Six problems related to fuel pump have been reported for the 2003 Chevrolet Suburban. The most recently reported issues are listed below.
The fuel pump on my 2003 Chevrolet Suburban has failed. It seems that this has been a problem with these vehicles in the past. I wish I had known before. I bought the car used in 2005, with approximately 32,000 miles on it. The "throttle body module", "steering gear", dash cluster, and now fuel pump have all failed! this has made me very upset with the manufacturer. The vehicle now has 72,000 miles on it. I thought buying american was the right thing to do. Now I'm worried about my 2004 GMC sierra.
Before complete failure, over a period of a month the car failed to start/turnover. After 5 minutes & repeated attempts car would finally start. On final failure date, the car would not start even with periodic attempts over 2 days. Vehicle was towed to dealer. Dealer replaced fuel pump & fuel filter which seems to have fixed the problem.
The contact stated the fuel tank collapsed, crushing the fuel pump, which has been replaced twice. The fuel tank was plastic. The vent to the fuel tank was blocked and caused a vacuum which crushed the fuel pump. The first time, the vehicle was driven at 45 mph, it shut down without warning and would not restart. An indicator light illuminated, stating the computer shut down the vehicle. The vehicle was towed to the dealership, and the fuel pump was replaced. Less than three months later while driving, the problem recurred. The vehicle was taken back to the dealership. The fuel pump was replaced a second time, and the vent for the fuel tank was retro fitted to the engine compartment. The vehicle has not had any more problems.
