  3. Crank cut after a second

    General E46 Forum
    On my '03 325ci tonight my car cranked for just a second then the car cut the crank and all i heard was the fuel pump. I turned the key back off and then on again and the car started right up. I feel like its probably my crank sensor going bad but my question is if the crank sensor is going bad...

  7. No start - VERY intermittent

    General E46 Forum
    This morning I stopped for coffee, and when I returned to the car and turned the key, the starter didn't respond at all. Dash was fully illuminated, radio worked, and good voltage, it was as though the ignition was not connected to the starter circuit. I pop-started it - take that...
  8. 1999 323i. Overheated and now refuses to even crank.

    General E46 Forum
    Hi all, I've done plenty of searching, but I've failed to find someone with the exact same situation as me. Basically, one day, shortly after a cooling system rebuild, the car was unusually hard to start. It took two tries to get it to fire up. I thought nothing of it and proceeded. Later...

    General E46 Forum
    E46 fanatics, I am desperately in need of help. I drove my 02 330i to work and I noticed, it wanted to die for a brief second but still stayed alive. Everything was fine, the car was still running until I parked and turned it off. Once I came back to the car to start it, the engine would crank...

  12. Swapped Spark Plugs and now it won't start

    General E46 Forum
    This morning, I sent my brother to go grab spark plugs for our 2004 325xi. We swapped them following a tutorial step by step (I've also done the same procedure on another E46 with no problems) Long story short turns out we didn't have the correct plugs. What made me realize this was the fact...

    General E46 Forum
    Alright guys this has me stumped. Two days ago I was doing a compression test on the E36 in my Sig to check the health of the 350k mile motor and all was going as usual. To my surprise, I had consistent excellent numbers across the board. After putting everything back together I went to start...
  19. 2002 325i no start - possibly a bad starter

    General E46 Forum
    So this problem started a few weeks ago. When I turn the key, I hear one click and nothing else. I brought my 2 year old battery into Batteries Plus to get it tested and they said it was working like new. This lead me to believe that I have a bad starter. I understand that generally a bad...
