power is the dark green/light green. it powers the coils and injectors. common power through fuse 14.
jump the asd relay. then check direct to ground with meter,test light, whatever.
then you'll have to test continuity, as adpros said, between the computer plug and the plug at the suspected injector. (went back to post 1. done already i guess)
ground could come back through the heated O2 sensors on the power side, as they are on the same circuit. so, if you didn't jump the asd relay,you wouldn't have +12v.
so, yes, probably bad pcm driver.
