Did some work on the x5 today; then started digging into the fuel pump issue.


Found no juice coming to the fuel pump.


The 25A Fuse #47 in the glove box looks OK.


I can feel the FP relay clicking when turning the key to pos 2.


Didn't have time to bench test the relay, so I ordered one from AutoZone ($19.00, want a spare anyway).


It should arrive by 6PM tonight.


Hoping that's the problem while I wait for the new FP and filter to arrive.

Cool No such luck

I replaced the FP Relay; still,no power getting to the FP.


There may be an ignition switch of some type, not allowing the high voltage to go to the FP Relay.

What scanner are you using? Mine will show me each key terminal value etc.

Hi,


I have 2, one is a Bosch 1,000 and I have the free Torque app bluetoothed in.


Both read the original code; still learning the torque app.



I checked fuse (area) 51, it looks fine also.


Could the cam pos sensors shut down the juice to the relay?

The initial pulse to the fuel pump I think runs regardless of CPS. Without cps you won't get spark from my understanding.

To eliminate fuel control from the equation you can jump the relay once you confirm the live side of the relay has power I think that might be F51 unless that's just the control.

The control for the relay needs both power and ground. A lot of systems on E53 have always power and controlled by ground. See which fuel relay is and determine if part is missing.

Safety circuitry on most cars will kill fuel pump if SRS activated or flip over is detected. Was this car in an accident?

The Volvo I worked on I thought the fuel pump failed so I jumped the relay with my DMM on amp mode so I could also measure the fuel pump current (about 6 amps)

No accidents or floods according to seller.


Has a clean tit


Can't even copy and paste tonight. P1343 has 4 or 5 possible.


Faulty plug, coil, vacuum leak, CPS, ignition coil or harness.

Can you read your intake/exhaust vanos with your scanner? It will let you know your cps working

I'll check on vamos in the morning.


I'm pretty sure Torque has a widget for that.


I just watched a vid on testing the cps

More checking today; should first thank everyone for all the help.


Power exists at the relay terminals and at fuse 47.


Still no power to the pump.


Gonna check for ground continuity at the relay terminal and pump.


Currently flabbergasted on who designed the auto correct in my phone (a South Pacific cannabal?) and why an "easy fix" on this car isn't in the cards I've been dealt....


Might have to trailer this car to a pro-shop.
