New Fuel Pump For Me

New Fuel Pump For Me Well, looks like its the fuel pump. I swapped relays with my AC unit (they were the same numbering ect.) and it still cuts out on me. Going up hills and on right-hand turns most of the time. Anyways, it died on me near the house so I got out and turned the key to "run" and pushed in on the schrader valve on the fuel rail. Nothing. After 10 minutes it cranked (banging on the tank ect. was no help, it cranked when my dad started to push it and I tried once more). I drove to the house, shut it down, removed the cam, pushed in the schrader valve, and it pissed all over the place. Definitely a fuel-issue that killed it back there. Fuel filter is either clogged or its not. I belive the fuel pump is bad. Any observations/help/ect? (oh, if it matters it has better than a half tank of gass and had 4/5 tank when this started).

When it's hard to start, can you hear the fuel pump priming at all?

If not the filter, then it's probably either the pump that's bad, OR, you have an electrical power/ground interrupt issue to the pump. I know you tested the relay, but it could also be a wiring issue. Checking wiring is a pain in the *** though.....

That just happened to my mom's car. Ran a Tech 2 scan on it and it was adding a lot of fuel so I figured it was the pump. Replaced the pump and all is well. If I were you, I would check the wiring going to the sending unit. My old LT1 Formula had a bad connection there and would shut my car off randomly. Nothing was wrong with the pump.

Where/what/how? I have already swapped the relay.

*done. It was in place, tight, and in good shape.
