For a mechanically good internal combustion engine needs the following things to run: fuel, air, ignition - in the right time. Lack of these could cause the no start condition.
I'd check spark first, than fuel pressure and go from there.
Check for fuel, bridge B+ and FP in the black diagnostic socket box in the engine compartment that makes fuel pump run, check for spark at plugs and then check for mechanical integrity (compression engine components in synchronization. ).
