W124 M104 3.0-24 starting issues

[Benzsc1]

This issue is still ongoing I thought \I might bump the thread to prompt any new responses....

My next mission is to check all the voltages and resistances specific to the Ignition system and its components.

Failing this its going over to Bill Schraders!!! Or it shall be burnt Just kidding

I've not seen your previous threads on this but have you checked the idle control valve? This is an easy swap and known troublemaker!
