The car runs off an emerald K3 standalone Ecu not the vw item. It uses a common ground on the -ve and a pulsed 12v signal to energise the injector coil. I'm not sure if it has 12v at pre crank for a small ammount of time though, i don't think it does though.

When it turns up tomorrow I'll check it all out again, this is very strange. So that red wire has two functions? To see 12v at the injector and the to sense the pulse to work out the duty??

Thinking about it, I won't have 12v at the injector at pre crank as the fuel pump primes when the door opens, if 12v was applied then it would inject fuel.

How can we get round this??
