I clarify that the problem appears to be in the cylinder one because it is the only one that does not fail to silt fail with disconnecting high cables or the connectors of the injectors all the other cylinders if the head is noticeable when doing this

You can check the load pump and filters, everything indicates that it is due to lack of fuel, when you accelerate more fuel pressure or
or on low it is not enough, also the line is half covered, you did not say so the system is electronic because it can be the admission sensor

Check the coil, this trisado may have the cylinder cable 1.
or you can also check the valves taking the engine compression.
