Thanks, I will try that out.
I have just checked the pump flow rate, it looks just fine 12 Oz a min at 2.0V and proportionally less at reduced voltages.
I noticed that the pump V was at 2.6V on the last attempt, which is way too high, so there is a pump voltage to RPM mismatch which is causing the fuel fail warning.
I will try my other P-60 ECU tomorrow.
Need to keep it quiet for mothers day.
