FC 4726 is also associated with the fuel rail bleeding off too fast.

- Do an injector leakage test on it exactly like this video shows... find out why its bleeding down...

Is the engine del-eted? / de-mandated?... if so then copy program from ECM and e-mail it to me to have it reviewed. - Could be a bad delete settings or 2 that is torturing the fueling system or causing too high pressures.
