Help: Engine crank but fails to start

2004 Honda Civic vti s manual
1mo ago nasira alternator ko, tinangal ko battery terminals (+/-)
This week kinabit bagong alternator, binalik battery terminals (Battery is charged)
Pag start, mag crank pero di tumutuloy yung engine.
2days na sa casa yung kotse, di nila makita problema.
Na check na electricals
- Battery ok, ECU ok, Sensors ok, Sparkplugs (new) ok, Injector ok, Fuel pump ok
Na check na engine
- Timing belt ok, Oil pressure ok, Pistons ok
Throttle body cleaned, fuel drained replaced with new fuel, lines were cleaned including the injector.
Original and duplicate key from casa used.
Still no start. Ano po kaya problema?
