P0340, P0365 and P0315 crank, no start

Hi, I have the vehicle listed above I purchased back in February, not knowing it was a first year first generation. I won't make that mistake again, it has been a problem child to say the least and I will do my best to keep this shortish.

About a month ago out of nowhere it left me stranded in a Walmart parking lot having to be towed home. Constant misfires, oil in my spark plug tubes, gas in my oil, as well as a mix of them both in my air intake duct. So doing everything myself and feeling like this vehicle needed some TLC I replaced spark plugs, coil packs, all camshaft sensors and solenoids (VVT), all O2 sensors, valve cover gaskets, manifold gaskets, spark plug tube seals, and thoroughly cleaned out bank 1 and 2, air intake, and throttle body.I'm sure I'm forgetting something but moving on. Got it all back together and no crank. After a new ignition switch it turned out to be a faulty solenoid on the starter I installed only a month and a half ago. After installing replacement starter finally it cranks, Yay. But no start :( OBDII reads codes listed in title and reads 0 RPM's during cranking. I replaced the crankshaft position sensor a few weeks after getting the vehicle and had the relearn done on it but it did not leave in a no start situation at that time. I have been through the wiring for the camshaft sensors but am at a loss.

Any advice would be greatly appreciated. To start my pocketbook kept it out of the shop but at this point it has come down to my pride.

Thanks,
Jenny
