if your not sure about spark, that would be something very valuable to find out.

stick a screwdrive between the gap and hold the screwdriver near some bare metal on the frame, keep it away from the valve cover or anything oily tho.

yeah, your looking for a spark, and you have to be trying to crank it, pull the fuel pump fuse before hand also so you dont flood it out.
