Postby farleyj on Sun Feb 03, 2013 7:40 pm

Mite b a stupid question but here it goes. Got a dodgy engine bay loom. Checked the injectors for power and seem to be geting 2 live wires when ignition is on. Is this right? Looked in haynes manual at wiring diagrams but ive got no clue on electrics. Any help wud be great.

Depends.

If it's batch (semi-sequential) injection then you might find you have two permanent lives and the injectors are fired by switching negative.

What car / engine / management is it ?
Nothing to see here...

Yes,you have +12V on turning the key,and the ecu sends the ground to the injectors in pairs.1-3,4-2.
