
Could be a bad plug or coil , that is what my problem was.
It's your accelerator position sensor my 08 Silverado 5.3 1500 Lt had that issue good luck
Great video buddy!
Thank you!!!
I put in a new fuel pump later on I got a code p069E and on the fpcm I have p2635
Yup...let's put 50,000 modules in every modern vehicle so that they can be constantly sitting on the side of the road.
