1992 Chevrolet Astro Repair Question
Chevrolet Astro Engine Problem
Have you checked to make sure the pump is producing pressure that is within the manufacturer's specs? To me it sounds like you have what we call a lazy pump. It doesn't produce enough pressure to start but will keep the engine running once started.
