Man I've tried everything, it now has a new wiring harness, new ecu, new relay box (all USA)....there is no F1 flashing fault codes, I have checked input voltages on most of the ecu pins (fall over switch, butterfly valve, throttle sensors etc etc).
The damn thing turns over fine but the fuel pump isn't going through it's priming cycle....
Any ideas to what could of failed for the ecu not to send the required signal to the fuel pump relay...
