BMW E90 3-Series Fuel Pump Replacement

Replacing the fuel pump on a BMW E90 can be done without removing the fuel tank. There is an access panel under the rear seat cushion that allows servicing. A faulty fuel pump can cause poor engine performance and hard starting problems. When they fail completely, you may be left with an engine that doesn't start. If you suspect your fuel pump has failed, you can confirm the fuel pump has received the correct voltage when commanded ON by the fuel pump relay using a digital volt ohm meter (DVOM). If the correct voltage is present, but pump does not activate, it is likely faulty. Use the DVOM in conjunction with a wiring diagram to determine the correct terminals for testing. You can access terminals under rear seat cushion, below access panel. See our tech article on fuel pump testing.
It is best to replace your fuel pump with the fuel tank drained. This reduces the amount of possible spilled fuel and fuel vapors. When replacing, work in a well ventilated area, working outdoors is a good choice. Do not use incandescent work lights or power tools, fuel and fuel vapors are highly combustible.
Drain your fuel tank. Run vehicle for about 20 seconds. This equalizes the amount of fuel in siphon unit.
Disconnect negative battery cable. See our tech article on battery replacing and reconnecting notes.
Remove fuel cap, then slide an anti-static siphon hose down fuel filler neck. Once hose has bottomed out, pump fuel out of fuel tank into a suitable storage container. If you are unsure of amount of fuel in your tank, you can monitor fuel level via the fuel level sender units. As fuel level drops, fuel level sender resistance drops. You can measure this across the terminals at both sender units with a digital volt / ohm meter (DVOM). You will need a wiring diagram from a repair manual.
The fuel pump is located in the right side of the fuel tank.
Working in rear of vehicle interior; grab corner of rear seat cushion and pull up to detach locking tabs. See our tech article on Seats removing.

This is easily the best step by step car install video I have seen in years. Quality explanations for each step and great footage including arrows to ensure viewer understanding. Thank you :)

Glad you liked it!

My mechanic wants to charge $1000 for this job to be done, is that accurate?

[@pelicanparts]

I am not sure what the repair will cost in your area. Call a few shops and ask for a quote. It is also a good idea to have them confirm what the issue is.

[@CoDModzFTW]

@@pelicanparts it’s in Georgia, USA.

That’s not a mechanic, that’s a predator

[@schonkat1982]

With labor and parts could be as high as 800$ pre tax. Pennsylvania, January 2022. That's what I got quoted by BMW and that's what it was

[@blndrckr]

​@iamher6422 hmmmm, can you cite that?? It's a bit of a pain in the ass job and a quality fuel pump ain't cheap for the part. Also, you need to understand, repair facilities mark up parts. It's an expected industry standard to cover the costs of overhead. Facilities with high overhead hate to have customer show up with their own part....if so, they'll just likely increase your labor cost
