Fuel pump?

I have a 1997 chevy astro awd with 146k, when cold starts right up, after run for an extended period, 1 hour or more becomes hard to start. Cranks for up to 15 seconds then starts, I noticed oil pressure gauge is at zero while cranking then shoots up to 60 lbs. And starts right up. Fuel pump and filter was replaced [non oem] about a year ago. Thanks joe mac.

The fuel punp circuit goes through the oil pressure SW. Replace it and I think you problems will be over. It is located on the top rear back of the engine. Good luck

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
