Gremlins in my Demon...........??

Its either a starter relay problem or a nuetral switch problem.If you attach a test light to the soleniod wire permanent and have the light grounded solid so you can see it,it will tell you if the power is at least is getting there,if not you back track,to see where the power stops coming through.If you attach a jumper wire to the soleniod,does the starter turn over right away?So now you go to the relay to see if power is coming out of it,if not,does power come from the ignition switch and neutral switch?If you need the diagrams,I can email you them,Mrmopartech
