1993 Pontiac Bonneville Repair Question
Pontiac Bonneville Spark Problem
Any applicable mil codes? You should be able to check those codes, yourself. You use a jumper wire at the A & B terminals of the datalink connector. Turn key just till the dash lites come on, no further. The mil on the dash starts flashing, you count the flashes to get the codes, your looking for two digit codes.
When the problem occurs, have a helper crank it while you visuall check for spark at the spark plugs. If you have spark everywhere use a gage and check fuel pressure.
