    Suggest you try another mechanic. You dont give us much information but I doubt 3 fuel pumps are what is wrong.

    I knew I'd read it somewhere....

    A very common reason for multiple fuel pump failure is too high of a voltage drop in the line supplying power to the pump. Have your mechanic check for a voltage drop to the pump. The issue is because it is not getting the voltage required it continues to draw high amps and burns out the pumps.I hope this helps.

    Assuming that the fuel pumps being purchased are of good quality, the most likely reason for the repeated failures is a faulty fuel pump relay. A defective relay can cause a fuel pump to short out. It is located in the under dash driverís side fuse box. Have it checked and if there is the slightest doubt have it replaced.

    Excuse the off-site link. Only feel it's fair to source it.
