1963 MSD Ignition Box no spark?

[Ellobo53]

My 1963 Thunder bird is running an MSD Ignition-6A box. Don’t know why (Car was Bought 3 months ago) had the car running to warm up, it started to shut down like when running out of gas, I put in some gas and it will not start, I check the coil and spark plug wire to spark in either one. First question any ideas on how to diagnose and fix? Second question do I really need the MSD setup? Thank you all for your advice.

MSD ignition system is a good system. If you have spark, I would guess a fuel problem. Check for fuel in carburetor

Hello this is Benicio, Sorry miss typed. I meant to say that I checked the coil and spark plug wire to spark. No spark in either one.

I would start by checking to make sure you have power to the coil and msd.

Benicio, you can find wiring diagrams for the MSD 6AL boxes online. I believe the red wire input to the MSD should be receiving 12v for the system to work. If it isn't, then possible culprits include the ignition switch or the power wire from the ignition switch to the ignition.

Thank you all who responded. so after a few days of doing reading and research, I started by checking to make sure I had at the MSD box then went to the coil. the problem was a bad coil.
