ey, how can you tell if the fuel pump is bad? my car has 120k on it and it has been sitting for about 1 1/2 years. i got it running with a b18b swap. and it sputters and bogs only on low rpms, it also back fires a little. but at high rpms at wot it seems just fine. im thinking its the o2 sencor or fuel pump, any tests i can do to check if my pump is bad? thanks
