[QUOTE="btslee, post: 34602, member: 32079"] I have been an avid follower of this E46 forum prior to getting my E46 earlier this year. Recently, my car has developed a peculiar problem. It would become extremely difficult to start when cold (in the mornings) and would only start after 4-5 cranks. Subsequent immediate starts after the engine has been turned off would be fine, but if the car is left for 5 minutes or so, it would become difficult to start again (would only start after 2-3 cranks).Initially, the fuel pump was the suspect so it was replaced. I have since replaced the fuel filter (which comes with the pressure regulator), throttle body and alternator pulley. I have also changed all 4 spark plugs to yttrium spark plugs, done an engine flush with new Ravenol 5W-40 and an oil filter.

Other parts which may/may not relate to the problem and which I have replaced include the Oil Sump Gasket, Oil Sump Plug, Air Flow Bellow, Engine & Gear Box Mounting, Valve Cover Gasket, Oil Filter Housing Gasket, Oil Cooler Housing Gasket, Oil Pan Gasket and Gear Selector Shaft Seal.
