Truck runs for about 1 minute on a cold start. Then it seems to starve. I replaced both fuel pumps, fuel filter and fuel pump relay. I’m not sure where to go next. I’m not much of an auto mechanic, but I do make a living fixing machines and am familiar with automation. (I’m good with voltage and signal voltage.) so I would appreciate any help to point me in the right direction.
The next time the engine stalls, check for spark.
If there’s no spark, the problem might be with the Thick Film Ignition Module.
This module can be mounted on the distributor, or on the radiator core support under a rubber cover.
