Yep,that sounds like the fuel pump is getting hung up on the bearings.don't forget to put a new fuel filter on too!
you'll see the blackness of the fuel that got stuck in the filter.

Not sure what to do but the 2000 chevy silverado 1500 Z71 V8 truck that i have wont take in gas. we thought that it was the fuel pump so we replaced that and the fuel filter but the truck still wont start....

Did you check the voltage to the pump to insure it was getting full power? Check the fuel pressure regulator? Also take a manual fuel pressure reading. A faulty crank sensor will also cause a no start condition.

You should not see any voltage after the 2-second prime until you actually start cranking the engine. If you don't see power on the grey wire when cranking, try jumpering across the fuel pump relay terminals

2000 Blazer Cranks, Won't Start

First of all, a diagnostic wont tell them that there is arcing involved. I am thinking it is your crank sensor. It expands and retracts in different weather situations.It should make contact in all weather situations.
