    If you aren't getting a ground signal on pin 85, swap ECUs first.

    CPS won't kill fuel at all.

    Closing SOON!

        I will not be near the car until tomorrow, but it looks like it is either the CPS or the spark sensor. I will check the CPS for an AC Voltage(generated by the sensor being flagged), but in my case, the most likely issue is wiring in the harness to the ECU.
        If you are having the same problem, you should verify that your CPS is working properly first. What are your symptoms?

          car will start and idle normally until it runs out of fuel
          apparently the initial pressurization of the system is normal, starts normal, but the fuel pump does not run afterwards.
