i have a nasty problem my injector 3 is constantly running when the ignition is on... very strange i have 12v at the connector for the injector, but if i test pin 33 and earth at the ecu i dont get 12v showing the fault. do the injector wires route straight to the ecu?

cheers

 

the injectors do run a constant live, its controlled by earth pal iirc


so the problem could be a broken wire going to ground, disconnect the ecu and run a continuity check on the feeds, and see if and where it goes to ground

otherwise you may have an ecu injector driver issue

 

i think it must be a broken wire some where as i don't have a reading the same both ends...

what a night mare pulling the whole loom out...

 

na, its piss easy man

 

check the wiring where it goes through the bulkhead mate, my grommet had been pulled out on a previous sapph and rubbed through casing permanent earth and masses and masses of fuel being dumped in cylinder 3.
