my 1992 mazda is a great runner it has lasted past 200000 miles.but yesterday it would not start. the day prior it was running fine. I checked the fuel pump its working fine. i smell fuel.. it is getting spark from the distributor....why would it run fine one day and not start the next? the check engine light has been on for a while... ive checked all connectors and everything is hooked up...any clues?

Pull the code/s from the computer and comeback with it. Also do below-

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel problem, check the fuel pressure to rule out the fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light.

Fuel pump and Injector/s checks out-start checking the ignition system-power to coil, coil/s itself,distributor pick-up,control module, Cam and Crankshaft sensors.

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
