2004 325i Wont start D:

Hey there guys,
So lately my car has had a problem starting in the morning, it would start then stall, but on the second start up it would be good to go, this happened a few times and I thought nothing of it because of the extreme cold we have been experiencing in Base Borden, may be entirely related or entirely unrelated..

I drove to the grocery store with my wifey then back to my house and there was no issues, right at my driveway I slow down to go over the curb and my car losses all power and then stalls. I go to try and turn it back on and no luck, i can hear the crank turning but no spark, I tried 3 or 4 times and eventual it stated again, sputtering and i push the gas and it does up but it was still sputtering, and sure enough it dies again.

I pushed it back into the driveway with my buddies and began to try and isolate the issue.

1) First I assumed it may be the fuel pump, but i had my wife turn the key while I listened inside the gas tank and it made the 4 second primer hiss, so i ruled the fuel pump out.

2) After doing a bunch of research trying to find the issue/similar issue online, and I came to think it maybe the Camshaft Position Sensor (not sure if intake or exhaust), but here's the sitch to that, no codes. At all...

3) Maybe somehow the battery got f***ed, so i grabbed my booster cables and my truck and sure enough trying to boost it did nothing. (I've had power this entire time, electrical power still maintains when i put the key in)

4) Unplugged the MAF and tried starting it, identical results as per before, so MAF is ruled out.

So end result is that it wont start, i still have power, crank is moving, fuel pump hisses and im rather lost, also im tight on cash so I rather not take it to a shop (christmas and what not...)

Any ideas? Any ideas on other things I can examine to help diagnose my circumstance?

I bumped the car up and down and there was gas swishing back and forth.
So I assume theres enugh gas. Ive never had a issue with the gauge, and since the last time I put the gas in it the gauge reads approximatly what it should.

Man its funny you say that, I had a suspicion about that, so I put a bunch of gas line anti-freeze in the tank and put 5 litres. It didn't start, so I took the cover of my engine and used a blow dryer on the fuel rail. Started up like a beauty so I drove to the gas station and filled it up! Good to go.

Holy crap! Way to go!

Btw... This type of issue wouldn't be isolated to an e46. Next time you might consider posting in the general forum to get a larger audience.

Glad you got it going... the fuel pumps do sometimes slowly fail, so you could have reduced pressure. How many KMs and has it ever been replaced? Other thing I was gonna mention is the CCV failure which also happens to all E46 at some point. Botht he pump and CCV fail between 100K-180K km.

195km, I bought the bimmer at 145ish. Since its been mine, neither of those things have been replaced. I really don't know if they were replaced prior to me owning it. :|

Well, if I were you I would replace the fuel pump, filter, and CCV preventatively, espcially since you're in a very cold climate.
