Gonna see if you guys and gals out there can help with a little problem that I am having with my ignition. First I will start with the mods and all the new parts. Brand new 347 stroker, new starter, alternator, voltage reg, starter solenoid, battery, painless wiring, msd pro billet distributor, blaster 2 coil, 6a box. Please bare with me as i explain this problem. When i turn the key to start the enigne, it turns over with no spark. When i release the key from the start position and it moves to the on position, thats when it throws a spark. I have pulled the coil wire to the distributor to verify this. The engine will eventually start, by doing this cycle a couple of times. Has anyone ran into this before? I'm thinking that maybe the ignition switch is bad and the contact points are worn. Thanks for the help.
