E36 M52 Starting Issue
Discussion
Hi Guys,
An odd one here I hope somebody can help me out on. Annoyingly, I seem to remember seeing a similar thread on here, but I can't remember the outcome and can't seem to find it now...
Last Monday evening, I needed to move the car into a different space so, even though I hate doing this and avoid it if at all possible, I started the car from cold, moved it, then turned the engine off again. I didn't need the car for the rest of the week, so it sat there until Sunday morning when I had to go somewhere.
Cue about three sessions of cranking for about 6-10 seconds (which doesn't sound like much when written down, but seems like an age at the time compared with its normally immediate start - try and imagine it!).
During the last 10 seconds of starter motor activity, it gradually started firing on one, then two, then three cylinders until it settled into a lumpy idle. Eventually it started firing on all 6 and seemed to be entirely back to normal operation.
It's never done this before and has been absolutely fine since, so I can only imagine it was due to the two cold starts in succession which possibly injected sufficient unburned fuel that it caused the sparkers to become saturated?
Any suggestions appreciated! Nothing more embarrassing than offering a lift to people in my P&J, only to sit cranking the damn thing on the drive
Cheers,
T.

They can have a habit of overfuelling from the cold start which renders them useless if you restart soon after switching off etc.
I had this once after moving the car off the drive.
Awesome - so nothing to worry about, hopefully I had this once after moving the car off the drive.
