HELP, Emergency

[carkrazy1987]

I need help, i need to get my car running again in less then 24 hrs or i loose the car. all i need is spark, im having a problem gettin that. Timing is on the mark, all components are new in the distributor besides the capacitor, Dist is an HEI. i probed the coil wire and i have 12volts to it with ignition on. but the minute i turn the key to start, the engine cranks over fine, but i dont get any spark, and i get 0 volts on the coil wire. any sugestions will help.

Thanks
