I have a 2005 S40 T5 FWD. The other day it died on my while driving, no sign of any problems the engine just quickly and smoothly lost power. It gave me a "Reduced Engine Performance" message on the dash. I had to call a tow truck and while waiting for the truck I tried starting it a few times and it did fire once but barely, it was almost running like it lost a cylinder and I shut it down after about 2-3 seconds. After I got it home I checked the Schrader valve to see if it has pressure and no gas came out and I could hear the pump turn on. Next I checked the fuel pump fuse and it was bad so I replaced it and tried starting the engine and nothing, checked the same fuse and it was fine. I borrowed a scan tool from a friend and it came up with 3 codes but I accidentally erased them
and only got to see one code which was for an O2 sensor bank 1. About a year ago I replaced the fuel pressure sensor so I don't think its that.
I really don't want to drop my fuel tank just to find out that its not the fuel pump, is there any other things I can do to narrow down my problem? Also there are two possible fuel pumps I would need, one is $300 the other is $1,500! Other than removing the pump how do I know which one I need?
