Spare FPCM (Fuel Pump Control Module) WISE IDEA!!!!

[KMeloney]

Just got mine in the mail today. Thanks for this thread!

Glad you guys are getting spares in. Kind of like when you buy a new snow shovel or snow blower, you really expect or want to use it, then it does not snow for 5-7 years!

Just did a test of my new module. (I didn't disconnect the battery.) It started and ran fine! Swapped back the original module and I too have the CEL on. I guess I have to do the drive and shut down then restart to clear it.

UPDATE - CEL is off.

On a side note, the little red secure tab/pin that is removed from the connector to disconnect the module, cracked. Can these little red pieces be replaced and if so where can they be obtained?

Thanks!!!

More likely, you'll have to source the entire connector with that red tab.

ETA: I think this is it - Part # 13574909

Thank you for the response. I suspect that you are correct. Possibly there is another connector with the exact red tab that GM uses on a less expensive connector? I guess knowing that is nearly impossible, unless you worked at a GM parts warehouse and could casually compare connectors?

For now, its secure with a broken tab holding it. I may try a plastic zip tie through the hole and see if that works.

Thanks again!

DocDoug, you might be able to find a red locking tab on a connector under the hood that would be less prone to needing the red locking tab, even something you would maybe need to remove when changing the air filter? Then you could figure out if there is a 2-4 pin connector or that you could get from a scrap yard or on ebay just for the locking tab.

Good luck and let us know what you find.

Just got my second one from Summit Racing. Can confirm that 13554821 is still the latest iteration. Also, Summit raised the price on these from $35.99 to $44.99 a few weeks after I ordered mine.

Being prepared, priceless.

Next is the transmission park override cable like I put on my truck.

Ordered my spare module today after a buddy's wife got stranded in her 2021 Yukon. Cost $52.18 shipped from GMPartsDirect.com

Just finding this thread.. I am pretty confident my FSCM is bad though I am struggling to even FIND the dang thing to test it. I have an 08 Yukon XL 2500. I have checked behind/above the spare tire.. only a 2nd fuel tank, no control module. I checked under the driver seat along the frame rail.. don't see it. I checked in the fuse box and I do have fuses for Fuel pump and FSCM locations with nothing for relays which leads me to believe I SHOULD have the FSCM.

Symptoms according to google of a failing FSCM are:
Poor fuel economy (I have been getting 9-10mpg with the 6.0 no towing and mixed town/highway)
Possible engine surge (at stop lights rpm would flutter 1-200 rpm)
excessive engine heat (again at stop lights or extended idle with 100% brand new cooling system engine temps creep above 210)

I was at 1/4 tank of fuel and other than the above symptoms everything was starting normal and otherwise driving fine. Went and put a full tank of fuel in (of course it happens when full) and now I have a full blown crank/no start situation.

Where would I find this control module?

I have never looked at 2008 for the FPCM, however, based on the YouTube link below, it appears that is below the drivers side passenger door on the inner frame rail in front of the ABS controller. Seems somewhat hidden or tucked up above a cross member?

Also note if the module has the small double sided arrow with a wrench iton the right upper corner of the label it will need to be programmed unlike the newer models. See the below YouTube link around 22 seconds.

It may be possible if you purchase a used module, it may not need programming, not sure about this. Unclear what the programming for this module does. If it need to be VIN matched, then it will need to be programmed to the vehicle.

It might be that the same module fits different models and it is just model programming, but if this is the case you will need a module from the like model.
