Engine will not start

Thanks for all the helpful replies. My father suspected the neutral safety switch might be causing a problem, I will follow your advice Fabbr and report back as soon as I can.
67Dart273, we haven't had the ignition switch installed, the car was hotwired when I bought it and we just replaced the old switch it had. I got a working ignition switch and the keys to match, I will install it and follow through on your advice.

We haven't made any changed to the engine, the previous owner had a shop install a 318, and so far all I have done to the car was fix the rusted out pans and put in a new rear end. We got the engine to almost start last night, but I am thinking its a fuel delivery issue now. I am going to follow all of your replies to make sure everything is in shape and I will post back as soon as I can.

Thanks for all the help!
