Impreza sti 2009 stubborn start in hot weather
 

Hi guys I have an Impreza hatch sti 2009 when it’s sat out in the sun all day where I work it will crank for a few seconds then splutter into life. Once started it runs perfectly and when I turn it off after the first initial start it will fire back up no problem and in the mornings when cold it fires perfectly aswell anyone else had this issue or have any idea of what it could be? I haven’t got a clue thanks

Might be worth checking the CTS, If you hook a laptop up they show 90 degrees even when cold if faulty, typically.

Thanks il look into it see if mine faulty
