Air in fuel lines.

[DEV0 E30]

My fuel system doesn't have enough pressure.
Fuel Pumps have both been replaced only months ago.
The car has been sitting and last time it sat it did the same thing.
Didn't want to start, but somehow it cured itself.
I'd like to know if anyone has some creative ideas to build up the pressure.

I'll probably just keep filling it up with fuel to decrease the amount of space the air has in the tank and whatnot but anyone have any ideas where I can get a cheap fuel pump or something?

How much pressure does it make?
Maybe a hole in the lines in the tank.
Regulator problem?

Insufficent.
My next door neighbor who has a sytem to check isn't home.
No leaks, I fixed the only one.
Please no.

I has nothing to do with air in the fuel tank... For it to suck air: Your intank pump would have to be out (assuming you have a car that has two pumps - pre 88 or so), or you'd have to be out of gas.

To me it sounds like a fuel pressure regulator problem. A cheap (get a used one from someone here) and easy fix. It's on the front of the fuel rail with a fuel hose hooked up to it and a vacuum line hooked up to the other end. To pull it, remove the two 10mm nuts after you get rid of pressure in the fuel system. To relieve pressure, if the car is able to run, pull the fuel pump fuse or relay while the car is on and let it stumble and die.

If the pumps are new, it could also be a crimped fuel line. Check over them carefully along the bottom of the car as a misplaced jack can close the lines up.

I replaced both fuel pumps shortly after I bought the car. They are under 6 months old so I'm hoping that they are still doing their job.

Yeah I was checking prices earlier and didn't like what I saw for such a small part. Getting one used. This board rocks for saving money, love that.

I don't think it's the metal lines, I'm pretty careful jacking it up.

In a few days I'll know if the new regulator fixes the problem.

Thanks guys.

It would be nice to know how much pressure you have, and run some checks before throwing parts at it.

Put a gauge on it, and crimp the return line a little and see if the pressure rises.

I'll do that tommorrow.
