Hi, My name is***** will be glad to help. We can follow up as needed on here. Professionals are not employees of the site but users of the site and help on here as time allows depending on their daily schedule.Start by checking for any leaks or restrictions between your fuel tank and fuel pump. If you have confirm this and have also confirmed good fuel supply to the high-pressure pump as you have stated, you will want to check your fault code history logged within the ECM. If your machine does not have the optional display screen that allows you to retrieve fault codes, you will need Caterpillar electronic technician diagnostic software connected to this machine or you will otherwise be guessing on everything. Caterpillar electronic technician is going to allow you to visually see all fault codes logged, view all parameters in live time, have the ability to run tests and calibrations, as well as potential software updates if necessary but this would be through the dealer version that is unavailable to the public when it comes to the updates. The fault codes are going to give you a better starting point to determine whether or not low fuel pressure in the rail has been detected, possible loss of engine speed sensor signal, monitoring commanded fuel pressure versus actual fuel pressure, etc.. This common rail fuel system is not like older style fuel systems since it is ECM governed and controlled. Reply back with the results of these checks as well as any fault codes you have logged if you are able to access them if any further help is needed. I hope you find this information helpful and it's a pleasure to help anyway I can.
