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.

Hi, I'm one of the auto experts on RepairPal's Car Genius team! I completely understand the concern! To address your specific question first, on the 2013 Hyundai Genesis 3.8L the high pressure fuel pump is actually mechanically driven by the camshaft and the pump is lubricated by the engine oil system. So what you're seeing there is likely not cause for alarm and is probably not sabotage. It is more likely that the seal (or another seal nearby) has failed and is the source of your oil. That said, the symptoms you're describing including the RPM cap at 2500 and the extended crank time before starting are definitely worth investigating. These symptoms together could point to a failing low pressure fuel pump or high pressure fuel pump not building adequate pressure, a faulty throttle body, or the vehicle being stuck in a limp mode due to a stored fault code. I’d strongly recommend having a qualified shop pull any stored codes and perform a fuel pressure test as a starting point, as these two steps alone will likely point directly to the root cause. The extended crank time combined with the RPM limitation suggests a fuel delivery or engine management issue that really needs proper diagnostic equipment to pinpoint accurately.
