My truck is stalling out at random times without any rhyme or reason. Fuel pump has been replaced and some wiring under the battery plate fixed from being frayed. When stalling I have measured a consistent 58 psi so I do not believe it is with the fuel system unless it is after the fact at the injectors. One thing I do notice is the check engine light does not come on when I cycle the key to the position just before starting. I believe that is telling me the PCM is not going through its initial startup sequence.
I have also had a couple problems where I cannot shift the car from park and that usually fixes itself quickly by cycling the key on and off.
Is it possible the ignition switch is causing communication issues with the PCM circuit? If not any other ideas?
I do not have any active or pending check engine codes.
appreciate any help. Thanks!
have the same problem?
