I was getting ready to go out earlier and warming up the Mach. After about 3-4 minutes it just died. It started right back up for about 1-2 minutes and then nothing. It cracks but no sign of firing. I drove it to work today without any sign of a problem.

I took off the coil wire from the distributor and put it near the fender while cranking and no spark. Where do I start testing?

Here's what I have: Mallory dist., Mallory coil (old one), MSD Ign. module (old one), everything else is stock, new battery, new alternator. I've got a couple manuals, but don't know if having the electric ignition changes the way you do some of the testing.

I'm mechanically inclined, not electrically.

Thanks for any guidance...

Maybe it's that photo sensor flashy thingy in the mallory distributor that I hear always goes out? If the mallory your running is a dual point , then undo the electric ignition stuff and try that. Check all the grounds from the 6al. Use a voltage meter on the positive wire running to the coil and make sure that it has power. Make sure distributor to - wire is very secure. Ive had problems with that. If you mean there is no spark comming from the coil, then try a new coil. Im sure you have got one laying around?? I dunno. Somebody should find your problem though. Im hoping the module didn't crap out. Good luck.

first off, on an MSD box, you don't test for spark that way. Take the coil wire off, set it a few inches from a ground. If you have the MSD hooked up with the white wire, then take the green and violet connector, and bride them together with another wire, once you un bridge them, a spark should jump from the coil wire. If you have it hooked up with the magnetic pickup (violet and green) then take the white wire and touch it to a ground. A spark should jump from the coil wire. Also, make sure the key is "ON". If you can't get spark, then the MSD box is to blame.
