2011 Hyundai Tucson Fuel System Diesel Problems

Your fuel pump failed after only 40,000 miles—far shorter than the typical 100,000-200,000 mile lifespan—leaving your car unable to start. The dealer initially misdiagnosed the problem as a faulty starter, costing you unnecessary repairs, before eventually determining the fuel pump had an intermittent electrical short. You're concerned about whether the pump was defective, installed incorrectly, or damaged by faulty wiring, and you question the dealer's diagnostic accuracy and service reliability. Fixing this will likely require fuel pump replacement and inspection of the fuel system wiring and connections.
