You know one thing I did not think of (since the battery is in the trunk) was possibility of voltage lost at the coil. Have everything connected like you were going to start it except the wire going to the coil '+' Hook this up to a voltmeter. Actually it can still be connected since the motor won't start.

What is the voltage when the motor is cranking?

If it drops below 9 volts while actually cranking then there is a good chance there is not enough voltage to power the MSD. I cannot remember the voltage required to power a MSD, but I think it was 8.7 and up?

Allen Here's a novel idea, let's not throw a bunch of parts at the car hoping it will fix the problem and instead spend a little time diagnosing it first. Life was a little easier when I was just a wrench.
