Car hasn't been firing up on the first turn of the key recently, smell of unburned fuel. Will usually start the second time and idle is slightly lumpy though the tach doesn't bounce at all. AFM issue?

Need a bit more info really...

Does it fail to start from hot or cold, does it always take two goes to start?
Does it only play up if left overnight?

If you drive the car, pull over, shut it down, wait 30 seconds and restart will it catch?

Smell of fuel suggests fuel leak.

I would start by inspecting the fuel lines throughout and whilst there change the fuel filter.

Best regards,

Alan.

Check the fuel pressure regulator.
