ok, some might remember that i got rearended a month ago. well... the car is almost done, they just have one last problem that they can not figure out, so they asked me.... but i wanted to see what you guys thought because i know that some of you have more knowledge then i do.
ok.. the issue is on cold starts... when you try and turn the car over it takes 4-5 seconds to start up (it was almost instant before the wreck). when the car finally does start it bucks, idles really rough and tries to stall... when the car warms up it runs flawlessly.
the guys hooked up a few sensors to the fuel line to see what is going on... the FMU registers one number, but the actual numbers comming through are a bit lower... take off the hose going to the FMU and the actual numbers rise to be what the FMU was showing it to be... FMU connected or disconnected it does the same thing. they said it runs really rich till it warms up, then finally leans out to 14.7:1.....
the fuel lines are all fine, no bends or crimps in the line, fuel rail is fine, checked the plugs and most were fouled because of the mass of fuel comming in, they cleaned them off but still no change.
they are going to replace the fuel sensor since it is registering higher then actual output. I also suggested to get rid of the pump and try a 03 cobra pump and see if the new pump can take care of the issue.... also, could it be the computer? something just off on the readings that now just needs a reflash?
anything you can offer would be helpful.
