I am a little puzzled as to what the real issue is with my 04 Ex and would like some thoughts. Since it is the weekend I have no access to a scanner but will do so on Tuesday. I have done lots of looking as to signs of a failed FICM
but none seem to like what I have I believe.
Within the last three weeks I had studs put in, Airdog 2, bullet proof external oil cooler and filter, powermax, GoGo stage 1 intake, new 155 injectors, NADP tranny, HPOP
, coolant filter, alternator, coolant pump, and 7 gauges.
Got the truck back from all the work done and was running good no issues. I get a custom tune loaded up and everything is all good then I go to start it up in the morning the other day and nothing just cranks over. I read the codes from the SCT and it was P0603
and U0105 I clear them and then it starts. It runs good for a few more days then go to fire it up in the AM and nothing I get the U0105 code again and the low voltage code as well. I rip all my intake piping apart and unplug the harness from at the FCIM and follow all the wiring back to the PCIM a little wear noted but not through the outer core of the harness. Uplug and blow all the dust from the PCIM and go to start nothing. Check codes same one U0105 cycle my key 5 times or so wiggle the connector at the FCIM and then it fires up.
The truck does not run rough at all.
After looking at the wiring harness I can rule out a broke wire I think. Not a fuse as it would not start at all right? I can only think that it would be a FCIM or a PCIM. Batteries are new within the year
Before I took my intake piping apart from the mechanics shop to look at the harness I would make about 30lbs of boost at WOT
on a performance tune. When I was at WOT
it would sputter and drop down to 24lbs all intake piping is secure as I thought that I blew a rubber off the intercooler. After taking my intake piping apart I can not get anymore boost than 20lbs of and she smokes bad at WOT
. My turbo is making more noise in the cab and kind of freaked me out. Now I am thinking that the mechanic did not have all the intake piping secure and I was able to make more boost because a hose clamp was not secure and she was sucking more air in.
I have a FCIM from innovative on its way
Thanks for any thoughts
