msd 6a fault???

I have had 6a ignitions outlast cars. I have also seen a cracked coil tower kill 3 of them in a week.

If it ran good, then quit after it sat for a week, start looking for a high tension leak someplace.

Grab a spare plug wire & plug. Ground the plug body, and plug the wire into the coil. Test the ignition. You should have a very hot spark at that plug.

Watch the coil carefully when testing. If it arcs anyplace besides the gap in that plug, you have your leak.
