    with diagnosis connected in the gear I find "pulse width injection" that goes to zero in the moment where I have the tear and also a "quantity of fuel injection (torque control)"
    these two parameters are "0" as soon as the car rips, and the rail pressure drops drastically

    hello joseph, if I can, it seems to me a power problem, pure and simple, by increasing the rpm increases the voltages vpp to the injectors.
    the error affects all the injectors if it was one that went in short, it is very rare but happened, you would have had an injector with the error seuire.

    the control which, according to me you should get and the wiring that does not have some broken wire or slightly paraded that causes the loss of tension that clearly expresses to the mass, or the ic power that feeds the injectors that heating it must be short and send you in protection.

    very often it happens that people who put their hands neglects some particular types of supports that hold cables etc.,
    these, resting on the hot surface come to cause such a mess.

    the DTC and real.....fixed on car is different but with the same injection system and same symptom.....however, the ecu had been tampered with, flow, for the scodifica and then he found this problem.

    In the piping of the diesel that you have changed one of the return fuel is usually transparent and should be full of fuel and therefore must remain transparent. However, if you see bubbles of air or the diesel fuel, which become almost white because they are so many micro bubbles it means that which enters the air in the pipes, otherwise disassemble the injectors and portals from a pompista for them to check.
