What the heck it wrong with our 2002 Pontiac Sunfire?
Our 2002 Pontiac Sunfire died on the highway. Husband started it back up and drove
another couple miles before it died again. This time it would turn over but not start. Towed
it home and mechanic hooked the code reader up to it. Says needs fuel pump. Replaced
the fuel pump and still won't run well. All of a sudden, misfire on two cylinders! This car
ran perfectly before the fuel pump went out! So code reader again. Getting a P0300 and
a U-1040 code. Changed plugs and still no power. Husband is ready to get rid of it! I'm
not so sure it's that serious. Can anyone help with this? It's the 2.4 liter.
