Fuel Pump Died Will 540 pump fit?

Died last nite no warning. Lift rear seat, put ear to pump area, wife toggled key to pos 2 and back, no noise at all from pump.

Fuse ok, AUS cars dont have the big relay in trunk. NO codes on Peake, I think pump? Car is 122k km or 80k miles, 1/2000.

New one 2 weeks from USA, so I picked up a used 540 pump this morn, will it work till new one gets here?

Pump part looks different, but yellow plug looks same.

Thoughts?

You do have a relay. It's the green one in the boot shown below. It sounds like you have checked the main fuse F54. Did you check F31?

You can check which failed (relay or pump,) by putting a 14 gauge or heavier jumper wire across pins 6 and 2 in the relay connector. If the pump runs, it's the relay. If not, it's the pump.

And no, I don't think a 540 pump will work. The M5 has a higher pressure 5 bar pump.

Only reason is:Another member down here told me he used a 523 pump to get going for a week or so till correct part arrived. and car drove ok.. its only one I could find from breakers in Brisbane

obviously pressure and flow wont be to spec, but if i am mobile at least I save tow fee home?

Car will run somehow with it,but very quickly reach the 25% max addition.

Is ok to limp home,but not for extended driving.

Rather open the old fueöl pump(open the rolled edge) and solder in a set of generic brushes(as yours will have worn out brushes) that you shaped to profile or get another regular used E39 pump to use its brushes if you have to drive for a few weeks until replacement arrives.

As previously mentioned the E39 fuel pump ( BMW Part # 16146752369 ) runs at 5 bar and is unique to the M5. Good luck.

Aeromotive 340 lph pump should work if that is more available to the OP. It is almost a direct fit.

Regards,

Did you check the wiring colours to the relay you pulled matched the wiring diagram above? I remember seeing past posts about some confusion about which relay was which.

If the fuel pump brushes and commutator are bad enough the pump doesn't run, I wouldn't have expected the paper clip to pass enough current to get hot.
