450don, I have checked and checked everything I did, and nothing, "just cranks"over,I've already replaced coil (napa) got one under $40.00 they have an ignitor (new) for $75.00,do you all think that's next?-cz

Go back and start all over. Put the old parts back in and see what happens.
Remember that a gas engine needs three things to run. Air, fuel, and spark. Have you checked for spark at the plugs? Are you getting fuel? Could you have accidentally tripped the fuel cutoff switch and the fuel pump is not running?
Dumb question, have you checked the timing belt?
