Hello, I have a 1992 Mazda Mx-3 with 1.6 liter and I put new plugs in the vehicle in December and now when I go out to start it, it cranks over and does not fire or start I took all the plugs out and dried them off and put them back in and still does not start. I was wondering if it could be the coil that not let fire over. Thank You, John

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
