Welcome to the forum!
I wouldn't think it's injectors either. I'd think it would at least fire and run really bad if 1 or even 2 injectors were failing.
First things first, do you have an obd2 scanner or monitor? there's a couple parms that are real real useful like the ICP
, along with FICM
logic and FICM
main power. This can help the guys tat are smarter than me (lol) determine whether it's a HPO thing, or a FICM
The HPO stuff is pretty straightforward - depending on the engine build, you've got a handful of parts that are known to leak off pressure enough to stop the motor from running.
Next, can you check your fuel pressure? Unless it's the fuel pump, I don't think that's it, but it's something you'll want to know if you own a 6.0 lol
aaaaaaaand, do you know the build date on your engine? i forget the cuttoff date, but some 04s have the 'early build 6.0', other have the later. makes a bit of difference hunting sensors and HPO leaks and stuff...
next-to-lastly, did you delete the egr
yet? semi-related, is it programmed (tuned) to ignore the egr
function, or is it running stock tuning?
Lastly, does the truck currently not start as it is now (crank-no start)? Also, keep those batteries maintained, a weak set of batteries will kill a FICM
if it's not already started killing it... we can help you figure that our too if need be
