Question Idle Control Valve not getting power
I've been trying to determine cause for the very hard to start situation of my1992 300 E.

I just tested the ICV and when I supply 12 volts to it I hear it working.

Problem is that when I crank starter I do not getting any voltage going to ICV connector.

I have tested all sensor in the head and they are within ohm specs for a cold engine.

When I test connector wires for ICV connector with ohm meter I get 157K ohms.

So what next? Do I have a broken wire somewhere?
