Fuel pump not running no pressure. Just replaced pump. Ok, checked all of the fuses in the whole car (under hood, in rear electronic module, central electronic module) checked the relays under the hood (they all can be triggered with a 12v power supply), if I take out the fuel pump relay and put key in 2nd position, I get 10v on the 2 switched leads, I did the old 'paperclip' between the 2 leads to simulate the circuit being triggered (no fuel pump on). Not sure what to do next.

Do you

Are you getting battery voltage at the fuel pump when the relay terminal are jumped?

If voltage is available, check the ground circuit connections.

Also check the fuel pump module behinde the right rear wheel well. Check connectors for oxidation especially if you live in the east coast? If that is corroded you will need to replace the module with the harness and actually the repair has you put it inside the vehicle now. Let us know what you find?

Behind the right wheel well. What pieces do I need to remove to check it? What does it look like? I do live in Chicago so corrosion might be an issue. And when you talk about the right side, is this driver side or other? (Sorta like stage left or right. Heh)

Remove the rear passenger wheel. Towards the front of the wheel gently pull back on the wheel well. You may need to drill out a rivet or 2 but you may get lucky where you will not need too? But once you pull back the module will be sitting right there. Let me know if this helps you out?
