had the same trouble with my 86 2.3-16. When i had the car towed to my Mbenz mechanic's shop, his diagnosis was the car had no spark. This was after I replaced all the level 2 ignition components ie car rotor plugs and coil. I swapped out the ezl module, a 30 second swap, and the car fired right up. The unit i used was from a regular 190e I believe. Car runs fine now
