Citroen relay van

Still having problem with my vehicle

It has hard starting problems but when I do manage to start it runs fine.

the problem I can see is it has come up with code p0090 which relates to the pressure relief valve . I have 3 of theses valves and have tested them all on a 12 v battery and seem to be operating fine.

the problem I have noticed is when I take a volt reading and the socket it is only about 6v should this be higher?


I have just plugged a spare one into the socket and turned on ignition to see what is happening and it doesn't move much. ie that the valve doesn't close. if this is the case with it fitted into the high pressure pump it cant be producing enough fuel pressure to start hence hard starting.

can any body share and problems they have had and possible solutions .
