2014 MERCEDES E220/C220 WONT START FUEL PRESSURE LOW

[Bemajor7]

Hi is there any Mercedes diesel specialist on here im having a problem getting my Mercedes c220 AMG Line Bluetec Auto 2143cc engine 2014. To Start up after changing a plastic coolant housing which also holds the fuel filter apparently these are common for leaking coolant and i bought an uprated genuine part from Mercedes anyway it wouldnt clear the EGR cooler so i decided to take off the fuel rail as this seemed like the quickest way to get the coolant housing off as it made room that way i bolted everything back together checked everything was plugged in the car started for a few seconds then died like it ran out of diesel and now it will not fire i do get a fault code some times but not all the time P0087 low fuel pressure but ive had the fuel pressure tested with a proper tester at 248bar cranking has anyone ever removed a fuel rail off these engines and had the same issue i appreciate any information anyone can give me that could help me get the car to start thanks

There will be air in the fuel system if the rail has been off. You will need star diagnostics to bleed it or try turning the ignition on and off giving a 20 second pause between off and on as the intank pump will help bleeding the system. once running clear the fault codes and you should be good to go.

There isn't any fault codes and tried doing that lots if times and still no joy
