I believe the Nomad is describing the way an internal combustion engine works though in terms my old high school auto mechanics teacher would have cringed at.
A 4 stroke internal combustion engine needs four functions to run. Intake, Compression, Power and Exhaust
1) as the engine turns over the piston goes down on the first cycle or stroke creating a vacuum & the intake valve opens to draw the air fuel mixture into the combustion chamber.(Intake)
2) the piston moves upward on the second cycle or stroke and compresses the air/fuel mixture. Both valves are closed (compression)
3) As the piston forces the compressed air/fuel mixture to the top on the 3rd cycle the spark plug fires and ignites the mixture pushing the piston down
(power stroke)
4) on the next cycle back up the exhaust valve opens and expels the spent gasses (exhaust) then the cycle begins again as the piston goes back down drawing in the air/fuel mixture eliminate any one of the 4 strokes and the engine won't run.
The usual suspects for an engine not starting are no spark or no fuel. As u have checked out the no fuel logically next step is to see if it has spark
