1996 Chevrolet Van G1500 stalls
(Red Bank, NJ, US)
NJ 1996 Chevrolet Van G1500 143k stalls while driving. Chevrolet van stalls frequently, but not reproducible consistently. Have had fuel pump replaced twice before, when checked OK, also wiring connections OK, replaced gas filter, new battery, new computer (reprogrammed following replacement)and mass air flow sensor.
Typical occurrence is seems to stall when starting to re-accelerate after coasting. When car stalls can shift to neutral and re-start immediately. Often stalls 2-3 times again but then will begin running. Doesn't seem to stall when accelerating.
Possibilities in mind so far (1) faulty intermittent alternator (2) faulty electronic ignition module (3) carbon build-up. Any shoot-downs of these or thoughts about anything else?
