04 Silverado just recently did heads intake and upgraded to 80 lb injectors. Now im throwing this P0200 "Injector Control Circuit". I have gone through and triple
checked to make sure everything is plugged in. The new injectors are ev2 so I have the hard plug adaptors. I have put the ohm meter on all the injectors and they all read the same. So im not thinking its an injector. Wondering what the next step to isolating this issue would be? I found a pid GMINJECTOR1-8 looks like it
could help but Im not sure of the prerequisite pids to be able to select this?
