[BMWRT444]

Was driving down the road and all of a sudden the bmw stopped. Got it to my garage and fault codes are p0030, p0091 and p1252. Engine will not restart just cranking.

Rev counter bounces when cranking and car runs on easy start. Removed rear seat and pump works when i put a power probe on it but dose not prime on its own.

Changed the fuel filter undernear and no desiel there when cranking. Read some stuff online and tried bleed the fuel system but nothing.

Tested the fuel pressure regulater on the end of the fuel rail and voltages are 0v, 0.5v and 5v which ive read online and thats fine. Thinking it might be the fuel modual..... any help on what to test/check next would be appreciated!

Next step is to swap in an N52B30

I was driving down the road today In my 2007 e90 320d and it just cut out it’s auto but was still rolling in drive I pushed into reverse by accident which had no affect at all which looking back at now I’m really confused but I put it into nutural and rolled to a stop the car showed me the engine light but it just cranks that’s it it won’t start at all. Any ideas? Cars done 102k its due a service so but not overly due has anyone else had this problem?

LOL sorry I have no advice for either of you. The N52 swap seems to make sense

OP: If you can look up what those codes mean and edit your original post to include it, that would help. They are just generic codes though. If you hook up a BMW scan tool, you'll get much more specific (and therefore useful) codes.
