My 87' Iroc-z (305-5 Speed) has no spark. I have found that I have no tach signal from the white wire on the gray connector on my coil. I traced it all the way back to the connection on the back of my tach. I have power P/B wire, and a good ground B wire. So my question is: can a bad tach solid state component be the cause of all my problems?
Thanks for any response!
P.S. All other ingnition components have been replaced, fuses are also good!
