Please help! Engine dies when it warms up.
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.
1990 Suburban 2500, 3/4 ton, 5.7L
check pick up coil with a heat gun to see if spark goes out and or heat up ecm to see if ecm is the problem
