Misfire and flooded cylinder

Hey guys, I'm having a pretty weird issue with my 2010 JCW. I'm researching it now, but if someone knows about this please inform me.

I just got code P0302- (cyl 2 misfire)
P013E- (lean o2 sensor 2)
P2187-( lean o2 at idle)

When I pulled the plugs out, Cyl 2 was fairly full of fuel. I waited for it to evaporate out.

When my girlfriend hopped in to turn the ignition over with the plugs out, she pressed the start button and the key icon popped up( I had the key out of car). At this point injector 2 started going pulsing fuel out and flooded the cylinder. I could hear a groaning sort of sound from the HPFP. Keep in mind the key was out, so it was not even able to go into assecory mode.

Cyl 4 had some fuel vapors in it as well, but no standing fuel or pulsing injector.

I'm thinking maybe something to do with the HPFP or a faulty injector, any clues?

Thanks!

I took out the injectors, they all look good visually. I tested them with an ohm meter and they all were close to eachother.
Does anyone know any other tricks for testing injectors?

With the ignition on but the engine not running the injector will not fire. If its spraying fuel the injector is stuck open. Replace it. I'd change all 4 along with the fuel filter myself.

Yep, I confirmed it. It is stuck open. I have a new set of injectors arriving today. A new fuel filter is a good idea as well.

Good that you caught this early, a stuck injector could have destroyed your engine!
