high pressure fuel pump

What is your question?

have a 2013 Hyundai Genesis 3.8 l sedan. Vehicle doesn't seem to be able to idle above 2500 RPMs even with the pedal pushed to the floor it still will not go above 2500 RPMS. When the engine is turned off and then I restart is attempted it takes a significant amount of time for the engine to turn over and for the engine to begin to fire up. Normally when you hit the push start button the engine will really fire it up and start right away. But now it takes about 10 seconds of turnover before the engine actually fires up. My question is on the high pressure fuel pump under the hood is it normal to see oil in this area "engine oil"this thing comes directly off the fuel line so I would assume only fuel should be present in this area and I'm trying to verify if this is true or not. I have a weird feeling that someone may have poured oil inside of my fuel tank and attempt to sabotage my vehicle or am I just being paranoid? Thanks.

How long has your 2013 Hyundai Genesis had this problem?
