On a 1994 Mazda MX-6 : Both the 2.0 liter four cylinder engine and the 2.5 liter V6 engine have a timing BELT
Here is documented replacement of the Timing belt on MX-5 1.6L It has really good images, so you can see the lay out http://www.racecaddy.com/mx5/tech/timing-belt-mx5.html Good luck
It's inside the timing belt cover. It's a pretty difficult and may take about 4 or 5 hours to change. While you have the cover off change the timing belt!
To change the water pump on a 1993 Mazda MX-3 with a 4-cylinder engine, first, disconnect the negative battery terminal and drain the coolant. Remove the drive belts, then take off the timing cover and loosen the timing belt tensioner to remove the timing belt. With the timing belt out of the way, unbolt the old water pump, clean the mating surfaces, and install the new pump with a new gasket. Reassemble in reverse order, ensuring proper alignment of the timing belt and tensioner.

The first thing I would check is to make sure the ignition timing is correct... And the cam timing belt or chain if it's separately timed from the ignition. If it's not either of those, I would check all of the engine control relays and fuses and make sure all of them are functional.
