1999 GMC Savana Repair Question
What else should I check?
Asked by heathwilliamsAnswer
good spark where?? did you check it at the plugs??
Roy
yes new rotor cap and plugs also installed has error code p0300
how did it run prior to failing??
Roy
It ran rough at idle like it was missing and when driving at freeway speeds it would surge also rechecked error code and it gave code p1351 no other codes does this mean the ignition control module went bad. Got it to kind of start yesterday at an extreemly low idle then it would die.It basicly acts like it is flooding now and this is obvious when sprayed with starting fluid. Have raw fuel smell at exhaust. The spark as it comes off the coil wire is blue white but then changes to a yellow orange so spark might not be good after all. I have one buddy saying change fuel regulator and another saying change ICM so I'm not sure what to do.
Just checked spark on spark plug and the spark is blue white.
Also the plug is black they were just changed 2 months ago.
found the problem the gears on the distibutor wear missing teeth
