Re: no spark ??
First guess would be the ingnition switch itself. Have you checked to see if you're getting fire at the plugs when it's cranking?

Re: no spark ??
Wires on the solenoid switched?
Something about start power vs. run power between the two small wires. |

 I'd check the "R" and "S" posts on the starter solenoid.

Re: no spark ??
problem solved !!! when i changed out the dizzy to the msd type i ran a heavier gauge power wire but unintenionally hooked it up to the radio terminal on the fusebox
 this wire has to be hooked up to the unfused 12 volt terminal or youll have these stupid problems thanks for your input guys !!!
