BMW Crank, No Start Troubleshooting - BMW N55 Engine Rebuild Project Part 10
HTML-код
- Опубликовано: 1 июл 2021
- After months of work rebuilding the engine and a few days of installing it; this BMW N55 engine would crank, but not start. This crank, no start issue took me way more time to figure out than I was expecting as I was trying absolutely everything I could think of. Knowing that the engine needs air, fuel, spark and compression to fire up, I investigate each area one at a time and after seeing that the engine had everything it needed but wouldn't start, I was about to give up. Of course, there was a lot of other items to finish on the car while I was looking for a solution, so I installed the front axles, filled the differential and transfer case with fluid and then finally it came to me! Watch the video to the end to see what was causing this engine not to start all this time.

I was able to get my 135i started this week after using your videos as a rough guide. This was my first time rebuilding an engine and these videos were extremely helpful especially since newtis is no longer available. Really appreciate you filming everything. I wouldn't have the patience!
wow. you didn't record any of it?
Congratulation ! newtis is offline yes, but it's not difficult to find & install ISTA ;)
Congrats man I’m currently doing a rebuild now how’s your car now
Great video
Glad you found the problem! This weekend will be the first start of my N55 rebuild. I will keep this in mind if i have the same issue. Hopefully I don't. Awesome videos man, funny to see someone doing the same project at the same time as me lol!
I'm subscribed and will continue to remove my N55 from my 2011 535i. I left it last fall as winters are cold in Canada and no heated garage. Im at the part to remove the starter and transmission bolts. My son suggested keeping the transmission attached but we'll see how it goes. I, like you, love the challenge and it is so rewarding when after all efforts, you have a great running engine. So much learned so far. Thanks for your detailed work.
Nice, congrats! Very glad you finally got it running, great job rebuilding this engine!
Oh wow!! That's a lot of patience and perseverance in getting a solution. Well done on not giving up! Can't wait to see the next development
There were definitely a few times where I was ready to call a truck and get rid of it, no going to lie, but at the end I’ve learned a ton and this is what it’s all about. I’m just glad this isn’t my daily driver or a car I ‘need’. Thanks for watching!
@@SimpleCarGuyI am on the way to do that, you can bet
if there was a ever a role model for patience…. wow! this is such a fun and interesting project - I can’t wait for the next video!
Thank you so much! This was definitely a marathon rather than a sprint, but she works!!
Ohhhh yeah, great video and a great series in general. I loved following the entire thing and watched all 10 videos!
Thanks for watching!!
Wow I can’t believe you finally got everything working. I was actually thinking about your vehicle and how you’re making out today so I came in from outside just to check to see if there was an update with your vehicle. I must’ve missed this from a week or or so ago. Anyway, it’s so amazing that you got it running but also even more importantly for all of us is to make absolutely sureWe double and triple check things. I have done something like this as well, and it cost me over 40 hours on a project. Anyway I’m so happy you got it running. Have a good day😁
Now that I have the experience, I think I could do a much better and thorough job when rebuilding an engine. It was just so much to learn and a lot of it on the spot that it's easy to overlook. Not to mention, I tried to film as much as I could and that takes your mind away from the job at hand, but I'm glad I did it! Have a great day and hope to see you in more videos.
Great job !!! I been shituation like this before and 9 out of 10 will give up but people like you inspire us all to NEVER GIVE UP....
Thank you! A few times I was at a point where I just wanted to tow the car to a mechanic, but it didn't feel right!
You are not alone I been there. Men like you and me has too big eagles to give up. For me I always think everyone (mostly) has 2 hands 2 feet head and a brain(mostly). If someone can do something I cannot do, they I just admit defeat and admit there is another person better then me. I ALWAYS SAY I AM NOT THE BEST BUT NO ONE IS BETTER THEN ME.
What an epic build !! congrats
Thank you! It definitely wasn't as simple as it seemed at first, but all worth it at the end!
Lol you got the thing going, i watched all the series, good job man !!!!!!!!!!!!!!!!
Appreciate you following this project!! It took some time for sure, but at least it runs now!!
I’m very impressed! Great job!
Thank you!
Great job getting the car started.
Thanks! It was a lot of work, but it's nice to have it running again!
Nicee. Great job!
I have you videos on replay all the time sitting in my shed rebuilding my n55 😂 your awesome!!!(2012 F10 535i xdrive)
Good luck, my friend! Let us know how it turns out and I hope the videos help a bit through the process.
YOOOO LETS GO congrats!!
I felt happier than you when your engine started after the cranking 😂😂😂.
This is so satisfying and I hope to learn more from your videos
I was supppppper happy!! I just didn’t get it on video
You have given me the courage to rebuild mine
That's awesome, go for it!!
Wow!!! Way to go.
You my friend are Amazing...
Nice Video
Thanks for watching!
Success 🎉
Perseverance!!!!
What was the name of the scan tool you used the one that had red on it
glad you fogured it out, i did that on my porsche carrera engine. luckily i could drop the engine out in an hour.
Hi it's possible to replace chain tennisioner without use engine locks ?
Hi i was doing n20 320i timing everything is right it cranks but no start i dont know what mistakes i did or maybe its wiring
Very inspirational! Glad you found the problem.
How much in total did you spend on this rebuild minus do you have a price list?
Wow!!! I feel frustrated when mine was not atarting too. Congrats!!!
It's a terrible feeling after so much work when it doesn't start. Just happy this one strung into life!
Hello, I have a similar problem with my n55 does not start, it went out while driving. Engine turns valves look good, inlet channels are but not to open was that also the case with you? Would be happy for any help
Great Job . I have bought forum US x5 with early n55 without keyfob and i’m waiting to get It and check .
Haw looks like current oil consampion ? Any issieues ? Haw many km did you done after repair ? Regards !
Do the n54 have a (EGR) value?
Hello how can I program my fuel injectors I have 13 740li n55
I just ha my N55 rebuilt by a shop in Florida. I put it in the car (2013 F30) and it cranks with no start. The shop said the valvetronic sensor needs to be programed. Is this true. I initially got codes for the timing off on both cams, no i have one DME code 213A21 (low voltage) and a couple of P codes P1338 and 1339 for the cam positions sensors out of phase. Do you know what I need to do to try to get this running? I'd appreciate any advice. Thank YOu!
Hey brother, I have a 2014 435i N55, I recently locked up my motor and I’m purchasing a new one soon, anything I have to look out for when installing the new engine? Such as reprogamming the battery or system?
Bro I get so impatient I feel like such a failure that I start to doubt myself though with a lil bit of patience and understanding I feel like how did I not see the bigger picture afterwards it was so simple...on any project working on these cars its just the process of finding the solution that gets to me rather then being taught and already knowing ... I do all my mechanical work so I learn as I go along and I've just begun feeling comfortable enough to work on my engine..
Do this car still runing? And if it do are there any problems with reliability? And how much was the total of that engine rebulid?
Hi Great video, I have an issue hope you can help me I have a 2011 x6 3.0, recently did some maintenance work on the vehicle and now it won’t crank or start and smoke is coming from the starter, do you have any Ideas what the issues could be
I'm almost done with my n55 rebuild it's a rear wheel drive thank heavens. I've replaced the crankshaft from BMW $$$ oil pump $$$ All parts from BMW. As for me i didn't loosen cam sprocket. I try to keep old front and rear main seals to use on install. Your videos hepled as this is my first BMW rebuild hope it's my last thanks again take care
Did you make a first drive video after the repair? Is it driving now?
I have a 2011 BMW 535i with hydrolocked engine. I changed spark plugs, removed water from pistons with vacuum, changed oil (oil had water), removed water from manifold and charger hoses. I changed the engine starter because when I test bench it, it didn't work, so I thought that was the problem. The engine doesn't even crank at all. Do you have any recommendation? what are the chances that the engine can be salvaged. It has about 93,000 miles.
I have a 2011 BMW 535i, N55 engine. I removed the valve cover, and turned the engine manually to check the timing chain. I changed the spark plugs for new ones (properly gapped of course). I changed the VANOS solenoids for new ones too. re installed the valve cover, put in engine oil. and had the same problem. Engine cranks but no start. I'd have to check it out.
congratulation , I'm happy and proud you fixed your car , it's a nice video to learn how to do it .
what exactly you are using to diagnose the car , are u happy with it ? multiscope too?
Thanks!!
I've mostly used my ThinkTool Mini diagnostics system ( I have video on it). It does pretty much everything a dealership's tool would do as far as diagnostics. Multiscope was useless, but I wanted to learn how to use it.
Hi, i need help with my car problem, the problem is my car crank but won't start, i checked injector signal, there's no signal, i checked ignition coil, there's also no signal, then i checked all fuse and relay, there's no fault. After that i checked all the wiring on engine, there's no problem with the wire harness, lastly i checked the ecm/ecu, i bring it to ecu repair shop they checked no faulty and i pay charge for checking usd60, after that, i try to start again, its still won't start, then i bring the ecm/ecu again to the bmw agent for checking with charge usd100, they also said there's no faulty with the ecu/ecm. I checked the fuel pump its working, i checked the pressure of fuelpump its working perfect. I checked the immobiliser, also no problem, Im still wondering with the problem and why my ignition coil and injector no power and no signal. Fault code on obd is P0341, P101b and P1061 , i tried clear, after a few minutes its appear again, anyone know what the problem? My car BMW 320i E90 2006, engine N46
Oh waow ! A lot of research to make it start but that's how we learn.
You've been lucky somehow. So if I understand, off-timed by 180° doesn't make any mechanical damages.
Upper engine was in exhaust while the lower engine in compression ? (so the Intake & explosion).
Too bad it doesn't show any code :/
Question, do you have to replace the vanos bolts ?
I’m on this point too, thanks for your video always help me, question; on minute 17:40 did you just rotate the camshaft yellow thing 180• to fit correctly on timing tool? So that’s mean the sensor read the rotation of the little yello camshaft cap (don’t know name of it) I will appreciate it your reply 🙏🏽
Name it as Camshaft Position Sensor Impulse Wheel (yellow thing)
How long did you prime the engine before adding fuel and spark?
I ran the functions using my ThinkTool Mini that primed the engine. It turned off the spark and cranked it for about 15-20 seconds.
Hello my friend I have the same car nice car bro grand total how much you pay thank you ?
Thank you so much for this video, I have question what year is this car ? And from where did bought the new Turbocharger from BMW dealer ???
This is a 2011 BMW 335i. I did not buy a new turbo, it's the old one that came with the car.
@@SimpleCarGuy I thought I heard you say a new one in the video?
@@SimpleCarGuy So question did you fixed the old Turbocharger ???
So the QR codes need to be facing upwards correct?
That is correct.
Mate how are you going with the N55. All running well? No problems?
Hi! Yes, been driving it after finishing the rebuild. All good!
Nice work on your build bro! I have a 2011 N55 with a failing crankshaft sensor and after replacing the sensor with multiple new ones there has been no start conditions after trying 3 new ones! Put the old one in and it started! Frustrating to say the least. Still looking into possible part number difference on years. If anyone has experienced this please HMU.
There, I've been told only OEM are working. The gap for the hall-effet is critical. A bit too far away from the target and engine won't start.
@@stephanelouvet1113, We found my issue which was the reluctor wheel had a chip in the magnet. Had to drop my trans, remove the clutch and replace the reluctor. Everything worked like a charm after that. The hardest thing we've ever diagnosed because everything pointed to the sensor. The sensor was in fact broken because it was what touched the reluctor wheel.
Ground goes behind head
I figured that out later on, forgot to mention in the video. Thanks for watching!
Probably timing chain job was not correct.
Lmaoo can I ship you my n55 to rebuild it seized on me 🤦♂️
lol, i wish I could do this more often, but man is it a process when you don't do this professionally.
N55 once they spin a bearing pretty much unusable, better off getting a used one from someone parting one out
