Not getting power to the ignition.

start with the simple stuff ~ are the battery terminals clean and making good contact with positive and negative cables? Are all of your connections solid? Have you tried to "hot start" the car ~ run a wire directly from the power side of the solenoid to the starter side? Two replies have mentioned the neutral safety switch ~ have you checked it and verified that it's wired properly and not loose?
Yea, a volt meter is a good idea.
