Why do I have a hard time starting my 328xi

Asked by JohnnyBMW328 Oct 06, 2020 at 01:46 PM about the 2010 BMW 3 Series 328i xDrive Wagon AWD

Question type: Maintenance & Repair

The longer the vehicle sits without running, the harder it is to start. After sitting overnight, the first attempt to start it in the morning takes 4 or 5 tries. The engine fires up, sounds normal, then shuts down. Sometimes the starter will keep cranking for a few seconds. I wait a bit, try again, and have to do that 4 or 5 times before it stays running. Runs perfectly after that and starts right up the rest of the day. If I run the engine around 11 PM for a few minutes, it shortens the number of tries in the morning to 2 instead of 5.  Any ideas??

Sounds like fuel. if there is a leak then air will replace fuel, slowly so you can fire up until the air is replaced. It will be a small leak but if you've had any work done recently, that's a red flag. Probably on the low pressure side. I admit I don't know your car even having owned twp BMs
