“I bought this truck in 1997 and within 30 days the fuel pump went out.I took my truck to chevy land to have the pump replaced. This took over 3 weeks and we had to go threw about 4 or 5 pumps . I then went out and bought a brand new pump, not a rebuilt one and then it ran o.k for a short time and back to doing the same thing again. We took it back in again and the pump was bad again. …”
