yes you need the starter support.
the hard start could be filters or you could have crap in the tank blocking the fuel pick up. if you don't use Bio guard fuel conditioner you may have a tank full of black crud.
it can and will imitate fuel system problems like a weak pump or cavitation at the injection pump. start there. its the cheapest place to begin
