    Strange problem starting this A.M.

    Had the car out last night. Got gas. Parked it in the garage.

    This morning when I got it, I turned the key to start it. She turned over and over and over...but would not catch. Plenty of juice from the battery. I tried over and over. It got below freezing last night (maybe 29 degrees) but was about 35 degrees when I was trying to start it. It seemed like a fuel issue - I didn't smell any fuel after a few minutes of cranking. I opened the gas cap and put it back on (possibly thinking it was vapor-locked or something). I had tried fluttering the gas pedal and still nothing.

    My last attempt I had just floored the gas pedal before cranking and then she fired right up.

    No codes, no stumbling, no issues whatsoever.

    Bits:
    I could hear the fuel pump priming up.
    I just changed the fuel filter this past spring.

    Any thoughts?

    There are a few things to try...

    Good day,

    It is either spark or fuel (either too much or not enough of one or both)... In this case it sounds like you have loss of spark at first, but when it does return, the motor is flooded... Your IRV (idle regulating valve) could be stuck in a more closed position not allowing sufficient air into the motor...

    I'd keep pushing the gas pedal down a little while trying to start it, then letting off quickly to see if the IRV catches up with the motor, or if it dies... Clean the IRV if the problem persists and go from there...

    Let us know what you find out...

    Cheers and happy holidays!!

    What model of 3 series? what year? mileage?
    Recent maintenance?

    Plenty of electrical things that can cause a no start on a BMW.
    Mine is currently having cold start issues where the Throttle Motor isn't playing nice. But that's not the place to start looking.

    I it cold dependent? did it start when it warmed up a bit?
