SOURCE: No spark?
Hi, common thing with the mazda was the coil or the ignition amplifier going faulty, both of which are located within the distributor, the coil ususally gives the symptoms you describe, a weak spark. The coil is the most common failure aswell for your vehicle i would recommend a new one, also make sure distributor is spinning as it could just be a case of a broken timing belt.
Good luck Davelee

i had the same problem. there is a group of wires that go by the distributer and branch off to the distributer and go towards the front. when i would jiggle it the van would die. it ended up being a pinched wire.

You are jumping to conclusions. Slow down.
No spark AND no injector pulse indicates none of the desired outputs were triggered. The ignition module makes spark when it receives a crankshaft position sensor signal, and then transfers control of that spark to the computer after it starts. The module takes its crank sensor signal and generates an RPM count that it forwards to the PCM(main computer) which is used for triggering the injectors and controlling timing. SO, if you had a bad crank sensor OR a bad ignition module, you could lose both spark AND fuel. a coil would not disable injector pulse. modules RARELY fail in a manner that disables RPM reference to the computer causing it to not fire the injectors...At this point, I would TEST the crank sensor as the next step. If its easier, 1 of the wires on the module goes directly there so you can test the crank sensor at the module.

Testimonial: "great info, thanks!"
You can change pick-up coil, you need to remove distributor (mark where rotor is pointing first) Then you need to remove pin in cam gear on end of shaft to remove gear so you can remove shaft from housing. Then you can replace pick-up coil. Install in reverse. Note when removing distributor rotor will move to the right as you lift distributor out, move rotor to right of mark you made when installing distributor back in.
