Right got the salvage yard found a d5 v70 2002 with rear end right off

Got the fuel pressure sensor and fuel metering valve of a running car

Still no start fuel pressure stil at 400 then. When cranking its goes to about 1600 then straight back down the 400 within a second

Fitted on there a new filter a man one full of fuel before putting it back on

Did the engine bay diesel tank rig test..used a big coffee jar about 1 and half letters of fuel its sucked all the fuel up turnibg it over by the starter motor .... I got to take my hat off to these starter motors I bet it's done 300 mile just of the starter motor lol .... Didn't even try and start no air in .

Can it be only these 3 things

bad injector will have to get them tested as I have done my own leak test on them they seem good to the naked eye no obvious sings on exssevie leak off

Fuel pressure realises valve other end to the fuel pressure sensor on the rail leaking pressure back to tank

Or the pump witch I think my self seen as I am only gettin les than 10 percent of fuel pressure witch is needed to start 20000 kps my high test value of pressure is 2000 Kps

Also an old guy said a cam sensor going bad can tell ecu to stop fuel is this correct ?

The only fault code I get now is Fuel delivery error lol
Cheer the for the replies mate, keeps me from goin insane
