Hi Kevin,
Hope your staying safe!
I have physically pulled the loom, fuses apart and checked plus load tested.
Was beginning to doubt myself so jumped straight in.
I suspect the Engine Ecu has shut down as I am only seeing under 2 volts at the injector common feed, that's why I wondered about the power relay.
I am using a T5 workshop manual in combination with autovista and info from the net including Ross Tech etc.
Having had another deeper look today it appears the injector wiring loom maybe slightly offset to the harness plug so will strip that out again. It doesnt make sense as it drove for about 50 odd miles with it like that, wondering if it may have just made enough contact to run but gave up despite the connector clicking fully home? Worth a look anyway, from what I can make out if the ECU sees incorrect signals, resistances back from the injectors it will shut them all down? I will then have to do a pin out test at the ECU hoping I have the correct info.
Thanks
