diesel 75E17 engine misfiring?

hi pete ..i think i have info overload lolat least unlike many you give a thorough description of your fault ..so i will try my best to help ..1 or 2 bits do confuse me ..but i will try my best to assist..The common rail is just a tube feeding the injectors so why you aren't getting fuel to 2 of the injectors is a puzzle..So starting with difficult starting ..that sounds like a fuel pressure issue ..you haven't mentioned any warning lights so i will dismiss a fuel blockage .Issues can be the prop valve on the main fuel pump which has the elec plug on it ..Another issue can be fuel leak off back to the fuel tank...To check that remove the leak off pipe at the rear of the cylinder head,and fit a pipe to the head in to a jug..Remove no 1 injector pipe and fit a blank on to its position on the common rail ,vehicle will now be runnning on 3 cylinders ,run for 1 min and check fuel in jug shouls be less than 30ml if not continue till you get less than 30 ml ..the injector that is blanked when you get less than 30ml is the faulty one ..replace injector and redo test as now you have sorted any excess leak off the pressure will find the next weak point if there is one ..Also check pushrods ,just did a misfire running on 3 cylinders and the bridge pieces where off the valves 1 pushrod was bent
