Ok guys i have about had it with this thing.I have 2005 excursion with a 6.0 it isn't firing on the right bank.FICM tests good,Good ICP,I have confirmed fuel to that side of the motor.I checked the FICM wiring and all was good with that side.I changed oil and all the fuel filters.It just died one day going down the road.Prior to that it was rough to start like it had a couple bad injectors.I have since replaced injectors on that side.I have cranked this thing long enuf to get air out of the system.Any ideas?? The only thing i hate more then this truck is the Duramax i own.Please help before i resort to TNT!!!!

 

Is the truck stock? does hit have any programmer on it? if it is only the one bank not firing it is going to be the FICM, they can test good for voltage but they can still be bad, that test only does the power side, not the actuall brains of the FICm.

 

Sounds like a new ficm and maybe a harness is in order
