1993 Pontiac Sunbird Repair Question
1993 Pontiac Sunbird firing order
1993 Pontiac Sunbird 6 cyl Two Wheel Drive Automatic 130000 miles
I Want to check that the spark plug wires are on the right spark plugs, and how to test the coil packs?
My info showed this firing order for the 3.1, did you visually check for spark at the plugs? You can pull a spark plug wire, use known good plug or spark tester in the boot, ground metal part of plug/tester to metal part of engine. engine cranking, watch for spark. I wouldn't think all your coils would fail at the same time? Any applicable codes?
I got two or three databases I use, they all have mistakes. Maybe this is better.
