Look, the common issues for vehicle not being started properly can be the following:
1. The engine must be turned over by the starter motor with enough speed to catch. For this to happen, the battery must have enough charge, the starter motor and the starter circuit should be OK.
2. Fuel mixed with air in the correct proportion must be supplied to the enigne cylinders;
3. Spark - there must be a strong spark at the proper moment to fire the air/fuel mixture.
4. Proper timing - the engine valves should open and close in appropriate time.
5. Compression - normal compression in the cylinders is 120 - 170 psi. The engine won't start if the compression is lower than 70 - 80 psi.
If the engine won't start - there's no magic - one of these things is probably missing. Sometimes the problem could be very hard to find, for example, when it doesn't happen at all the times. Often, though, it could be something very simple, like a dead battery.
