I have a 93 mazda mx3. Its got the 1.8 v6 and a manual transmission. One day driving it ran fine and the we parked it for an hour and went to start it and it just turns over. We checked for spark and fuel and air and it is getting all of those. Its just not starting. Anyone have any clue as to what it could be at this point. Thank you

Compression:
If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems
with compression and valves opening and closing at the wrong time/broken or jumped timing
belt/chain.

I thank you for the information. I checked the compression and its around 120-135 and we checked the timing and the belt is good and its almost dead on from factory specs. Yet the car still just turns over and will not attempt to start. I dont know if there is some kind of sensor or relay or something else it could be. It just doesnt want to start. Thank you again

Re-verify spark and fuel pressure-you got all 3 of them should be able to fire up/combust
