First time mods on my 318 and it won't start...

It sounds like when the ballast resistor is burned out.

Sure does, but he didn't say he messed with anything in the ignition.

OP, if you crank it and it starts but immediately quits when the key is released, it could be the ballast resistor. To check it, pull the plugs off of it and use a small piece of wire as a jumper between the two wires, and see if it starts and stays running.
