MBZ, as all other cars w auto-trans, start in Neutral or Park. This is accomplished by a neutral-safety switch, which is located on the linkage-side of the transmission. If it ever gets out of adjustment, you'll know by reverse selection and starting problems.

Pumping is normal for a carbureted engine (acclerator pump in carb). W/FI, the only thing you may have to do is hold the the pedal down an inch or so while starting. If your FI is tuned correctly, just turn the key and watch it start.
