1989 Chevrolet Pickup K2500 5.7L Charging
Posted to GM Electrical on 11/7/2000

Computer shows no codes; stays in open loop mode doesn't change to closed mode. When I plug in connector that advances time with timing light it advances up to 30 degrees then retires to 30 degrees below top dead center.
