Have you changed your fuel filter first? When I replaced my pump, I ended up getting one from Morad Parts...far cheaper than buying a new one, and they test them before they send them out.

yea changed fuel filter and FPR, and I checked the pressure using the schradar valve and it leaks back down into the tank. Im guessing the checkball in the fuel pump is done. i have to prime the car twice to get it to start and it stumbles at idle but other than that it works fine. Im going on a long distance trip soon so i'd like to make sure i have a good fuel pump so I dont get stranded

So how the h*ll do you remove the vent hose from the fuel pump? its the only one that is not a quick disconnect and no matter what I did it would not come off. I ended up breaking one I was trying to pull at a yard and dont want that to happen when doing mine

check to make sure your fuel rails aren't leaking at the engine. When I had my car at the dealer they recommended replacing the fuel rail assembly thing. It might be possible that you have a leak in/at the fuel rails like I did.

I was thinking that as well but the issues first started when I filled up with some arco gas, then my fuel sender was acting dumb and getting stuck, my fuel pressure regulator went bad, and I was having hard starts when cold. I ran a few bottles of techron through, replaced the fuel filter and changed the FPR and my fuel gauge started working fine but I was still having hard starts. Since its still not holding pressure im pretty sure its the pump. bought a delphi yesterday from amazon for $210 - $50 i got for getting there credit card that I was planning on getting anyways, so it should be getting here soon.

I replaced with delphi about 2 years ago... Needed to be spliced into harness (shop did it) but no problems so far.

So finally go around to replacing my fuel pump with a new delphi one, and still not holding pressure and having trouble starting cold, the car was fine before the FPR went out and I started smelling gas thru the vents. Can it be the FPR itself?

its not leaking thru the top like the old one was.
