PITSTOP: NO START OR HARD TO START CONCERNS - Some 2014~2015MY Forte Koup / 5 DR equipped with a 1.6L GDI Turbo and produced before July 14, 2014, may experience a hard to start concern or idle rpm fluctuations while stationary. If you encounter any of these concerns, check for white residue build up in the High Pressure Fuel Pump Inlet (see image below) which may cause a restriction and loss of fuel volume to the injectors.
