2001 Chevrolet Express 3500 ProblemsFuel Level Sensor Failure
It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.
The tail light wiring harness in the cargo area is not protected very well. As a result it may become damaged due to normal wear a tear. This damage can causing some or all of the rear lights to stop working.
A coolant leak may develop from the water pump. This can result in an engine overheating condition. A leaking water pump will require replacement.
2001 Chevrolet Express 3500 QuestionsWhat else can I do for a p0300 code? (2 answers)
I have changed fuel filter, air filter, plugs, wires, distributor cap, rotor x 2, ignition coil, cam shaft position sensor, crankshaft position sensor, and radiator. I am not showing correct temperature on the gauge but that is the only other issue. I have also changed the radiator and oil cooler...
My exhaust starts off quiet and all of a sudden gets loud and looses a little power and check engine light comes on. Then goes back to normal then gets loud again and so on???? Please HELP!!!!
The gauge will move very little as the engine warms up. It actually stops at about 170.
