None of these were the problem, when I turn the key to the on position, the fuel pressure gauge climbs upto 2 psi. After the pump cycles the pressure drops to 0. If I prime the system the pressure will climb to 10 psi, then promptly die off as the engine stalls out again. I have changed the pump twice just to find out the problem still exists.

I bought a 1997 Chevy Blazer that was not running. I put a new battery in it and checked for spark. It had spark going to the main wire on the distributor, but the fuel pump was not pumping.

I need to know how to check the fuel pump relay. If it is good, my fuel pump is bad. Can I by-pass the internal gas tank fuel pump and put an external one on. This is for a 2001 chevy blazer.

Already changed the fuel filter.

I have 1991 Chevy S-10 Blazer, 4.3L with about 174,000 miles. It had been starting with no problem then one day when I went to start it, it won't start. Cranks over good, then found out that no fuel was coming up to the throttle body. Thought the fuel filter might be clogged, but nope. I had removed the tank and removed the pump and all. Hooked up the pump with fuel in a bucket to see if it would pump, I might get a drop or 2 or fuel. Now I am being told that either the oil pressure switch or fu
