Are you using gamemode to make a engine system?
Try this..

PHP код:

#include <a_samp>
#include <zcmd>




public OnFilterScriptInit() // Use it as filterscript instead..
{
      ManualVehicleEngineAndLights();
      return 1;
}

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
    new vehicleid = GetPlayerVehicleID(playerid);
    if (vehicleid) {
        if ((newkeys & KEY_SUBMISSION) && GetPlayerVehicleSeat(playerid) == 0) 
        {
            new engine, lights, alarm, doors, bonnet, boot, objective;
            GetVehicleParamsEx(vehicleid, engine, lights, alarm, doors, bonnet, boot, objective);
            if (engine == 0) engine = 1;
            else engine = 0;
            SetVehicleParamsEx(vehicleid, engine, lights, alarm, doors, bonnet, boot, objective);
            return 1;
        }
    }
    return 1;
}

CMD:engine(playerid,params[])
{
    new engine, lights, alarm, doors, bonnet, boot, objective;
    new vehicleid = GetPlayerVehicleID(playerid);
    if(IsPlayerInAnyVehicle(playerid))
    {
        GetVehicleParamsEx(vehicleid, engine, lights, alarm, doors, bonnet, boot, objective);
        SetVehicleParamsEx(vehicleid, 1, lights, alarm, doors, bonnet, boot, objective);
        SendClientMessage(playerid, 0xFFFFFFFF, "Your vehicle's engine is now turned [ON].");
    }
    else
    {
        //Send a message telling he is not in a vehicle to manipulate an engine
    }
    return 1;
}
