825I hard start after first start in morning.
My 2011 825i (1035 hours) started having some confusingstarting issues. After sitting overnight the Gator starts right up, but after that throughout the day it has along crank in order to get it to start, sometimes it will not start withoutgiving it a little gas. After giving itsome throttle it runs rough for a couple of seconds but then smooths out andruns fine. I gets used on the farm every day for chores so I dont anticipate an old gas problem.
Actions taken up to this point with no change:
Ran some Sea Foam in the lasttank of gas.
Replaced fuel filter.
Ran a tank of fresh 91 Octanethrough it.
Changed the spark plugs.
Changed the Air Filter.
Cleaned the spark arrestor onthe exhaust.
Ran it with the gas cap looseto eliminate a vent error.
I did not conduct a Fuel Pump pressure test yet, I assumedthat the pump is not leaking down since it starts perfectly after sitting overnight,and displays the hard start within minutes of shutting it off.
I have the Shop Manual and reviewed the trouble shootingguides but nothing seems to jump out at me as a logical next step, at thispoint I am a loss for what to try next. Idont want to just start throwing parts at it (TMAP, ECM, Oxygen sensor, etc)since it runs fine after it is started and starts fine first thing in themorning.
Any suggestions/guidance is greatly appreciated.
