2004 chevy Silverado had a bad fuel pump. Consumer thinks that GMC should have a better quality fuel pump.
2004 Chevrolet Silverado stalled, and died, the engine warning light came on, and the message center on the dash read " reduced engine power". The truck would not restart and steering and braking was limited. The consumer pulled off the road and checked under the hood for signs of failure, none were found. The vehicle as restarted but it had no power, idled roughly and would go no faster than 3-5 mph. This problem recurred two more times. The problem was diagnosed at the dealer with a throttle actuator code, the throttle was replaced. The dealer believed the problem was with the fuel pump module because he had replaced several on similar vehicle, but since the code didn't come up during diagnostic he was unsure. The consumer mention a service bulletin (document id 1538353, #pip3022a- dated July 19, 2004) which the dealer was aware of. The consumer had the dealer remove the tank and indeed the fuel pump module on the truck had the same part number mentioned in the service bulletin. The manufacturer has refused any financial assistance.
