Ok, Engine starts to fire then quits when key is released.

check the wires going to the resister for a short, you also may have gotten a bad new resister, checking for voltage to the resister and coil with the key switch in different positions will help determine where the problem lies, if there is voltage to one side of the resister (the key switch side) and not to the other side (the coil side) it is a bad resister if there is no voltage to either side with the key in the run position it is a short or bad ignition switch
