need electrical help please

left the house today for a ride and after about 10 miles down the road, the car dies. get stopped down the road and try to restart it but no good. get it home and start playing with it but still nothing. it does spin over and its getting gas but there is no spark. i have changed the ignition module and made sure that all the wires and connections are good but still no luck. any suggestions will be great.

o and its a 78, 350 auto.

the rotor looked fine but ran out of daylight before i checked the voltage to the coil, if i have voltage to the coil then i might just change the cap and rotor anyway im not sure how old they are. i know it has to be something simple.

Well I hope it is but one problem that is easily missed is a break in the wires that go from the module to the pickup. They are flexed back and forth every time the vacuum advance changes and can break inside their insulation.

Check the fuse box for any blown fuses, I made that mistake once and wasted 3 days on nothing until I checked the fuse box. Hope this helps!

broken hot wire going into the coil, couldnt see it with just the top taken off, had to take the coil out to find it. wouldnt have figured it out until i changed the cap and rotor. now have to retime it. it is off real bad.
