Thank you 😊 dude it was the green seal ....u made my day brother ...
I just bought a FSCM hopefully everything goes back to normal when I get it and install it!
Pro trick : you can watch series at flixzone. Been using them for watching a lot of movies during the lockdown.
@Braydon Rex Yup, have been watching on flixzone} for since november myself :D
Did everything go back to normal?
Yeah dude everything go back to normal ?
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.
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.
Добрый день! Можно ли увидеть фото платы блока fscm chevrolet express ? От попадания влаги, отвалились некоторые детали.
I have a 2009 gmc acadia the engine will run and stop quickly check for signal for fuel pump found pump comes on but signal stops quickly does the fuel pump have constant power with key on
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?
I got a P129F on my 2019 silverado, its been at the dealer for a week under warranty but im getting impatient. its backordered, kinda wanna get a used 1 from a salvaged one.
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.
If I had to roll the dice I would say bad FSCM.
Did you replace the module? Same issue here, code for poor pump performance but truck runs perfectly. 09 Sierra 1500
@@joshrayco9535 Yup it was a faulty FSCM
@@SpartanAutoworx Question i’m getting code u0109 and the car won’t start i checked the fuse and keeps blowing every time i replace it any ideas
Will that particular module part number work for my 2010 Escalade esv?
2010 Silverado, engine cut out several times while driving and wouldn't restart for about 10 minutes. Throwing codes p069e, p0231, and p0449. Fuel pump recently replaced. Would this be the control module ?
I know this is has been uploaded for 10 months now, but this has been super helpful! My 2008 Suburban has a U0109 code right now, but runs and starts perfectly. Have you ever heard of that happening? I keep getting U0109 and P069E after I drive for more than 30 minutes, but it doesn't shut down or studder or anything. It still runs perfectly even now. Seems like a short of some kind, but wasn't sure if you had ever seen that before.
If its not a break at the connector wiring its a bad module. Yes I have seen it just not common.
Check pins make sure no corrosion.
@@SpartanAutoworx Thanks for the tips!! Can you detail where that other connector is that you mentioned at 3:18? It confused me a bit and I want to make sure I look in the right spot for it. Thank you so much!
happened to me ten mins after i pressure washed power steering pump. ( i had a leak)
Thanks for the vid very helpfull and i need to order one u said they are programmed
Depends on the year you need but yes plug n play
This helped me out..thank you
Glad it helped
@@SpartanAutoworx I have an 08 gmc sierra that just stopped starting. It will crank but not start. I just put a fuel pump in it 5 months ago due to pump being completely rusted out. Northern Illinois is pretty ❄.... I may need to buy one
My 2009 Silverado has code P069E request Mil iluminate, the trucks runs perfect at idle or at speed and acceleration. I clear the code but it returns.
Fuel pressure is 50 to 55 lbs. Do I need a new module?
Prob bad module
I have a 08 Silverado truck was dead changed module truck ran fuel pump module and frp sensor is new still got a p0191 didn’t have this issue until replacing the FSMC any idea?
So I have a p069e I replaced the module truck wouldn't start so I put the old one back on and it fired up... any suggestions on could be the problem?
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
I am not getting power to pin 15 pink wire, any advice on where to look for the fix, thanks!
What kinda socket do I need to remove the fuel pump control module on 09 Tahoe.
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.
Dorman module….. This is common issue from that brand. Need to replace with a real module to fix it correctly. Contact us if you want a replacement.
@@SpartanAutoworx thanks! I already purchased a new GM one. Can I send it to you to program?
Ay bro problem I have is locating the FPM ON MY 2012 Chevy 6.0 rwd....
The one I see look like brake trailer module....
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?
So if you put power to the pump does it put pressure at the rail? If not bad pump bleeding into the tank.
@@SpartanAutoworx it was bad modul indeed . still buffled why I was unable to test pump from socket.
Great video. You explain it well. My question is I’m getting a PO69E and PO59F code,( grill air shutter,) are the two related?
2013 Malibu. The car runs fine.
Would not be related.
You have a P069E code, not a PO69E. Will be related
Will that be the reason my pump does work?
I put 2 new pumps the first one did work but not long only l I ke day in half I cam back to crank truck only turns over no fuel pump buzzing or pressure at fuel rail
If equipped yes that would be the issue
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?
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.
U described good put visually showing it u need to work on.
Long shot here. Got an 08 escalade. Starts up fine runs alright. When the converter locks up and I accelerate fuel pressure drops to low 30s causing hesitation like a misfire. Brand new fuel pump didn’t fix it any ideas?
I would guess FSCM but not sure why only at lockup
What is the part number for the connector or how can i purchase one??
We sell them. Email us at spartanautoworx@gmail.com or call 636-795-6960 on Monday. Just need to know if you have a Lh or RH connector. Look for the R or L stamped into the back of the connector.
Hey buddy thanks for you good info .
I have an 08 Denali. Everything works fine! It snowed really bad for a few days and then my fuel gauge stopped working. My check engine light has been on for a few months. I ran a hot wire from my fuel pump to my fuse box. What could be the reason my gas gaug is not working and check engine light is still on?
Following this question…
Awesome video thanks alot
I got the code p025a fuel pump module on my 2008 silverado 4.8 the truck turns on but in when I’m the road and I hit the gas it wanna turn off and when u park and turn it off and back in it don’t wanna turn on it just sounds like it wanna turn on but it does after couple minutes of been turn off you know what could that be
Sounds like bad FSCM
Awesome videos! Really appreciate the diag info. 09 Sierra 1500 runs mint but code for poor pump performance is setting mil. New no name pump a year ago Will test actual pressure at rail but is there a pressure sensor that reads rail pressure? There isn’t one on rail or under hood anywhere… helping a friend with this so any tips are definitely appreciated!
It does have a sensor near rear of truck
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.
What happens when you jump them straight down on same side?
I need one what’s the price?? 08 Yukon xl!! I drove through some water That was deep enough to go past the runningboards a couple days after that the truck started stalling out and getting weird codes and just last night it’s daughter on for about a half hour the message center in the dashboard Showed hood open So I got out and checked and hood it was still locked and while all this was going on the alarm would not arm
On a 2012 GMC Acadia does the FPCM comes pre programmed
No it does not
09 gmc sierra fuel pump runs all the time with key off and will kill the battery but otherwise runs great. Po232 code shows. Bad fscm?
Yes bad fscm
Thank you
You're welcome
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?
So if you bypass power the fuel pump does not stay on?
No the fuel pump just makes a single click then nothing.
I have 07 silverado and no power any where to fscm but truck will crank and run for 5 minutes or so then go dead with no fuel pressure . already installed new fuel pump would fscm b bad in this case
UMMM so no power to the red and white wire? Truck would not run if thats the case.
How do you order one of those do your website
I'm getting replaced at the dealer.
Told me had programs to truck.
True or could i bought one preprogrammed and install myself?
Depends on year
Question i’m getting code u0109 and the car won’t start i checked the fuse and keeps blowing every time i replace it any ideas
Module is shorted either water inside the module corrosion or something shorting the actual connector pins.
Hello, I am currently getting a code (P069E-00 Fuel Pump Control Module requested MIL Illumination)- Cadillac ATS 2014 3.6L
not sure what really needs to be replaced. But its a little strange every time I head to the gas pump and fuel up the car., it starts to loss power and turn off. I would need to start the car a few times and also apply the throttle to get it up and running again. That only happens when every time I head to the fuel station. Can i be the fuel pressure sensor? would appreciate the help.
Could be purge valve not opening to vent the vapor
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.
Spartan Autoworx thanks for responding so does the fuel pump on these trucks make any noise when they cut on ?
Spartan Autoworx what’s the website to purchase the fscm
@@regalgsdet let me know if they answer
jordan colwell they didn’t answer but honestly i just went to AutoZone they sold one that didn’t need to be programmed luckily
Will this always show a check engine light? 2015 Silverado died twice warming up, then once going down the road.
Not always
Should the module make a humming sound or is it just silent always.
Module makes no noise
Great video .. thank you
My 2008 gmc is only getting power to the red and white wire on the connector for the fscm and the fuse isn’t blown, why is that?
Nothing on the pink or the green and white?
@spartan autoworx I don't have power to pink and green white, but crossing the 2 big wires to test the pump I hear it come on.. I check with power probe at pin ,51 at ecm it'll have power at key on.
I had to replace the FSCM from auto zone and not the dealer. Check engine light comes on but when I scan for engine codes there is no codes present but check engine light is illuminated. I cleared it and comes back on the next time I start vehicle. Any ideas?
Dorman unit?
@@SpartanAutoworx yes
chewy crunch what’s the codes
I have a 2017 Camaro ss, my fpcm is bad, but I can’t find it’s location on the car. Do you know where it is ?
Should be in the trunk
@@SpartanAutoworx you serious?? like underneath the carpet?? i was told under the driver side wheel well like 3 feet back.
even a dealership didnt know what i was talking about..
currently replaced my fuel pump because i was loosing fuel pressure, my 2013 tahoe still has a hard time starting when cold, idles rough, revs weird in reverse, and when start to drive from a stop it seems like it wants to die then runs right. could this be the module? i have a few lean codes and a fuel pump control module code
Sounds like bad FSCM
@@SpartanAutoworx okay thank you
Would this process be the same for an 08 Yukon Denali XL
yes
Could a faulty control module give low voltage to fuel pump..pump is brand new and when starting the vehicle it hits 60psi for about 10 seconds then falls to 44psi steady..any info would be appreciated
As no codes but runs ral sluggish most of the time..if u stand on it..at about 5000rmps it jumps to 60psi then falls back to 44psi when shifts
I have low voltage right now and rough idle. Trying to figure out if it’s the fuel control module as well
That's exactly what My 2009 Yukon does. 44psi causes rough running, lean misfires and hard starts. Is the FSCM the cause ? I replaced the pump already, and that did not fix the 42PSI condition.
@Carl Zimmerman after a lot of looking..I found out that it supposed to run like 44ish give or take and the fuel pump control module give more fuel pressure as needed..
@@jasonjager1443 mine immediately misfires as soon as pressure drops from 55psi to > 44psi. and if trying to crank/start with 44, it wont start. When pressure returns to 55+, it fires right up. I just replaced fuelpump assy, and it didnt fix the variable fuel pressure problem.
Where is it located on the 08 Tahoe? It isn't above the spare tire. Any ideas?
underneath drivers side door with a rubber water deflector covering it up.
Is there a part number for connector green seal?🤔
Have to buy entire connector
Do you know where Fpcm is located on 07 Tahoe ls
Does not have one
Do you sell the replacement connector for air ride suspension module. For 2009 escalade.
Yes I do. I just need to know if it’s stamped with R or L
@@SpartanAutoworx Ok, will check that out.
Is the pin out different from the 2012 GMC Sierra
No
Ok thanks.
What does it mean if all the wires are good but no power from fscm to pump
Have to also check for power on the green and white wire. If thats not working pump wont kick.
@@SpartanAutoworx yes have power at green wire as well rn Having to run power to grey wire for truck to run and drive cause I have no choice
@@SpartanAutoworx wish there was a way to get ahold of you a little easier lol
Does the module need to get programmed after replacing ? 09 Sierra
If you buy a new one from the dealer or parts store Yes it does
@@SpartanAutoworx 2012 gm c Acadia can you buy one pre programmed
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?
Any codes? Did you check wiring at the connector?
@@SpartanAutoworx the codes I got the both times it died on me were: P025A, P0230, P069E
The first time I replaced the fuel pump and it fired up and ran for 2 weeks and died again last week.
Did u find out what it was? I’m currently in same situation
@@jordanbutt992 It was wiring to the fuel pump control module. Even with the new module, I had it happen again. My mechanic made his own relay and never had an issue with it after 1 year.
What if you don't have power on the pink wire?
Then you have lost ign voltage to that wire from the source.
I have a 2008 Chevrolet Silverado with fuel pump problems. My truck died on me last week and thought it was a bad pump because I got codes PO230 (Fuel Pump Primary Circuit), U0109 (Lost Communication w/ Fuel Pump) so I replaced it. I finished installing it, turn the key over and hear the priming of the pump and started right up. 3 days later, driving and it dies on me and gives me the same codes. I suspect bad FSCM, but not positive. I check what I have learned from this video soon, but now when I turn my key on, I no longer hear the priming of the pump that you typically hear for about 3 seconds when you first turn your key over. I just hear a clicking on and off. Any ideas?
Bad FSCM
@@SpartanAutoworx okay great. I will put in an order. What is the lead time on them typically?
Usually ship same day you order
@@SpartanAutoworx I got my hands on a test light and tested these pins and this is what I found.
Green/white wire: power when cranking
Pink wire: got power
Red/white: got power
Ground: no power with test light
Bad FSCM or bad ground?
I notice in one of your videos with your test light, you didn’t get your test light to light up on the ground either.
What size was the bit needed to loosen the module?
What's your website I need a connector adapter in a FSCM
gmflash.com/replacement-connectors
I can't get them screws out for nothing what type of tools did you use to get the them out
How would u know in the first place if this is broken?
Does the truck run? Codes?
@@SpartanAutoworx no sir
Change the fscm crank no start
Still no start crank yes power and ground
Pull the green seal from connector and hook it without seal
I replaced mine on buick enclave. Won't start now.
Did you program?
@@SpartanAutoworx no
@@SpartanAutoworx I tried the ten second thing, but I think I'm missing something here right? Lol!
Does it need to be programmed??
Yes
