I am trying to fix my Mother's 1993 Chevy Astro van. The fuel filter, fuel pump, relay, injector, and computer have all been replaced with new parts. The van will run for about 10 seconds when gas is poured in, but cuts right off. Otherwise, it will not turn over or run at all. It does try to turn over. What else could it be? Please help-in desperate need. Thanks so much.

Did you check for any codes? Sounds like the injectors aren't pulsing. Did you do any testing, before you replaced anything?

Did you check for voltage at the injector, with the key turned on? Can you check the injector/s ground circuit with the engine cranking?

With the engine cranking, is there an rpm signal?
