Engine turns on and shuts off? PCM issue?
Hi all,
I am having another issue with the Aspen. The truck starts and turns off right away. I’m getting a “no bus” message in the display. I am wondering if the PCM is wet or has a loose connection and would like to check the 4 plugs.
Can someone advise or provide a picture of its location? 5.7L.
If I unplug it and plug it back in, will it need to be reprogrammed? I do not want to go to the dealer and get a new PCM if there is simply some corrosion or a loose connection.
Need this truck running ASAP as it is my only transportation, any suggestions or comments are appreciated.
Thanks,
