Help... 2009 Subaru legacy non turbo. Having issues firing. Changed starter about a year ago, replaced crank position sensor, replaced fuel pump, replaced coil pack, still taking a few seconds to long to start. Sometimes won't start on first try. Starter does not whine or click, Maybe Injectors next? Any opinions and advice would be greatly appreciated. Thank you! Sent from my SM-G950U using Tapatalk
