It is other way around buddy. Starter turns engine.
If starter isnt cranking at all that means bad starter or starter relay.
If its cranking and not starting that means so many doubts
AIR, FUEL, SPARK
Air filter isnt choked.
O2 sensor working fine
Fuel filter isnt blocked
Fuel pump is still alive and sending fuel at right pressure. (Usually it should read 30 psi at shrader valve in engine bay).
Spark plug is fine, HT leads is ok, Coil pack is healthy for producing good spark.
