But....LOL!!!!!
 

When the engine reaches idle speed, the governor is then "in control" and adjusts the fuel rack accordingly.......to maintain idle speed......

Over time.......the levers within the governor have pivot points with bushings and pins wear, and spring tension/compression relax.....when wear gets excessive and control becomes erratic or unadjustable.....then a trip to the FI Shop is in order.

I was incorrect earlier. Holding the pedal down while starting WILL make a difference.

OM617.95 FSM pages 07.18-010/3 through 07.18-010/5

So, apparently, you must "set" the rack to full fuel by pressing the pedal down.........once. It then remains at full fuel until the engine reaches idle speed.

From my Owner's Manual:

At ambient temperatures below 0*C/32*F and with the engine cold, completely depress the accelerator while starting. Actuate starter until the engine fires regularly and the engine speed rises. Then ease off the accelerator slowly. Cranking times of up to one minute will not do any harm to the starter.

At ambient temperatures of less than -20*C/-4*F, depress the accelerator three times prior to starting.

What do the 3 pumps of the accelerator do?

That's the part that I don't fully understand.

If the rack is set to fully open after one press on the pedal, what's the purpose of holding the pedal fully to the floor while starting.

The explanation of the IP operation doesn't match the procedure as stated in the owner's manuals.
