hey97 im back again....do you have the read outs for the for the rear crank sensor? I will tell you how to tech the sensor if you wish....all you need is a vom and a little patience.

a special thank you to crhenkel dude!!!!!! you located the tdc sensor for me and I thank you...I also have a 190e that will not start and guess what!!!! if found a broken wire on the sensor lets see if this is the problem....thanks for the pics

I think the spec is something like 600 ohms to 1200 ohms is acceptable. Well the sensor falls like 800 or something, well within spec. I dot know actual number but it was within factory spec

thats the spec that you need .....now check the opposite side at the ignition control unit and see what its reading ....use your vom to 20 volts scale and see what that is reading ...turn the key on to volt the system ...it should be around 11.5
one more check is to see if the insulation on the sensor is still good on the ohm scale read the middle of the sensor plug to ground .....if it stays at 1 your good...if it reads you need to replace.....make sure you check all of your electrical connections on everything
