How do you know if im getting spark?

The easiest way to find out is to remove the wire from the spark plug and hold it about 1/4 inch from ground (the engine block is good) while someone cranks the engine in short bursts. If you are getting spark you should see a blue spark jump fromt the wire to the engine block. You might want to check all spark plug wires while you're at it. If you want to check the spark plug while you're at it, remove the spark plug and attach it to the end of the wire before checking for spark. If you get spark through wire but not through the spark plug, the spark plug is bad.
