1993 Other Mercedes Benz Models Car will not start

It happend to my car a few months ago, change crank position sensor, and cam position sensor not helped, I changed the metal relay behind battery (covered with a pastic cover too.) With 9 legs and it started right away, hope this helps.

Hey Same user diffrent name (the one whom posted the question), I was ignorant of the last reply that I had on this question. So today I went to the MB dealership and talked to a couple of the techs they informed me of a common problem with the W124 cars, the voltage overload protection relay located near the fire wall and on the computer has "problems" that can cause your car not to start. So I brought the part 116.00 $ and a big dent to my wallet (college student) and replaced it in the parking lot. The car started right up like the previous post person said. So I went to a store, and tried to cut it off, but it would not cut off so I put the car in drive and switched the ignition off it finally cut off and has been doing fine ever since so thanks to everybody who attempted helping me solve my problem.
