Asked by Nov 25, 2011 at 06:53 PM about the 1990 Chevrolet Suburban V2500 4WD

Question type: Maintenance & Repair

I have replaced the ignition control module, distributor cap, rotor, ignition coil, spark plugs and wires, fuel filter, fuel regulator, new battery and altenator. Ugh! Once the engine is nice and warm the engine quits. I am frustrated.
