In reference to the possibility that: (1) the hot non-start affliction may be due to worn shift linkage bushings in the auto tranny (Mike Tangas), and (2) the potential danger of the car lunging forward if inadvertently started via momentary switch while on "D" (David@be459), this car actually has MANUAL tranny. Hence, I have to discount both possibilities.
Well friends, the preferred non-scenic route now is to remove the starter, check solenoid connections, rectify if faulty, and if otherwise, get a Bosch rebuilt replacement (right, Larry?). THAT was the easy part. Now, how do you go about extricating the starter from the M110? From a top visual, I can see the starter cosily embedded amidst the exhaust manifold or some other heavy-duty stuff.
Again, thanks for all input.
