Injectors not firing

Recommended Posts

Hi, got a xtreme G4 ecu and a 1uzfe engine on sequential injection. One of the issues is that left bank 1,3,5,7 didn't fire when in injector test. 2,4,6 and 8 were fine. Then injector 1 started to work the only one on that bank.  All injector have power, any ideas.

 

Thanks

 

Steve

You could swap the injector output pins at the ECU, this will confirm if the fault lies in the ECU (hardware, firmware, or base-map) or if the fault lies beyond this in the wiring or injectors themselves.
