FIRST AFTER NUMEROUS ATTEMPTS OF PUTTING UNIT ON DIAGNOSTIC SYSTEM. IT WAS DETERMINED - WILL FIRST THE COMPUTER COULD NOT READ MY CODES; THEN MY MECHANIC DETERMINED IT WAS FROM THE FUEL SENSOR. CHECK ENGINE LIGHT IS ON. REPLACED FUEL PUMP FOR 450.00 AND CHECK ENGINE LIGHT STILL ON AND FUEL GAUGE IS INOPERABLE. I CAN NOT PASS INSPECTION DUE TO MY ENGINE LIGHT IS ON.
