2004 Chevrolet Express 2500 ProblemsCheck Engine Light and Misfire Due to One or More Stuck Closed Fuel Injectors
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 fuel pump may fail causing the engine to stall and not restart.
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.

2004 Chevrolet Express 2500 RecallsFuel Leak Due to Corrosion in Area Near Gas Cap
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.
On two vehicles, the high mount (third) brake lens may not reflect enough light to meet Federal standards. Following vehicles may not adequately see the brake lamps, increasing the risk of a rear-end crash. Quality Coaches is working with Audiovox to replace the center high-mounted brake lamp assembly. The recall began November 23, 2005. The Quality/ASA recall number is VCCBLCHV.
