Mein Auto: 540i
2000 540i won't start

Hi everyone. This is my first attempt at posting on Bimmerfest so be gentle with me. The problem first started with the 540 starving out when I gave it the gas. Then it quit running a few times and it started back up after a few minutes. It finally quit running. I replaced the air cleaner and then the fuel pump. I used a TREperformance TRE-340. Only had to solder the wiring. The 540 started right up and I drove it to the gas station. It died once on the way. I drove it home and it quit again (read i hr wait for AAA). I then replaced the ignition switch and the car still will not start. I can hear the pump when it runs. By the way, what is the secret to getting the metal retainer ring to seat properly? I finally bought a new seal. It helped. So now I am out of ideas. Oh, by the way, I cleaned the battery terminals. I love my 540. It looks good in the driveway. The tow truck driver says he makes his living towing BMWs. Anybody have any ideas?

Check for any fault codes? Have you changed the fuel filter and regulator? Have you had fuel pressure gauge on it?

What mileage is it?

There were no fault codes. Fuel filter and regulator seems like the next logical step. The 540 has about 150,000 on her. So she is probably due for some tender loving care and some new parts. Can you tell me where to check the fuel pressure? I don't own a gauge but maybe I will pick one up. What would be the correct reading?
Thanks for your help

are there any lights on the dash (battery light?) check engine light?

if batt light is on I would question your alternator.

If check engine light is on get it scanned.

take the acoustic engine cover off. and on the fuel rail there is a valve you can hook up to with a fuel pressure kit.

A lot of part shops will loan you a gauge. From memory it should be around 50 psi.

Yes it is a 3.5 bar FPR or about 50psi.

Thanks. The test gauge was kind of spendy. I have a bmw mechanic friend who is coming over this weekend to help diagnose the problem. I will keep everyone posted. I hope that TRE-340 pump is the real deal. Has anyone actually installed one and had it work? The tech rep from TREperformance said it work fine.

If it functions just as the Walbro does you won't have issues!

I hope so. I will let you know. Could I remove the retainer ring turn on the switch and see if it is working?

Have you already replaced the fuel filter? If original, it's way past due.

bricas45, the early V8s do not have a pressure measuring port. It appears that the later ones have a port on the fuel rail. It appears to need a special tool. Can't tell whether it's a Schrader valve or not.

Yes the later models do I assume it came with the Vanos updates. Here is a photo.

TRE 340 hose problem

They cause off all my grief was a bad flex hose witch developed a bubble and then burst. I replaced the hose and it is running fine. TREperformance needs to supply a better flex hose. The positive result is a purchased the pump for around 70 bucks witch includes shipping and handling. I also can pull a 540i fuel pump and re install in record time. Thanks all of you for your suggestions and support.

That's great. Was this a hose that came with the pump?

Some info on the actual pump (e.g. model number, fitting steps) might be useful for anyone who stumbles across this in the future and me if I ever need to replace my pump....

The pump is from Treperformance. The model number is TRE-340. And yes, the hose came with the pump. It was a lot thinner plastic than the original one. I went to Autozone and purchased a rubber gas line (a little over a foot.) for $ 1.29 and also picked up 2 larger clamps. Also, I had to solder 2 electrical wires to the clips.

Make sure the gas line is rubber free and ethanol ok...trust me had one disintegrate on me on the fuel filter in like a month!

Fuel pump 540i

The saga continues. I drove the car about 3 miles and it quit. I am on my way to the BMW dealer to get a fuel filter. Hope this is the problem. When I gave it the gas, it bogged down and then wouldn't start. I am running out of my AAA tows. Good info on the hose. I will make sure I have the right hose.
A clogged fuel filter could cause the hose to rupture.

Stay tuned

So, did you ever check your fuel pressure? A 2000 does have a schrader valve, and 50 PSI is what you should see at the test port.

fuel filter

Not yet. I believe the filter is original and since there is 150,000 miles on the 540, I am going to replace it. It should take less than an hour to replace it with a new genuine BMW filter.

200 540i fuel filter replacement

I replaced the old fuel filter with new BMW filter from dealer. 138 bucks. The old filter was so clogged that I could barely blow through it. The new filter easily let air pass through it.
So now I have replaced the fuel pump. Installed a new ignition switch, replaced my K&N air filter and replaced the fuel filter. May be I should have started with the filter! The car starts and runs. Took it on a test ride and it periodically ran rough then smoothed out. The car starts and runs great including pulling some high RPMs in the driveway. Maybe I need to take it our on the freeway and open it up. I was still getting a loss of power when I accelerated. Not as bad as before when the car would bog down and a quit running. The good news is no AAA this time. I suspect something still is not quite right. The next step is to run a fuel pressure test. One more thing, the ruptured hose was caused by the fuel filter. The second time the pump stopped working was caused by the hose being blown away from the fuel pump. Luckily the clamp stayed on the hose. Still thinking about replacing the TRE-340 with a BMW fuel pump. A word of advice to everyone. Replace your fuel according to PM guidelines. I probably would have saved a lot of money, time and grief.

Sound slike your making progress! I'd give it a bit of a run, ECU might need to adjust the fueling a little after getting used to being staved of fuel.

Fuel pressure test won't hurt either. Especially as it cheap if you borrow the gauge.

Well, I gave it a run. It does fine as long as I don't hit passing gear. After I hit passing gear it bogged down a few times. At least it didn't stop running and with the resulting call to AAA! I am going to rent a gauge from Autozone and see where I'm at with fuel pressure readings. I feel like I am getting closer. It is really quicker.
