318 no start after sitting

Here's what I'd do...........as I said go to MSD and download the MSD destructions for everything you have hooked up.

Get a good hot spark established FIRST

I assume this was running OK at one time so everything is wired right, right?

The tach signal on an MSD is NOT off the coil NEG so this means that just because the tach works does not mean the ignition system is OK


It could be a bad coil or even a coil wire. I like to check for spark with a grounded probe held near the coil tower, as that eliminates a bad coil wire.

I won't be a heck of a lot more help as I don't use MSD products.
