I think I've traced this to a dead fuel pump.

I put a rag under the fuel rail test port and depressed the pin, and no fuel came out.

I pulled the fuel pump relay, jumpered pin 87 and 15 and put a voltmeter on it - I had power here.

I took all the interior floor panels out and opened the access ports. I have a new fuel filter and have been trying to find time to do the swap, so I figured now was as good a time as any and pulled the lines off the old fuel filter. Almost no fuel came out, and what little fuel did come out had no pressure - it was just fuel running out of the filter canister.

I took my multimeter and checked for power at the connector at the rear of the car, and found I had power there too.

I put a hose of the pump-side filter hose and directed it to a catch bucket and then turned the key on and even cranked the engine a bit - no fuel came out of the hose.

I built a jumper from the pos battery terminal to the fuel pump plug and grounded the other side, and again the pump did not run and no fuel came out.

I don't know what else to do in order to prove that it's the fuel pump but I feel reasonably convinced at this point.

Any advice on this would be helpful.


My next question is, how hard is it to change the fuel pump? My car is an AWD and I suspect that complicates things a great deal.

If there are any docs on how to do this I would love to see them.
