Cranks but Will Not Start

Now for those who want all the details let me start from the beginning because I think this could all be important information.

I started a thread because I was having issues with my starter. I successfully removed the starter, cleaned it up real good, tested it, and re-installed it (did not replace it). Since then the starter has worked fine and sounded stronger than ever. You can hear it in the video cranking away. I bought the car from a private dealer who got it from an auction. It wasn't until when I got home I realized that the rear wiper wasn't working. I've had the car for a while but decided to go out and see what was wrong with it. I removed the access panel on the hatch and found that the motor was simply unplugged. I plugged it back in and turned the car on (didn't start it). As soon as it got power it was wiping away but it wouldn't turn off! I turned the car off and this time decided I was going to start the car to see if it would magically fix itself. I went to start the cart and it wouldn't start. It was doing exactly what you see in the video on YouTube, consistently. My focus went from the wiper motor to this of course larger issue. I can tell you now that the wiper motor is no longer always on and actually cannot even be turned on. I'm not sure at what point it stopped working but I can tell you that I never unplugged it. Again, my focus was on the larger issue of the car not starting. I seriously doubt it is related but I figured it is worth mentioning because that is the only thing that happened in between the car working and not working.

I have tested all relays and fuses. Each spark plug I removed, inspected, and tested. Each ignition coil is sending a strong spark but here is an observation. The starter is turning the engine because you can see the serpentine moving while attempting to start. While testing the ignition coils (one at a time) out of the engine with a spare spark plug inserted into the coil I started the engine to see if the coil(s) were sending spark to start the engine. Sometimes the coil would fire and sometimes it would not. I swapped coils to another cylinder and same thing. No coil never consistently failed. At some point, they all fired but never at the same time. I believe you need all four to fire to be able to successfully start the car. After seeing this I replaced the crankshaft position sensor and both camshaft position sensors. There is fuel being delivered to the rail. I pulled the ignition relay and gave the engine a few cranks to "flood" the engine with fuel. This caused the engine to want to turn over more but it would still die out. I've put my ear up to the gas tank while turning on the car and I can hear the pump starting. After all of this, still the same problem. In fact, the video I uploaded to YouTube is after that work being done. There is no check engine light and also there seems to be no activity on the dash besides the back light that illuminates the cluster. I have an OBDII reader and there are no codes being produced.

If this were your car, what would you do next? Even feel free to tell me what you would go back and test or check again.

Thanks in advance!
