I did sand the back of the ecu really good and I took all my grounds off and sanded them and tightened them down. I'm setting here reading my fsm trying to figure this out I have a bunch of electrical issues . I think most of it is me not knowing wtf I'm doing! I hate electrical i suck at it in an absolute retard when it comes to wiring. I have tried to learn I just don't get it. I have voltage now when I check the positive side with a known ground like the battery post. But not when I check both sides of the coil pos to post neg to neg! Is that normal?
