THE CAR FUEL SYSTEM IS TOTALLY MESSED UP, WILL ONLY FILL A HALF TANK AND RUNS OUT OF GAS BECAUSE THE FUEL TANK SYSTEM IS NOT WORKING CORRECTLY. CAR WILL NOT FILL. ONLY ONE TANK TAKING AND SENDING FUEL APPARENTLY. DASH IS MESSED UP, LIGHTS OUT, FUEL SYSTEM TOTALLY MESSED UP.

NO GAS, NO POWER, MY CAR WENT BACKWARDS, BRAKES NOT WORKING, I WENT INTO A DITCH AND ALMOST INTO A STEEP HILLSIDE, VERY SCARY.
