I was out and about today and i noticed my check engine light came on. There were no drivability problems. I headed home and about 3 blocks away from there the car just cut off. I could restart it immediatley, and it would run fine for a few seconds, then stumble and cut off agian. I went home and got a scanner which said code PO171 (lean bank) and a fuel pressure tester. My pressure was 45PSi or so when i turned the key on, and it would hold that value I'll say indefinately. When I started the car the pressure began to plumet until the the engine just would not run any longer. Since I have 257K mi, I figured that looked like a fuel filter. I put a new filter in it on the side of the road, but that did not change anything. I ended up figureing if i started it and put it in gear, I could drive a hundred feet or so before it would cut off, so I drove it all the way home by doing this.
Once home i see that there is some kind of stuff in the relay panel that says "fuel pump sence". What is that all about? Does this thing have an independant speed controller on it? If I need to put a new pump in , I'll do it, but I want to make sure Im not overlooking anything.
Suggestions? I have a meter and am competant with it, so if there are some signals you recommend I check let me know.
Thanks
Shawn
BTW, how do you get the tank out? it looks like a major PITA with the rear suspenstion crossbrace thing in the way of the fuel tank connections. any tips?
