    Adjusted the TPS back to where it was and the part throttle problem went away. Must be a wiring problem somewhere in the engine bay that caused my original issue.

    I pulled my crank sensor today and the insulator where the wires connect to it was gone. IDK if it melted or what, but the wires were damn near touching each other, so I'm sure it's possible that they were shorting potentially before it stopped working entirely. Hopefully I'll have it together tomorrow so I can see if the problem comes back or not.

    I put my car back together after the crank sensor and still no fuel. It's at the mechanic now for diagnosing. I'm starting to think I need to replace the entire wiring harness.

    I can say with almost complete certainty that your problem was the knock sensor wiring...

    I finally fixed mine yesterday. When I logged there was no knock sensor voltage. I pulled everything apart and tested the knock sensor wiring with a multi-meter and confirmed it was all good. Plugged it all back in and knock voltage was working again and the car runs as it should.

    I had an issuse with 7-8-9 knock counts a while back, checked everything including connector for corrosion (everything ok) put it back together and never had a problem since either.
