The problem is either spark or fuel. The first thing to check is the spark side. (And, how old are the spark plugs?) Then look to the coil/igniter inside the distributor. You need some method to determine if you have spark. You could remove a wire and place it next some body metal and turn it over or use a timing light that will do the same thing. (You are not checking the timing, just looking to see if the light will trigger).
