2011 N52n No start, HELP

wboro4 · 11-28-2012, 12:43 PM

Here is the story, i have a 2011 328xi n52 that was involved in a front end crash and now will not start. Everything powers up, it just cranks and cranks.. I noticed there is no fuel coming into the fuel rail but i can hear the pump prime in the back. I can get it to start with starting fluid but immediatly conks out since lack of fuel. Any thoughts or ideas? I even pulled the valve cover and made sure everything was in time with timing tools. Thank you for any help you guys can give me.

Fuel cutoff from the collision? Maybe a crimp in the line? It could be many things based on extent of damage, or something so simple we will never guess!

Is there such a thing as a crash computer that would have to be unlocked? Somewhat like a safety feature, I.e. preventing damage to the engine/car? Fuel lines look ok, I don't see any breaks or crimps. Could it be possible even though I hear the pump maybe the reg is bad in it and is not producing enough pressure to push it to the rail?

Disconnect the IBS (Intelligent Battery Sensor) and try to start the car. The blue connector on the right

did this work? Just curious.

That did not work, still pulling my hair out.

At least get someone with INPA on a laptop to read the codes, if not you are going to go down a long guessing road.

Check your fuses sir. I've had many 2010+ n52s pop the fuses in a front end impact. Not sure which ones they were but I've seen it. Also check
Your vanos solenoid plugs for damage.

wboro4 · 12-08-2012, 06:00 PM

Fuses all seem to be good in the glove box, solenoid plugs also seem to be ok. I will have to try and find someone with some diagnostic software for BMW that can run live data.

How about an inertia switch? Cuts fuel in the event of an accident.

wboro4 · 12-09-2012, 08:03 AM

Can anyone confirm that the e90 has a fuel cutoff and if so where it is located? I can't seem to come up with anything in the search.
