Engine Performance problem
1989 Chevy S-10 6 cyl Four Wheel Drive Manual Unk miles
The motor started and ran great towards the completion of this restoration project. The motor was not started again for a couple of months while other work was being done. When attempted, it would start and then die after 4-5 seconds as if you turned the key off. Upon closer inspection, both injectors quit spraying fuel even though there is sufficient fuel pressure. Now it tries to start but it backfires and carries on before dying altogether. Does not throw any codes. I'm stumped. Again, it was running GREAT before, nothing was done to the motor between then and now. Everything is new or reman'd including the fuel pump and filter. 12.8v at the battery. Initial timing is correct. Fuel pump runs for a few seconds when key is first turned on. In other words, everything checks out fine, but the injectors lose power and I can't figure out why!
Would falty distributor components cause the PCM to cut power to the injectors?
