If the gasoline engine only cranks but never fires up, one of the most cost effective ways to test whether the fuel system is at fault is to spray "Starting Fluid" into the intake manifold, down-stream of the MAF. If you have not use starting-fluid before, be aware that starting fluid is extremely flammable. No one should be anywhere near the opening of where you sprayed. Although, I myself have never have anything bad happened to me personally, potentially it can. It may be prudent to wear a protective glove too.
If the fault is only due to the fuel system, the engine will start right up and runs as long as you continue to spray into the intake.
Combustion will take place if a good spark occurs at the right time, and a sufficiently well mixed air/fuel charge is present at the right ratio.
