If you were closer I'd come by and test the LPFP for you and see if running it would maybe unplug the fuel lines and filter. I wouldn't be surprised if that is the issue. If you can keep it in a heated place for awhile, that should help.

I'm having the exact same issue as k20power. I started the car, drove it 1/2 a block, pulled over to check my parking next to a curb while it was still running and the car just suddenly stopped, like someone pressed the stop button. I tried starting it, but it would just crank and no start. Exactly like k20power's video. Car seemed to be running just fine before it died.

I did have a code P0471 which I cleared (it has shown up before but caused no issues)

Any ideas?

Just did another test.

At the fuel pump I get ~10 volts at the first plug when attempting to start. However when having a friend try to start the car I put my ear to the pump and heard nothing. Seems the relay is ok but the pump may be bad?

What is odd is I hear people talk about long starts, my car only tries to start for like 3 seconds then gives up. Battery seems good, even tried jumping it to be sure. It cranks no problem, just never starts.

Did another test, thought maybe my lift pump was faulty. I unplugged a sensor on the fuel line near the engine (fuel temp sensor maybe?) and cranked it, fuel came shooting out so lift pump seems ok.

I'm at a loss now.. Not sure what the problem is.

Wish k20power came back with whatever his solution was since my symptoms are exactly the same as his video.

Check the crank shaft position sensor

Is there a way to diagnose the sensor?

Searching I don't see this sensor ever failing on the D's; only the gas E90's. I'm at 83,000 miles currently if that helps any..

I was, (i think) the very first person to have this problem. No codes at first. After towing to dealer and a 3 week vacation there where they threw parts at it, including LPFP, they were at a loss. It did it and then it wouldnt. And then it didn't again.

At the time i had a p3cars vent sensor which would show 'pending' codes on each start. When I fired the car back after it was returned on a flatbed; I got a pending code for "3E90 - crankshaft RPM - no signal "

I never had problems after that but if you google that problem (not even bmw specific), the symptom is the engine wont start.

Ya, I had this issue on an early '00 benz I had which was very common on those cars.

Was yours also a "short crank" like the video on the last page? I hear people complain of long cranks and not start, mine is short like just 3 seconds then gives up. It is very consistent in never starting.

[taibanl]

It's been a while but approximately 3 seconds sounds correct- as if the ECU/DDE knew something was wrong so it terminated the start sequence.

Yes, this is how I feel as well.

Was yours a D? I hate to just start throwing parts at it.. I can't find a way to test it.

Thank you for chiming in, I really appreciate it.

Yes,

I would periodically check if it starts. But try and find that sensor and check connections.

Thank you sir

[dr_dirtg]

not sure if you've checked this already ( i am outta time today to read whole thread) but I had a issue priming my fuel after a filter change, and it took around an hour to get it going again.
What I had to do was apply 12volts to the lift pump and crank for a good 5minutes. ( I gave breaks to the starter of about 30seconds after 10 sec of cranking)
I also had a battery charger hooked up to the car.
Anyway, my 2 cents

[B16]

Thank you. Filter has never been changed. Car wont let me crank for more than a few seconds at a time, even hooked up to jumper cables and holding the start button.

Where the heck is the crank pos sensor on the D? lol

Pre-fill your fuel filter next time...

It looks to be at the very rear of the engine, #8.

Looks like 1 bolt? But hard to get to...

[B16]

Thank you!

Dealer is saying it is the HPFP. $3,300 if only the pump is bad. God only knows if it puked metal shavings into the fuel system.

People have changed out the HPFP not because it was faulty but for higher performance. They switched to what i recall is called an R90 HPFP. I recall they buy them used or reconditioned for WAAAY less than this. If i find a link, I will edit it into this post.

i'm not convinced your problem is the HPFP though. Good luck

[335D Alpha Pappa]

It could be the Fuel Pressure Regulator on the rear of the CP3. Those fail more often than the actual pump.

https://www.realoem.com/bmw/enUS/sho...diagId=13_0958

The problem is that you have to remove the CP3 to access the FPR so you might as well replace the whole pump instead of a single part.

Your DDE codes look like you have a bad exhaust pressure sensor or a soot clogged line to it. FYI

Engine will run fine with these faults for some time, and I can't think of any reason they could be related to your seeming fuel issue.

Based on what?
