Default Fuel Supply error - engine shut down 535i Walbro 450 F90000274 - 05-23-2019, 12:03 PM

After installing Walbro 450 F90000274 I have had "Fuel Supply" error pop up on idrive and then a few seconds later the car shuts down completely after a drivetrain malfunction error. It does crank/no start, and will not restart until I wait about 5 minutes and it restarts and drives fine.

I'm getting the code from JB4 - cylinder injection shutdown: too low pressure in the high pressure system.

This has occurred to me about 5 times now in the past few months, mainly just driving easy around my neighborhood. This last time on the highway and luckily I was able to coast off an exit.

Is this EKPS LPFP control module issue? If so is it programming issue or does it require replacement? If replaced with a new one is it PNP or does it require programming?

Thanks in advance for your help.
Derek

Where did you get the LPFP?

How does the car behave after at WOT?

Car drives perfectly all the time and WOT never has issues.. This error and shutoff occurs randomly and I cannot associate it with anything in particular. I’ve had the 450 installed for a few months now, I daily drive the car and the shutoff has happened maybe 5 times total. 3 of the 5 occurred from short trips 10-15min or so in my neighborhood. Does not seem to be associated with WOT or aggressive driving. I’ve never had it cut off while WOT.

Hey Dave,

Just after you mentioned it, it crashed on a WOT pull (first time this has occurred)! You can see the HPFP crash when the LPFP cuts off. Do you think this is EKPS?

I've been having the same isssue although I cannot start my car at all, won't run. I changed out my LPFP assembly with the Walbro and re-installed my stock pump assembly and it ran good for about 2 days then the issue popped up again. I'm changing my HPFP and the injectors this weekend.

Here is the sequence of events for me:

5/22 Message:
Fuel Supply
- Full drive performance not available
- Drive moderately. Consult service center

The low reserve fuel light had just come on about 1 min earlier, 49 miles left. I always run to this level and then fill with a mixture of 93 oct and e85 to give me about e50. The above message popped up and the car lost power and ran really rough. I pulled into an alley and the car died. I then got a Drivetrain Malfunction message but I think that was a result of the above message.

I've been running the Walbro 450 in there since last summer with no issues.

5/24
2 days after changing my LPFP back to the stock unit I was driving on the highway heading out for beer and fish for dinner and my car died again. The first time, 2 days earlier, I had code 11A002A Fuel Pressure Below Target.
This time I got the codes 110001 Cylinder injection shutdown: too low pressure in the high pressure system, 11A002 Fuel pressure below target and 11A031 No Description Found.

Could be the Ekp...

Have you swapped back to an oem LPFP to see if itís an upgraded hardware issue

I have not swapped back to oem LPFP yet. The Walbro 450 and sock were brand new when installed. Just happened again, but I got a different code this time. 119001 Rail Sensor short circuit +. Car died and I pulled to side of the road. It would not immediately restart (per usual). I turned the ignition off for 3-4 minutes and then it started right up and drove fine afterwards.

Try & capture a log

I looked at your old log & it just tanks. Makes me think 1 of 3 things

Bad hpfp
Bad LPFP (not super likely seeing hardware is new- assuming installed coreect)
Failing EKP

Has anyone ever looked inside an EKP module? I have not myself but it seems to me it would either work or not work, could it work on and off? Not sure the failure mode in the EKP module.

Did not start happening until after the LPFP install. It is that or the EKP. It occurs most of the time normal driving, not WOT.

Do you have any of the LPFP Socks for the factory pump in 535i F10? Mine got tossed when I put in the Walbro 450 and I used the sock from that install kit. I'd like to have the OEM sock and put factory pump in to diagnose.

I put my OEM pump back in Saturday and so far so good. Time will tell.

This sounds like it is the EKP fuel module. I experienced identical issues some years ago and wrote a lengthy post about it. I replaced it and set it on a small heat sink. No issue since.
Basically the Walbro has a higher amp draw which generates excessive heat. Causes the signal from the EKP to be compromised, ECU then shuts off both pumps and ignition. Once the EKP module cools off after 5-10 min car starts and drives again. Until heat builds up, repeat cycle.
Its located in trunk near gas filler. Peal side cloth aside and you see it mounted on inside. It has a metal plate for heat sink. Mount the new one on a heat sink with fins. I used a 4x4" aluminum heat sink. Have had zero issues since.

Thank you for the info! I remembered reading your post a while back but I couldn't find it again. With mine it won't run even after cooling. I'm changing the HPFP and I know it's very likely i will have to change the EKP ultimately. I will add a heat sink if I do.

No issues with the OEM pump installed. Logs look good too, seems that the factory pump is supplying enough fuel for my setup on PS2 + PI on E40. I didn't even need an upgraded pump. Of course I have boost turned down in upper RPMs because it tapers and I don't want to run at 100% WGDC.

Fuel pressure looks good in the log to me! Bit of over boosting but WGDC can learn down to resolve that.
