- – Verified concern, found vehicle to start, but have difficulties starting. upon startup found large amounts of smoke to have come out of the tailpipe with engine misfiring. inspected spark plugs and found 2 of them to be fouled and a third to be wet with fuel, cranked engine without spark plugs installed and found gasoline to be spitting out of cylinder 3 indicating fuel injector is stuck open, recommend replacing fuel injector in cylinder 3 and 4 spark plugs to address plug fouling and startup issue engine is having.
- Removed and installed injector in cylinder 3, and tested, after testing, found problem was still present, fuel injectors 3 and 4 would stick open with ignition on, inspected old injector and found open 0 resistance on both pins.. tested connectors to injectors and found power and ground were present with ignition on, traced wiring all the way back to PCM and founf PCM to have stuck signal ground on for injectors 3 and 4, it is likely failed injector 3 has caused injector drivers to fail on PCM, recommend replacement of PCM to restore drivability.
