I would check the spark and fuel first but do not perform this test unless you are a qualified mechanic that knows how to perform these tests safely.

- I would pull the caps off both distributors and have some one turn over the engine just enough to see if both rotors are rotating (this confirms that your distributor belt has not broken).

- Next I would pull one spark plug cable and install a SPARE spark plug on the cable and ground it. Do not pull any of your spark plugs from the engine to perform this test. Remember you have a second spark plug in each cylinder and if the engine fires you do not want a flame coming out of the spark plug hole. Use a spare plug for this test. Crank the engine over a few turns to determine if the spark plug is getting any electrical spark.

- Reconnect the spark plug wire and turn the engine over a few times. Now pull one or two spark plugs from different cylinders and inspect the plug for any fresh fuel on the plug.

- If you have spark and fuel then I would try starting the engine without the air filter to determine if you have a plugged filter. If it starts then immediately replace the air filter.

Good luck
