Low fuel pressure will not wont start d5 2002

[cheshired5]

There's plenty of options so you tackle it how you feel is best.

Personally, I would start with the free "make a diesel rig in the engine bay test" and see if it starts.
I'm not a fan of parts replacement without testing but sometimes needs must.

Got a dim out a 2003 v70 petrol works absolutely mint

Trying to get hold of a fuel pressure sensor any one know were to get one apart from Volvo

[cheshired5]

Try Huddersfield Volvo Breakers.

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

[Jack5cylinder]

would a proper volvo reader tell me where the fault lies

Also I took the main feed to the fuel rail Off just that end ,shoud I be able to near enuff stop the fuel coming out whilst my pal is cranking her over

The fuel pressure regulator was off a NEWER engine so I can't rule that one out also the connector is in different postion so going to have to get a brand new one

Or I could just buy a brand new pump from eurocar parts with a new sensor already init for just under 200 pound I know it's a lot but sensors are like 60 to 80

just keep in this thread Jack and you'll be fine

The sensor isn't on the pump, it's on the opposite end of the rail.
You could buy a HP pump from a breakers for about £50.
They hardly ever go wrong so aren't in huge demand.

Sorry I ment regulator and yeh I think that's next just goin to pul the pipe off the pressure release valve to see if I'm losseing pressure there returning it back to tank .

WhAt do u think about ecu and wires should I test them with volt meter

Cheers

There are many things that are possible but for now, I would stick to the things that are likely.
Leave the ECU alone.

Yep don't wana break any thing els lol

It's just I was reading another post about a guy who getting simler fluctuation with his fuel rail pressure on live data loads of pages down he uncliped the ecu and reseated it and it's cracked up but yeh I'm with you likey causes of low pressure.. Fist to come to mind is pump no matter the the car

Good cars thought I have had two s60 d5 one a SE the other s.fully leather heated seats both had done more than 200k and didn't have to put a spanner to them drove like a new car
Terrible full lock tho lol

Hope I can get this one alive agine hehe
