Thanks for the video, I'm getting a P069E & P0231 (Fuel pump relay control circuit low) on my '09 Avalanche. Runs and drives fine, I checked the fuel pump relay control circuit for continuity from the ECU to FSCM, and no issues there. I'm getting 11v on pin 13 of the FSCM connector so obviously, it's not low. But I didn't check the tab on the pin terminal you mention so that's next. Other than that I have no idea what it could be other than the FSCM reporting erroneous errors.

[@SpartanAutoworx]

If I had to roll the dice I would say bad FSCM.

I'm working on a 2018 Chev Equinox with the codes P12A6 and U18A2. When I pull the fuel pump Driver Control Module enables Circuit Performance. The Module wiring clip was full of water. The hot terminal and the ground terminal were in line with each other. the water in the clip made a short from the hot terminal to the Ground terminal, melting the hot terminal. The hot terminal was melted down to the base of the fuel pump driver control module. There is a cover on the body cover that has 2 vents in the cover for air, but there is one vent that is right where the module is located that when you are driving in the rain the front tires are throwing water right back into that vent opening. There was no seal or dielectric grease on any of the terminals. Every terminal in the clip is rusted. The vehicle has 45,000 miles on the vehicle. I contracted GM on the problem and hope they will solve the problem and stop the water from getting into the Module.

[@anatolyice4592]

Can you tell me how to properly stand the green seal-gasket? I have a contact on the " - " (minus) gives an error. Then I disconnect and reconnect the connector, and everything is fine. What could be the problem?

[@arrondentinger2086]

Have you ever seen one of these modules cause drivability issus and set a P0628 fuel pump low voltage code? I've been chasing this issue for days on my daily driver that is now parked. Also, the inside and outside lights flicker while its running. Originally I thought I had a failing alternator so I replaced it. That did not fix my issue. Then I went through and cleaned all of my grounds since I live in the rust belt and the frame is crusty. Still no change... I'm sort of lost at this point and I would be grateful for any helpful suggestions. This is on a 2012 Sierra 2500HD with the 6.0 gas engine.

Have a 2009 silverado 5.3. Truck died suddenly 5 yrs ago. Changed out this module with a plug and play from O'Reillys and the truck fired right up, no problems. Then came state inspection time, for the last 5yrs, I have had no obd monitors working so inspection is a blast. Could this be why they stopped working? This happened right after changing this module.

great video thanks i have 2008 escalade 6.2l i'm working on and customer complaint is sometimes at light engine stalls and dies, but restarts and runs fine for awhile till it does it again. no codes what i found is when it does this, the fuel pressure (mesured from the rail) spikes up to 50-55psi and the needle goes crazy and engines runs bad, bad. do you think this could cause this over pressure condition? thanks

[@jakubvymetalik3321]

When I jump terminals in cross than pump will not prime. but if I test the pump with 12 v power directly the pump works. All pins have a power on socket as per your video. Any ideas?

I tried testing the pump by jumping power and ground directly to the pump terminals, but the car won't crank then. I assume it is an issue with the communications bus?

[@SpartanAutoworx]

Did you put power to the STEPS TO DIAGNOSE: 1. CONNECT PIN1 (BLACK GROUND) TO PIN16 (PINK GROUND) 2. CONNECT PIN32 (RD/WH BATT + ) TO PIN47 (GY FUEL PUMP 12+) THIS WILL POWER THE PUMP TO RUN AND CHECK FOR A FAULTY FUEL PUMP.

[@ricepadi29]

Have a new fuel pump and new fscm I bought from you. Truck died first day out after driving for about 25 miles. Truck will start and die after a few seconds. Pulled the big connector to do power test with test light. Test light come on when I touch the big red and white wire and also comes on when I touch the big black ground next to it. It didn’t do that before installing. I also ran the jumper wires on the plug and can hear fuel pump click but does not start. Any ideas?

Great video i have a 2013 Yukon why don’t i have fuses in my fuel pump slots does the fscm take over them for Power instead because I’m gettin no power at the two fuel pump fuses and my truck no starting

FSCM gives the power for the pump so pump slot will not have fuse.

So when you use jumper wires to test fuel pump do you actually criss cross the wires on the connector? Or jump them straight down on the same side?

Should be cross but dont have the diagram in front of me. You can find it on our website.

Can the bad FSCM work sometimes? I recently had issue with mine, replaced pump and worked for about 2 weeks. Then the truck died on me and had it towed home. Same codes as when pump went out but this time after removing fuse and relay (underhood), disconnecting battery and even unplugging and plugging back in module, it fired right up. Can scan tool tell you if there is an issue even if its running? A few years ago the harness by the front driveshaft had got caught and cut about 3 wires which I repaired (cut and soldered back) and has worked fine. But this last time, I just moved the wire checking if maybe it had come in contact again with the driveshaft but was not the case. I ordered a replacement FSCM and will have it programmed by a local tech this week but I'm concerned that maybe it may not be the FSCM and maybe related to wiring. Any thoughts?
