Pertronix problem, won't refire! Options

[Dion]

While coming back from a swap meet in Princeton,NJ. The teener started bucking and the tach needle flying up and down. The car would clear its throat and then continue. After a few more of these events it died.I had company while I waited for the flat bed. John I. in his Turbo'd 14 was with me.I did try changing relays with no success. Upon reaching home we took down the front belly panel and found a broken fuel pump wire.The bucking must have been the on/off contact with the pump.
After reconnecting she will not fire. I sprayed starter fluid down the intake.No spark just cranks. Any ideas? Burned up fuel pump? Pertronix fried from key in on position when the engine cut?Where to start? The motor is a 76' 2.0 with smog equip removed. Heads rebuilt 2yrs ago by Otto's less than 500 mile on the heads. New pressure sensor. New battery and starter/coil. Car ran fine till the above situation. Any and all ideas appreciated. Cheers Dion
