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.

No I havent checked the pressure to see what it is. The pump is fairly new within the last 6 months I did the replacements. What should I get for a reading autozone said the pump is the hi pressure one for the vortec about 90 psi is what I was told
