New pump fitted tonight but still not starting or priming. Have got fuel coming out the filter so pump must be working that far at least but don't think its coming out of the injector pipes at the metering head.

Am pretty sure I have spark but difficult to tell when by yourself. I did also try weighing the flap down on the metering unit using a heay socket to hold it open while I cranked it over and still not starting.

I checked to make sure the correct plug was on the auxiliary air valve too as the red/black wire from there feeds to the pump too and that was fine.

Is there anything else I can check? Will go and get a multimeter tomorrow to help.
