My car was turn on engine was runinig car was in.

Will the engine turn over (does the starter spin the engine) when you turn the key?

If yes, then you need to check if you have spark at the spark plugs and fuel at the Injectors. Once we know what you "do not have", then
we are able to tell you what to check.

If the engine does NOT turn over (starter not spinning engine), then you need to check your Ignition Switch to see if it is supplying power
to the starter.
