I did hear the video, it's difficult to say what the fault is from a video. The fuel rail pressure sensor is a 4 wire Pressure and Temperature sensor. Here's the operations of the sensor, the PCM is going to be looking for the signals from that sensor, but you're saying the original pressure/temperature sensor is missing 2 pins on the sensor side, not the harness connector?
If you look at the bottom section of the operations diagram below, it stated the pressure and temperature sensor is used to control the speed of the fuel pump, along with injector pulse width, so having the correct rail and sensor on there would be where I would start with this issue, I'm sure that is going to set a code in the PCM, once that is all repaired correctly, then move on with your diag. If it still doesn't start when you know you have a good functioning sensor and fuel rail, then start checking other components. If the engine has been cranked over a lot without starting the cylinders are going to be washed with fuel as well as the spark plugs, so that is going to affect starting as well. Cylinder wash will actually lower compression a bit.
