its behind the panel between the b and c pillar, driver side. and it is very unreliable after all this time. the easiest way to bypass it if it is your problem is to run an earth directly from the fuel pump negative to the chasis.

i have been having huge issues with my fuel system and have put it down to this!!! we have tryed everything else!!!!! so run a spliced earth straight to chasis in the boot somewhere??

is this the metal box thing thats similiar looking to the attessa ecu etc in size?

we are no looking at completely removing the module all to gether. has anyone dont this before? will it be stuck on high voltage all the time once the module is removed?

removed the module and ran a separate power supply to fuel pumps via a direct feed (relay controlled).

yes same...and no ill effects, although it is a race car it also gets road driven a fair bit.

and yes to answer the earlier question - just run it straight to a good earth in the boot somewhere.

could someone draw up a quick wiring diagram showing me how to bi-pass the FPCM?? Please pm it to me! or post up here so others with the same issue can see! cheers!!!!

Bringing this one back from the dead...

My car would run for about 30 seconds - a minute then cut off. I'd let it sit for about 10 minutes then it would fire up and run again for 30 seconds - a minute again. Eventually it just wouldn't start at all. 

Pulled the line off at the fuel filter and cranked the engine and confirmed it wasn't getting any fuel.

Just replaced the pump and the engine still isn't getting any fuel. Would this mod fix that?

Stock ecu, walbro 255, has been running perfect before this.
