Make something like this:

pawn Код:

new Engine[MAX_VEHICLES];

When engine is turned on:

pawn Код:

Engine[vehicleid] = 1;

When engine is turned off:

pawn Код:

Engine[vehicleid] = 0;

When checking if the vehicle has the engine off or on:
(This would usually go in OnPlayerStateChange)

pawn Код:

if(Engine[vehicleid] == 0) //Vehicle Engine is off
{
//Do what ever you want like freeze the player if the engine is off, so the player cannot just drive away
}
else
{
//If the vehicle is on, do something here:
}

You will obvoiusly have to define vehicle id in places it cannot be used (Such as commands).

pawn Код:

new vehicleid = GetPlayerVehicleID(playerid);

I hope you understand.
