Hello there. First how did you determine that there is no power to the pump? I this is true first check the fuse there is a fuse in the fuse box just for the pump. That would be great if that were the case and is usually what the problem is. If you check the fuse and it is good the next thing to do would be to check for power at the fuse with the key turned on. the power to the fuel pump is on only when the key is turned on this completes the circut. Asside from theas two things you will need to follow the harness from the fuse box to the fuel pump to check for breaks. Hope this helps. Blown fuse, bad fuel pump relay, disconnected or broken wiring, and in rare instances, a defective computer.
