Hello. The gas pressure is in the right range, do not stop checking the filter and measure fuel delivery, 1/2 liter in 30 sec. Approx.
In the sensor appearance, check resistance and operation of the ECT.
It is a normal condition that the vehicle starts with the disconnected tree sensor, since it is a reference to regulate the ignition time, your fault could be there, that would mark it almost immediately in the scanner as "CMP circuit in failure".
Another important point is that you check the pressure regulator, which if you are doing its job as we can account for the pressure of the rail, but we could have it with a leak to the engine for the vacuum duct.
I hope this helps you.
