Pull the air cleaner and see if it has fuel when you work the trottle. Does the fuel pump run then slow down or stop? If not, it might not be picking up fuel. If the fuel looks like it is working, pull a spark plugs, put the wire back on it and lay it on the intake manifold so the outside of the plug grounds out. Have someone crank it over and watch for spark. Might be the coil is bad, or the rotor broke, or the feed to the distributor is not getting power.
