Hi,

There is a chance the pump has failed. However, where is what needs done to confirm. First, you mentioned the fuse is good. In addition to checking the fuse, confirm there is power to and from it. Here is a link you may find helpful:

If the fuse is good and has power, check the fuel pump relay under the hood in the fuse box. If you look below at pics 1 and 2, they show the location. If there is another relay with the same part number, switch them. If there isn't, here is a link showing how to test a relay:

If the relay is good, then we need to go to the fuel pump. There is a pink wire that powers the pump motor. At the top of the fuel tank, where the pump module is located, find the pink wire and check for power to it. If there is, locate the black wire and check it for continuity to ground. If the ground is good and you have power to it, chances are the pump is bad.

If you determine the pump is the likely issue, here is a link showing how in general one is replaced. Use this as a guide.

To replace the pump in your vehicle, there is a service port in the floor to access it without removing the tank. However, you will need to remove one of the seats.

The remaining pics below show how to access the service port, and remove and replace the pump.

Let me know if this helps or if you have other questions.

Take care,

Joe
