    confused Is my Fuel Pump Goosed?

    Need some advice on what to do now.

    I have not been able to get mycar started after changing fuel filter.

    Had the car checked for error codes and one code kept coming back time after time.

    Code - P0090-5B Rail Pressure Control Solenoid Valve Circuit Range/Performance (Positive Deviation)

    Checked if any fuel was getting to the fuel rail, loosened nut off the back of the rail and pipe from fuel pump was bone dry.
    This could explain the fault code as no fuel is getting to the fuel rail.

    Could it be -
    The solenoid on the High Pressure Fuel Pump?
    Blockage between filter housing and HP Fuel Pump?
    The HP fuel pump?

    Seems strange as car was running fine until I changed the fuel filter.

    Could do with some ideas / tips on what to do / try next?

    Dont want to start buying fuel pumps etc if there is a simple solution.

    Thanks in advance

    Is the fuel filter blocked? Would do the same if it is clogged up. Could it be the pump in the tank has given up, and a pocket of air has made it into the engine? I would seriously have the fuel filter investigated first and foremost.

    Fuel Filter seems to be ok - housing filled up after turning key 3 times after replacing it.

    Decided to remove the filter to check it was fitted correctly etc after it didnt start the first time.
    When I removed the hoses from the filter housing, the diesel within the housing came out at force, dont know if this is a good or bad thing as it didnt do that when I first took the hoses off to replace the filter. Diesel looked like it had a lot of air in it, foamy like, if that helps.

    Low pressure pump to filter housing is ok

    Sounds like the outlet from the filter housing has been blocked, as there isn't usually a lot of pressure in the filter housing.

    Is the filter the correct one, and has it been fitted correctly?

    If all you did is change the filter, and now the engine won't start, then the filter is almost certainly the culprit, unless by great coincidence something else went wrong at exactly the same time.

    Thanks for that, put my mind at rest a little bit.

    All that has been changed since car was running ok has been the filter.

    Genuine VX filter and seal from dealer and it was fitted correctly eg arrows lined up and short twist, housing tightened to 30Nm and no leaks from housing.

    I thought it strange that when I took the hoses off the filter housing the second time, that the fuel was spraying out all over the shop.

    Sound like the filter housing is pressurising / filling when ignition is turned, but the fuel is not going anywhere, apart from all over me when I took the hoses back off.

    Any ideas where the blockage could be?? (within the filter housing or the pipe to fuel pump)

    Or do I need a new filter housing?

    Car been off the road for a week now and doing my head in
