Would anyone know what the symptems are of a bad fuel pump or fuel sending unit? I am still having problems with my 99 Rodeo. I still get the surging sometimes on start up and I suspect that my fuel guage isnt reading correctly. Gas mileage is still down and so far no more CEL's except for the once after i replaced the back 02 senosrs. It came up with a code for bank 1 system lean. Cleared the code and it hasnt come back on yet.(knock on wood). Im going to be moving long distance in a week and was concerned about being stuck in the middle of nowhere if my fuel pump or something dies. Thanks for the previous help.
