Ron,

Before you spend alot of time on this.......have you talked to other "Z" owners to see what they did about the issue. Their has got to be more Z guys out there that have had to overcome the same issue......and.......

When you say it will not start, does that mean it turns over, but does not light up? Because if it turns over and does not fire, thats a good indication its ignition related. If it does not turn over, I would make sure that you are getting 12V to the starter. Could your + cable be corroded on the inside, creating resistance that would prevent it from getting 12V to the starter?

Any which way....good luck, and hope you find an answer to get 'R done.
