ECU or Injector probs???

[blues n 2s]

The black/blue wire side of the injectors is 12v when the ignition is on. You should also see 12V at the MAF supply as well here.

This is achieved by the ECU holding relay until the fuel pump relay activates to take the load when engine is running.

This black/blue wire must be fused though

ok cheers paul.size fuse you reckon??will get this checked an done.look forward to your permanant repair guide.Thanks again mate
