But the motor was still running. So I turned it off.
If its the timing belt I do not think it will continue to run before you shut it down with the key.
Get a carburetor cleaner and spray into the carburetor or the throttle body on an EFI. Did it start and shut off? If not disconnect a spark plug wire or two 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 and listen to the injector/s are they pulsing.
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.
