This is a pain in the ***!! It says its something to do with the fuel supply ECM????

Anyone had any problems with this code before?? I can't delete it with HPTs and I don't want to take my truck into the dealership with the mods I have on coz it will void warranty, so would rather fix it somewhere else...


any ideas?!?

 

i have seen that code too, did research on it, didnt come up with anything.
it prevented the truck from starting, a simple clear dtc and it worked, it never came back.

 

nice ill give it a shot...cheers

 

any update on what this code does?? i have an 07 throwing this code and as much as i can clear it...it keeps on coming back..

 

do u ever get hesitation at WOT when the code is on?? One thing I found out was my fuel pump was shot.. the only way i've heard to get rid of it is to take it to the dealership where they'll reflash the "processor" for the fuel. not too sure what it is, i sold my gmc before i did anything about it

 

yep sure does, clear it and its fine....buuuuuuttttttt it keeps on coming back

 

I'm sure it has something to do with the fuel pump...if its still under warranty take it to the dealership..... mine started happening when I installed my cam and my injectors were maxxing out.. ever since then, it was constant..

 

Yeah this code is thrown by the fuel pump module, not the pcm.

 

There we go, thats the "processer" i was talking about! I need to read more books lol

 

Good info guys...I learned yet another tid-bit today that i am sure will come in handy in the future
