Crazy K Posted January 18, 2007 Report Share Posted January 18, 2007 my 93 vert has a run rough, no start hot condition. When it won't start it cranks but the tach won't move. Not the PCM, CPS, or ICM! Check the wiring between the ICM and CPS? Mine will do this occasionally and it's because the wiring is shit. yep done that too. it even has fire when it cranks. I'm doing fuel injectros next, hoping that is it. Quote Link to comment Share on other sites More sharing options...
