My wife’s 94 E320 (155000 KM) failed to start after she returned to it from shopping. Started and drove fine to the store. The battery is fine, lights strong all dash lights come on fine but it does not crank. I tried the 3 things noted in the archives:

· Lock and unlock the doors from both sides in case it is a security system switch.
· Put it in neutral to try and start.
· Jiggle the ignition switch and try it a number of times.

All to no effect. I did however notice a soft buzzing (about 1/3 the volume of the “key in & door open” buzzer) coming from under the dash approximately near the head light switch, when the ignition is turned to the on position.

I towed it home with my Jeep this evening, so it’s now in the garage. Any ideas on the next course of action?

Thanks,

John
