Have Ford Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner till early morning.
Any codes stored?
Does it run with a bad misfire?
Any exhaust smoke concerns?
Does it idle fine?
Are you saying the PCM shows no codes or the scan tool will not link up?
After 30 seconds does it act like there is a misfire?
At the data link connector is the light green/red wire powered?
Are the black/light blue and black/white wires ground?
Thanks, ***** ***** on those DLC tests I outlined?
Have you verified your scan tool will work on another vehicle?
We must get a diagnostic tool to connect to figure this out since we know the passenger head injectors are dropping out and you have addressed the wiring and IDM. So we need more help from the scan tool to see why to avoid checking all of those wires for issues unless you prefer to do that from a wire diagram I can send?
Can you do these steps to diagnose the scan tool communication concerns. https://dl.dropboxusercontent.com/u/90220402/PCMcomm.pdf
Thanks for using Just Answer, and rating me so I am compensated, Chris
