I don't know liter size of engine, it may not matter? Generally on this model year. There is fuel pump oil pressure switch that is parallel to fuel pump relay, either one could possibly run your fuel pump. The fuel pump relay and inline fuse may be on your firewall. The picture shows location of fuel pump relay and inline fuse, check them both. I hope my database is correct? If you want diagram for fuel pump relay to check relay circuits, I'll post it?


hope it helps
