On the stock car it would get cranky when hot. I started cranking it THEN switching on the ign while cranking & that took care of it. Ground your coil wire & try it & see if that takes care of it
Can you explain what coil wire do you ground?
the large coil to dist wire, I hold the dist end 1/4" from the intake or similar ground & have someone crank it. pulling the ECU pentastar connector will do the same thing, then crank it EDIT seperating the dist pickup zigzag connector would be the easiest & no helper needed if seperating one of these connectors
