2003 Chevrolet Express 1500 Problems
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.
One or more fuel injectors may become stuck closed causing an engine misfire and the Check Engine Light to illuminate. Our technicians tell us that this problem can be caused by some fuel additives. There are special procedures which may be able to restore the affected injector. If this fails the affected injector must be replaced.
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.

2003 Chevrolet Express 1500 Recalls
On vehicles equipped with a left side cargo door, water and road contaminants may become trapped in the protective conduit that covers the fuel filler pipe, which can cause the pipe to corrode. Significant corrosion may allow fuel to leak during refueling, and in the presence of an ignition source, this could cause a fire. Dealers will install a new fuel filler neck to correct this concern. The General Motors recall number is 12166.
On certain vans, the front and rear seat belts will not latch or unlatch. In a crash, the risk of injury is increased if the seat occupant is not properly restrained. Dealers will inspect the seat belt buckles, and will replace the buckle assembly if the buckle is found to be inoperative. If the buckle is found to function, only the upper buckle cover will be replaced. The recall began March 15, 2006. The GM recall number is 05113.
