Ok, so I just checked it out this morning, plugged at all back in for system initialisation, grey harness, red to injector +ve and green to injector -ve which seems to be always earthed. Turn the key to position 1 of 2 (pre crank) and on getting nothing at all, I'm assuming that's because I don't have any power at injector +ve at pre crank as expected.

Bit stuck as to what to do now.... I assume the way the the hfs-3 is set up is that it uses the -ve to sense the duty, as the +ve is constantly powered?

Richard, I'll give you a call later on today, it's better to talk about this over tue phone I think.
