Team HOTHOT!
I was under the impression that on the L1 ECU loom the "power" feed for the injectors came from the fuel pump relay and then the injectors are switched to earth by the ECU in order for them to fire.......
Might be worth looking for your 12 volts and work from there........

Infact, looking at wiring diagrams, all the cossie wiring looms are like this - 12 volt feed from the fuel pump relay once the ignition is on......

when you first click the ignition on the led i put in injector socket lights up but then it goes off ,so you say the best place to check is the fuel pump relay.
can you tell me where i can find such relay?
could this also be a bad earth?
as the fuel pump is priming?
ive ordered a new tdc/phase sensor today from matt lewis so when they get here im gonna whack them on gap them properly and see how it goes.
