1990 Chevrolet G Series Van (G20) Q&A
1990 Chevrolet G Series Van (G20) Question: No spark from the distributor cap?
Check the ignition pick up AC Delco part # 10496783 about $28 at your local parts store, But have them double check that number - Valleyautotech
sounds like you need that small wireing harness autozone has them - Visitor
Replaced coil and had module tested, both are good, still no spark, no sign of distributor cap problems?
