ecm not supplying the ground. be carefull powering lamps with injector power/ground since the ecm is there up in the mix. common cause of ecm cutting injectors would be a bad dist but then you would have no spark too. i would reccomend swapping ecms and see if that helps at all. do you have access to another ecm to try?

yeah computer/ecm. it is easy to get to. pass side kick panel is the only thing in front of it. many things are interchangable between cars but not engine stuff like ecm.
