BMW N54 E92 335i HPFP Install: DID NOT GO TO PLAN....

[@ZijkantLeutn]

Fuel level sensor got "stuck" in certain position after installing the upgraded fuel pump and you ran out of gas...? :-)

[@pulsechainpete3808]

That's so funny, especially with the price of fuel ATM☺

@@pulsechainpete3808 Absolute classic. Good sport for showing us all, made for a really entertaining vid

[@1Sturdy5_]

Lmao 😂

[@MrLaloman18]

at the begging of the video I can clearly see the "FP_L" which stands for "Fuel Pressure Low" or "Low Pressure Fuel Sensor" and from what I understand that the LPFS must keep a steady 72psi at almost all times, anything below it means the Low Pressure Fuel Sensor is failing hence why many get Low pressure codes, the car goes into limp-mode after accelerating faster and also get a "Drive-train Malfunction" as well codes such as P10D9, P15DF and P0087 all have to do with the Low pressure sensor/high pressure fuel pump but mostly the sensor to start with as the old version of the sensor is well known to fail do to the design and the latest updated version fixes that problem! NOTE: The high pressure fuel pump should idle at 700 psi and go up to near 2500psi at full throttle! It the HPFP idles below the 700psi mark every time after installing the new latest Low Pressure Fuel Sensor/ + fuel line then the HPFP needs to be replace as its a clear sign is on it's way out!

[@chrisrobles2012]

Remember when I said the Venturi is there to fill the bucket? By not using the hydromat you risk damaging the HPFP by going dry. This only happens when you cut the bucket bottom or bypass the Venturi system to suck /fill the bucket to give the pump fuel when the tank is low. As others mentioned , the tank level got stuck so it wouldn’t have been obvious until you did the visual you did at the end.

[@robertsimental1469]

The fuel level float must have got stuck on the lpfp lol. There’s also a fuel level sensor float on the fuel sending unit on the other side of the seat. If the gas tank still isn’t reading correctly check that. Ask me how I know lol.

[@ZeroTo60Tube]

How do you know? hahahah

[@roger9546]

Fun fact, you CAN actually turn off the car whilst driving in neutral and you can also restart it with slight pressure on the brake pedal. I have done it before in my N54 335i.

[@ZeroTo60Tube]

Thats what i thought, but as soon as i saw LPFP hit 15 while i was driving i hit the button, so i didn't run the HPFP dry. I thought the car was off, but it kept running (just).

[@davidereso7624]

😂

[@rickniebla]

You can restart the engine while its still rolling. Just put in neutral and press the engine start button and hold it for a few seconds and it will crank

[@MrLaloman18]

This is the same HPFP that FCPeuro sells.... and I notice something..... The white sticker with bar code shows that the fuel pump is actually the old ass model 13517616194 and NOT the latest upgraded 13517616446 model that the box indicates is.... I know cause i have the same pump from FCP that I just ordered and realized I don't need after since all my car need was replacing the Low Pressure Fuel Sensor to the latest and better upgraded model with the included newer version fuel line it attaches to.... My car was giving the P10D9, P15DF, P0087 & from MHD Flasher error codes 11A401, 11B401, 11B501, 119404 (Rail Pressure sensor, signal: permanently stuck), 11A002, 11AC02 and all of these indicated High pressure fuel too low.... The first P errors lead me straight to the Low pressure fuel sensor and I replaced it with newest latest revision model with the upgraded short fuel line. I finally was able to find an android app that monitors the Low fuel pressure PSI with BimmerLink. Once the new Low Pressure Fuel Sensor w/fuel line installed in my F10 535i M Sport the bad gas smells where gone! But the rough cold starts a 3 to 4 second starting cranks where still there and when warming up the car still felt rough until it warmed up.... At cold starts the High Pressure Fuel pump would have way too low PSI readings at about 100 psi or less and would throw a Drivetrain Malfunction when accelerating normal not fully warmed. I would turn of the car, open the door quick and restart the car and the PSI readings for the hpfp would become normal again at about 715 psi at idle. This continued for a few days and thought to myself that the HPFP was bad and needed to be replaced as well... $700 for the pump with $75 for core change included.... Well told myself, how could both the HPFP and the Low Pressure Fuel Sensor could've gone bad at the exact time when both are electronically connected differently and separately! I started thinking and then it hit me.... "maybe the sensor needs to be reset as the ECU probably still thinks the old sensor is still connected".... But there is not app to reset that sensor and then it hit me..... For all sensor to start reading correctly when replaced you must ignitiate a startup power sequence.... So what I did was without starting my car the next day, I turned on the ignition but NOT the engine, and waited till the light turned on then turned off and the only light module that stays on is the Engine Light. So then I turned OFF the ignition and waited 10 seconds. I repeated this process 3 times.... after finishing the reset I left the car off for about 10 minutes.... I connected BimmerLink and started the car... To my surprised the car started right up on the first crank... the PSI on the Low Pressure Fuel sensor was ready a healthy strong 87 psi and would stay there when idle and driven.... The High Pressure Fuel Pump was at a stable strong 700 -715 psi at idle and would easily go up when being pushed on the gas peddle.... I would keep monitoring all the sensor and psi after clearing all the error codes, and kept testing the car for the next days... took it up on the freeway and did a few pulls and NO Check Engine Lights, No Misfiring, No Drivetrain Malfunction.... NO Problems.... seems the HPFP is indeed still good and the culprit was the Low Pressure Fuel Sensor!

[@BUTTERSOCRAZY]

is the tank empty, was my guess when you were on the side of the road. out of fuel

[@dubsense]

his gauge shows he has just below half a tank. but tank it empty duno what to think.

[@emmanuelenriquez4872]

Currently stranded cus the car kept going into limp mode and would come back after deleting the code as soon as I gave it any gas. It finally stumbled and refused to turn on. I also recently installed a stage 2 fuel pump and had to retro fit the bobber since the bracket holes for the screws didn't line up properly. So this is definitely my issue 👌🏼🤞 thank you for this one

[@IAmDamiani]

If that ever happens again... Disconnect the neg terminal on battery and plug it back in to clear shadow codes and get the car running again. That saved me from calling a tow truck. Also, you many want to flash to 91 oct and then add more 91 oct asap till youn have it looked at. I have done this many any times, believe me. Too much E85 will throw Fuel Pump error / Low Pressure error and stall aka Limp Mode and will not start after that FYI.

[@n54power21]

The German tuners take out the small filter in the pump so that there is more petrol and less resistance, for stage 3 it is advisable to do this. Good luck 👍 HDP is an illness, lasts 50,000 kilometers approx

[@adrianharrison5208]

who does that?

[@brandonrucha3177]

Do they replace the filter by adding a larger inline one with larger flow ?

[@dbnpoldermans4120]

HDP? Hohe Drueck Pumpe? German for HPFP?

[@ZeroTo60Tube]

N54 Power, have you got any more info on that? I remember reading about Vargas doing it on his VTTO seeing some more info on it and at what point its needed etc.

[@adrianharrison5208]

I had not heard about that before but I think I would want to keep any filters that are in the system.. if the system cannot deliver whats needed because of a filter then I would just upgrade it

[@MrLaloman18]

Oh and just a reminder, there's a BMW Fuel Pump recall detailing the failure of the pump, melting harness and the fuel meter needle failing causing false fuel levels making the driver think there is still fuel in the tank when it runs out of fuel and stalling suddenly! This effects N54 engines and early regular N55 engines (not N55 engine M Sport models as these have the higher quality pumps as the M5 series models)...

[@seydouzongo3144]

Bjr, I have a problem with the water pump, when you turn off the engine and take a plug at the appraiser, the water comes out normally, but when the engine is running it's air that is sucked in. I wanted to better understand how it works. Thanks..

[@ZeroTo60Tube]

this was the Jb4 app. You do need a JB4 to use it.

[@bavarianhero]

I just replaced mine, and it worked, less gunkee stuff coming out the exhaust but it still stutters only because I still have index 4,7,9, and 12 injectors. None of them are even but I heard if you have 11 and 12. That’s the only one you can have, and the the rest o my on their own. Is that true?

[@ZeroTo60Tube]

To be honest i am on the fence with the "need" to have index 12. I have seen this be an issue as well. But they are all prone to issues. If money is tight, try and identify which ones are leaking and just replace those.

[@ZeroTo60Tube]

Just a note, different case if you are running big power. Big power where you are maxing the DI, go index 12s.

[@bavarianhero]

@@ZeroTo60Tube I found the best mechanic around my area but I can’t afford to pay him. Last time I went with him he gave me 2 index 12 injectors for free. He let me know which where taking a dump on me, and from there I replaced them as well the seals and couplers. After that he decoded them. The car still ran like crap but way better then before, I replaced the HPFP with an Oasis one. The car runs a lot better, I’m going to take the car to him when I get a chance. I just want to have money saved up this time because I’m always fixing the biggest issue at the moment and those index 4 injectors are holding up pretty well. So far I’ve done everything from Performance Dynamics and your channel, the car has ran a lot better since. I know next time I should try to replace all Injectors and finally do that walnut blast because I used red line and it worked but I still believe I need to drive it a bit more and give it one more oil change before I can say it’s good to go.

[@bavarianhero]

@@ZeroTo60Tube no huge power I still have stock cats. I actually want to see how much more power you can make with just silicone inlets, chargepipe, intercooler, and resonator delete. From your experience with N54s, what do you think that’ll push. My guess is always 375 torque and 335 HP. My goal was to specifically make 420 hp or TQ lol 😶‍🌫️give or take.

[@nathanielrobinson3041]

I experienced the same issue if your lpfp is not right your hpfp system wont be right either to rule that out I would stick another genuine walbro in to replace that cheap primary pump ya have in it lol, I did notice in your previous videos of you lpfp data logging your pressure seems to stay at about 60psi ish witch I would expect to see about a solid 70 psi on average in the end I suspect you old hpfp might be still be fine I would be surprised if your old pump is still upto the task as it's a revised version

[@ZeroTo60Tube]

I might not have mentioned it. But I ended up making the walbro the main pump, for reliability’s sake. It appears the JB4 gauge reads lower than MHD. I had the JB4 disabled while I was playing with the dtml flex input last year and noticed MHD logging listed a higher lpfp number than the JB4. Have you ever come across that?

[@nathanielrobinson3041]

No I haven't as I use MHD flash only and I have got my 17Ts fitted and your in for a surprise with these turbos I haven't yet tuned it and keeping an eye on the tune it pulls like a rocket past 4000rpm thy are just fantastic and the lag is minimal if I'm honest

[@WoodstheGroomer]

Geez the fuel economy has been so good running ethanol and boost......the gauge hasn’t even moved................Bugger! at least you have a spare hpfp now.

[@ZeroTo60Tube]

Man this was so long ago, i honestly cant remember. I know that have been reset many times since. To let you jump through the whole story. A custom tune from JSR is what sorted this car out. It was never happy on the BMS ots maps.

[@motown862000]

Would a failing hpfp cause blue smoke to come out the exhaust and smoke to come out from the oil fill cap on the valve cover?

[@ZeroTo60Tube]

Generally not, but anything is possible. To rule that out, simply montior your rail pressure. Make sure it is behaiving as it should. If the HPFP is failing your rail pressure will be all over the place.

Probably, they bolt to the engine very different. Actually they are driven of a cam type lobe, not a shaft like the N54. That said even with better fuel pressure the N54 high pressure injectors are a limit. Port injection is the only way to make serious power.
