Hello, my name is XXXXX XXXXX I will try help you with this.
The first thing you need to check is the fuel supply and injection system and if this is ok then check the engine cylinder compressions.
You could also try using 'Easy Start' spray into the air intake whilst having the engine cranked over. If it starts then the fault is fuel related. If it doesn't then it is most likely a mechanical fault with the engine. ie compressions.
