Okay folks, I have an issue with my truck. Used to run fine, and then it just doesn't hardly run at all now. In fact, just now, I couldn't get it cranked.
Anyway, I have a 302 with a Mallory HyFire 6A, and a Mallory Unilite 37-series distributor...no vacuum advance--all electronic. So, I know I'm getting power from the control module and ignition to the distributor (test light), and I'm getting fire from the coil, but I'm not getting any spark at the spark plug wires. I've tried multiple wires, and it doesn't spark with any of them.
I figured the cap and rotor was bad. The timing wouldn't affect the spark would it? I haven't moved any engine parts around, so timing should be okay. I know that before I parked my truck...it was hard to start, but started. I drove it 10 miles and parked it. I worked on it for about two weeks, and then tried to start it to move it, and it won't run. I checked for fire, and the above description is what I got--nothing. I decided not to check for fuel...could smell it. LOL
You just put in a wiring harness. Start looking there.
My best advice to you is ohm your coil and see if it is still good. Then if so I would disconect the MSD box and run the distributor straight to the coil.
People knock me alot for using the points distributor. I got a pertronix in them. However there are only two wires to hook up and 5 parts to break.
Unless your racing the fancy ignition setup is generaly a waste. Duraspark would have been fine save the cool factor.

Distributor cap and rotor?
