Unless you suspect you have a faulty ECU (highly unlikely) there is probably only a few reasons it will crank but not start.

No fuel.
No power.

So get back to basics, make sure you can hear the fuel pump running, make sure you have fuel, make sure you have good volts, make sure all your fuses are ok. It is not clear to me if you have ruled this all out.

If all of these are good, the yes you start to get into the more complex diagnostics. So then start with looking for damaged wiring, fuel restrictions etc. And lots of Google research helps.
