2015 Santa Fe Sport 2.0t. Engine runs like the day it was purchased new. No codes or drivability issues. On a cold start or after engine sits for a few hours the fuel pressure drops. The engine takes 3-4 seconds to crank. If I cycle the ignition by turning on without foot on brake then cranking normal it does fine. I figure it is the high pressure fuel pump but would like to hear from any of you before spending 500.00. Thanks.
