I drive a 98' Jetta with 91,000 miles on it. I went around a turn and my car died out. I replaced the fuse for my fuel pump and it ran for a block and popped. I replaced the fuel pump and filter and the problem still occurs. It runs fine at an idle but once i start driving, the fuse pops again.....any suggestions?

Thanks for the donation, It is appreciated!

What size engine?

Sounds like there is a short in the fuel pump circuit.

I may not be much help, but there should be some on the way.

I would look at the circuit as mentioned by Service Writer. Now the question is where the circuit runs through the car. What would I do?

I would run a new positive wire to the rear of the car and cut the supply power and hook to the new wire. If the car works fine and it eliminates the problem I would either leave it or test the wire to start narrowing down the location of the short. This is a short.

Suggested Repair

Inspect the fuel pump circuit for a short. Run a new positive supply wire to the rear, disconnect the original supply, and power the pump with the new wire. If the fuse no longer pops, the original wiring is shorted and can be repaired or the new wire left in place.

Conversation Summary

The owner of a 1998 Volkswagen Jetta said the fuel pump fuse pops after driving, even after replacing the fuse, fuel pump, and filter. The car idles, but the fuse blows once underway. Experts said this indicates a short in the fuel pump circuit and suggested running a new positive wire to the rear to confirm and isolate it. The owner then asked where the fuel pump fuse is located, and that question was not answered.
