Recently, installed a new camshaft new lifters. Also, the MSD control solenoids made sure all deposits were removed from motor had a failed new lifter, which I replaced. Now, I have no signal from computer to some of the coils did not crush harness, but there is an open between coil connection and computer. So I need the pin out Diagram for the e c m... I have looked online and cannot find the correct diagram. And my closest dealer is 50 miles away. Misfire, on cylinder six and eight, and I require the proper e.C.M diagram to check for continuity to ignition coils. Thank you very much robert taylor
