So if your not getting any fuel, check the fuel pump and the fuses for the fuel pump. Sounds like the fuel pump probably slowly crapped out

Yeah I did some research and The car has two fuel pumps. One inline and one intank. Prior to the idle issues I heard this bad whining noise underneath me. And the night before last it had stopped when i pulled in the driveway. That next morning it wouldnt start. So I am assuming that the one inline crapped out on me. Im going to replace it and see what happens. Thanks for everybodys help.

If you need to take it somewhere, take it to rwturbo, great standup guy, VOlvo specialist, and he'll be cheaper than A Volvostore, although Volvostore does excellent work also.

Inline pump is likely.

If you could hear it pretty good it was most likely the in tank one. Call Tom up man they are pretty cheap.

I heard the whining noise through the center console area. Thats where the inline pump is.

So if the inline pump dies, the car wont run at all?? Could the intank still be good??

Hey geonfreaq, can i get part numbers and prices for both pumps??? thanks

Thanks I appreciate that. I am replacing both. I figured the inline pump went bad becuase of the intank pump being bad also. Thanks again.

Most likely your inline pump. Replace that first before you go through the hassle of replacing the intank one. It's possible for one of these cars to run with only the inline pump working.
