Question about 1993 Mazda MX-6
According to the wiring diagram, there is no inertia switch on a Mazda MX-6. The fuel pump circuit only has a pump relay which is powered by a fuse and grounded by the computer.
And if the car did have an inertia switch it would not affect the ignition system.
If you have no spark and no fuel pressure I would check the circuits for the pump, coil, and computer at those fuse locations and beyond. Could have shaken something loose at the key switch or in the wiring.

Before you replace the fuel pump, I would check the cheaiper parts first. Such as fuel filter and injectors.

What you can do is disconnect the fuel filter and have an assistant watch under the vehicle while you turn the ignition switch (but with out actually turning the engine on. If the Fuel pump is an electrical fuel pump it will spit out fuel for about 3 to 5 seconds.
If nothing happens then a more extensive method to checking the fuel pump
Ok if you could find the fuel pump relay.
It will have either 4 pins or 5pins
This is a trick to activate the fuel pump with out the engine actually running and for longer that 3-5 seconds.
the 4 pins are numbers 85 86 30 and 87 (87a)
If you can remove the relay and memorize where the pins go. Then acquire a bobby pin or paper clip and cross the terminals 30 and 87 (87a) and if the fuel pump activates then it functions but remember to have the key in the ignition with it to the run postion but the engine off. If this works then the relay could be bad, Test Terminals 30 and 85 for resistance.

Check the Fuel injection system (injectors) and the intake manifold. It might also be wise to check the alternator as well as the starter coil and also the electronic distributor

Yes there is a history of problems with this system, one is the limit switches at eacg end of the track and the other is the motors, there is no real fix other than replacing it.

Sounds like it could possibly be a vaccume problem, the computer sees that the vaccume has a low pressure and thus fludding the engine, or visa versa, it's seeing too high of a pressure and cutting the fuel comsumption to a minumum enough to make the engine sputter and die.. Does this happen when the cars in Netural or Reverse or Park? Just Drive?
