HI and thanks for using 2CarPros. Com.
It sounds like you are correct. It is not getting fuel. I am not sure what wire you cut which sparked. If the ignition was off, there should not have been power to the oil pressure switch.
Since you have already confirmed it's not getting fuel, lets start easy. I have attached a engine compartment view of the vehicle. I need you to first locate C-9. Take a look at the picture for location. This fuse is for the fuel pump and ECM. You may have blown it when you shorted the wiring.
Next, the fuel pump relay can be an issue. However, I question that it could have been damaged. Here are directions for replacement as well as location and pictures.
Note: The fuel pump relay is located in the engine compartment, attached to the multi-use bracket on the upper dash panel extension. Other than checking for loose connections the only service on the fuel pump relay is replacement.
Verify that the ignition switch is in the "off" position.
Disconnect the wiring harness plug.
Remove the fuel pump relay.
Install the new fuel pump relay.
Connect the wiring harness plug securely.
Lets start with that for now. I have a feeling the fuse for the ECM/fuel pump blew.
Let me know what you find or if you have other questions.
