no spark 200 1986

I have no spark anywhere. I checked resistance at the primary and secondary wires on the coil and it is within specs. I have 12 volts going into the coil and when I crank the engine I have a constant voltage on both sides instead of a pulsing voltage. This leads me to believe that my impulse sender or pickup coil is not working. I also have no fuel. I jumped the fuel pump relay and the pump works. I've learned that in order to have fuel, I must have spark. IS THIS CORRECT???? I pulled the distributor out of the car to change the pickup coil. My Haines manual says that there should be a snap ring or a pin near the shaft. THERE ISN'T. I did find a pin on the lower gear....Is this how I take the pickup coil out (By pulling the whole shaft) and if it is, does the pin unscrew or tap out? I guess the other possibility would be a faulty control module and if so, how would I test it. If someone could please help me, I would appreciate it and if there are any other possibilities of what could be wrong, I would appreciate any help whatsoever.

Thank you

You need a spark signal (from the primary side) to trigger the fuel pump relay. No spark means no gas. It's a safety feature.

A dumb question -- is the cam turning? That is, did your timing belt break? If the belt's broken, the distributor won't turn, which means no spark.

As I recall, you can replace the sensor with the distributor in the car.

Those ignition modules are very robust. They hardly ever give trouble. It's much more likely that your engine wiring harness is crumbling, and the ignition wires are shorted or grounded, or something similar.
