I would start at the fuel pump relay with a wiring diagram to see if that is functioning correctly., getting power from DME relay, etc. Easy to bypass the relay and force the fuel pump to run as a troubleshooting step.
In my lack of brilliance I had the fuel supply and the fuel return backwards on my M50 fuel rail which was keeping my conversion from starting. That was found after spending lots of time troubleshooting the electronics which were all fine. |
