I have been having ingition trouble with my 67 302 coupe. It has a MSD ignition. 6AL box,Billet Distributor & Blaster 3 coil. The problem is I can start it but even if I only run the engine for 30 seconds it will not restart right after I shut it off. If I let it sit for a while it will start. I called MSD. They said It was either the coil or the pick up. I bought a new MSD Blaster 3 coil and checked the pick up per MSD intructions and it still will not restart immediatly after shutting it off. I also checked the ignition switch. Everone I asked is bewildered. Any Ideas?
