Car cranks but will not turn over. After testing things found that the fuel pump was not getting power when the ignition switch is turned. Ran a direct wire to the fuel pump and the car will run that way. I have looked everywhere for diagrams to see where the relays are if it's a bad relay. I can't find the location of them. If it's not a relay, what else could cause the fuel pump to get no power?

Hello,

The information that you requested is in the diagrams down below. I have included the Engine Performance wiring diagrams with the fuel pump circuit highlighted for you, as well as the diagrams for the fuses and relays along with callouts. Please go through these guides and get back to us with what you are able to find out.

Thanks,

We thought that maybe it was the crankshaft position sensor, I ordered a new one but still having the same issue. I found a box under the passenger seat, and when my friend put power to it the fuel pump turned on. Does anyone know what this box is and how does it connect to the fuel pump? At this point we are thinking that it's the ECM that's failing to start the fuel pump. Has anyone ran into this problem or know of anything else that can cause a fuel pump to get no power? Fuses are good, and the car turns over when a direct wire is put to the pump. It's looking like it's dead wire (no power) from the fuse to the back seat where the pump is located.
