Hi all,

I've been searching on here fro similar problem but haven't really found the answer. I was driving my 2007 335i e90 and accelerated on a two line road when my car started sputtering and losing power. felt like the engine was missing and running rough. I was far from home so drove it about 20miles a parked car. got back in the car to start it up and car started with rough idle, put car in gear and it died out. since then it hasn't been able to start. I had a friend pull the codes from my car but he accidently erased them. I think it had 11 codes altogether. He hooked up the scan tool again and tried starting and the code P0341 showed up which refers to the camshaft sensor. I order the part and replaced it, erased the code and started the car. Still same problem. p0341 code pops up. I then took out the vanos solenoid and cleaned them because a read somewhere in here that it could be the problem. I also replaced all my spark plugs and then restarted the car, still same problem. Car will crank long but will not start up. PLEASE HELP ME. I'm stuck and my car isn't running. anyone got information? thanks in advance. any direction or links that you know of will be greatly appreciated.

thanks

How Many K on your Car?
when were Coils replaced last?
when was a walnut blast done last?
Injectors, what gas to you fill with?

Any history of HPFP replacement on your car?

It sounds like something in the Ignition cycle.... Plugs, Coils, Intake Port, Vanos.
but that LONG Crank has got me guessing.

also that code p0341, I don't know if I would pay attention to it since it is not starting.

Injectors, cheap idea....but you need a Running car..... go put Chevron Premium with Techron for a tank and run it.

Coils is the number one culprit right now..... my guess.

Hi,

Thanks for the quick reply. I have roughly around 93kmiles, I just changed coils 1 year ago, no walnut blast done since I had it, but I took apart the intake to change out my starter and look inside and it was a little dirty. thinking about ordering my own kit to do it. didn't replace injectors, and I only use premium gas. I bought the car second hand and don't know if the HPFP replaced. I read up about it in here. I also took out both vanos and cleaned it with break clean etc... and reinstalled it, even swapped sides on vanos. I also read that I would need to program the injectors if I change it out? don't have the tools yet to do it. will need to read up on here to see how to do it. any guess. I just changed out my CRANKSHAFT sensor also and only took 10mins to do, hoping it will start but still long cranking no starting and the half yellow engine light is on. still pulling the p0341 code. I lost and puzzled ugh. HELP! THANKS in advance

You need a BMW shop or someone with a coding set up (INPA or Carly) to read the BMW specific errors and find out exactly what's wrong. A generic OBD2 reader won't cut it.

Hi,

Thanks for the reply. unfortunately we don't have a BMW dealer on the island that I live on. I've only got a FOXWELL can OBDII &EOBD code reader. Anyway else to read the codes? been reading so many different scenarios.

[RocketSurgeon]

Ok, lots of codes won't set unless the car is running. Generic code readers really suck on BMW since they don't pull the more specialized codes, and have inaccurate descriptions. The Foxwell is good, but I think you might have to do this the old fashioned way. See if you can read off fuel pressure while you crank. Pull a spark plug to see if you are getting spark. Avoid starting fluid or prolonged cranking. If you have fuel pressure and spark, you should run a compression test to make sure everything is cool. If you still come up empty handed, pull the valve cover and have a peak inside. I bought my 2007 335i as a crank/no start. Ended up being a broken intake camshaft, but that is super rare.
Get yourself set up with a K+DCAN cable (green circuit board and switch, $20) and Rheingold. That's dealer level software that you can get for free.

Thanks for replying to my post, much appreciated. Checking for spark the old fashion way was my next thought and step. I will be doing that when I get home from work. I'm hoping I don't drain my battery from all this testing. was looking into getting a cable. will search for where I can buy one, possibly amazon? looked into the link you sent and saw several versions, do I download the Rheingold file? thanks you so much for helping. will update as I go on to figure this out. also was reading about the HPFP and recall for my year 2007 N54 model. I have that half yellow engine light on when cranking with long crank...

DarkNemesis

can you elaborate more on this? what do you mean? where can I get a standard tool set up on my laptop?

let me know. I'm willing to look into anything at this point. any help is appreciated. thank you.

This sounds similar to a problem I had with my DME, although mine started up, it sounds just like what you're describing. I would test the Mosfets. Also long crank, and not starting sounds like HPFP.

@Dmoney;22395890

Hi,
I took apart my DME(ecu) from my car today and tested all those Mosfets and all of them were ok, so I guess its not that. tomorrow I will be testing a the coil to see if I'm getting spark to my plugs. if I am, I can then narrow it down towards that HPFP? Also I was reading on here that there is a recall for that HPFP? for my year make and model? anyone know? please chime in. is there any other way to test to see if I'm getting fuel to my injectors so I can also rule out the HPFP? any help is appreciated. I hope to find the culprit of this problem and do a write up so anyone else going through this wont suffer much lol. help

The recall was for 10 years 100,000 miles, What was the in-service date for your car? if it was 11/07 or 12/07 I think you're still good, granted you'll have to be under 100,000 miles.

[racermp]

What's the fuel pressure when u try to crank? Definitely sounds like fp

@racermp
Do you know anyway to check for fuel pressure on this car? I am searching on here for ways to check for pressure to injectors etc... or how can I check to see if the HPFP is working properly?

v/r

so while running I use apps like mhd or torque or Carly.

when the car is off, u should get 50-70 psi from lpfp when cranking , should see the pressure slowly rise a bit.

when I got home from work last night, I checked for spark by taking out coil pack and leaving wire connector on. I then used a screw driver and wire to run close to body ground bolt, cracked the car over and didn't see any spark jumping across from wire to body ground. I then went to the next coil pack and did the same test, I got the same result. Is it possible that I didn't do this test right? Can I take of the coil pack and check for ohm reading on the pins? will that work to check coils to see if it is working properly? in the mean time, I ordered a inpa k dcan cable from amazon and am waiting for this to coming so I can download the software onto my laptop and run test. I know that one post above gave me a site for software download, any other good ones you can suggest? I am new to this so forgive me if im doing newbie mistakes.

car still cranks over long but wont start. car also has limp mode light (yellow engine with half of it colored yellow) still returning p0341 code.
work done after car didn't start
1)changed camshaft sensor
2)changed crankshaft sensor
3)took out both vanos and cleaned with brake fluid and reinstalled swapping positions
4)changed new spark plugs
5)checked for spark at coil-----no spark on coil with coil out, wire connector on and screw driver with wire close to body ground to see spark
6)check DME mosfets all test good

puzzled HELP HELP.

[BashShah]

P0341 is most likely an electrical issue.

go to dealer

Long crank definitely sounds like HPFP.
Download BMW logger to read codes easiest.
Install ISTA-D is harder but will give you best results for codes. MHD is also great for reading codes but costs more, so I'd do another method unless you also want to add MHD tune. You can pm me if you have questions.

thank you for responding, I have sent you a PM for more information on this. thanks again.

question. will a kdcan cable work with what you are describing?

Mhd is free to read codes. Free.

Great tip, I had no idea. Much easier to use MHD with cable than set up ISTA-D !!!
