Is the engine wiring harness original? I pretty sure this model has the brittle wiring insulation problem. Some MB mechanics will not move forward with driveability diagnostics unless the engine wiring harness is replaced. This is because of the spurious shorts that occur when the insulation flakes off. Take a peek under the wire wrap to look at the condition of the insulation. You may be shocked.

He has an S-Class and it has been my understanding that the S-Class did not have this "wiring" issue. ??

i dont know if the harness has been changed but i highly doubt it has been.
its a 93 500sel w140 i belive some people still consider the 92 and 93 ans s-class, i dont know if the eletrical is different from the actual 94-99 s-class???

for the turning off problem:
ok so i have been real busy lately with my new job (12 hour shifts). but i droped off the car with my mechanic and its been there for about 3 weeks now, and i went in yesterday to check on it and he said, that the problem has to do with fire??? and he ran diagonstic and and two things came up which were the main crank sensor and the distribuator's sensor's (but he said they have another name) which he pointed out were at the top of the distributors, they're circle shaped, and they look like metal. now he said he not sure exactly which one it could be but more likely he thinks its the crank sensor. but says if its the distribuator senors its not going to be both its only going to be onw since theres two.

so i dorve out to the delaership and got a print out of the crank sesnor to confirm with my mechanic the correct part. but i couldnt find on the delaers computer the distribuator sensor, instead they printed the cam sensor ( i dont know if thats the part???). im going to confirm the parts with my mechanic tommarow so that i can order???

would a crank senor cause the shutting off of the car with that exhaust popping noise????

or do these suggestions that my mechanic gave me even sound about right for the problem???

please i really need your guy's help because even though hes my mechanic i still need and want your guy's suggestions and expereince???

thanks

Hello,
There is nothing called a Distributor sensor, there is a Cam position sensor and the Cam adjuster. The Cam adjuster sits in front of the intake cam and is round, that is right next to the distributor because the distributor is driven off the exhaust cam. There is also a Cam position sensor, that is located on the side of the head next to the intake cam. (just to the right of the Cam adjuster) There is the Crank shaft position sensor as well, that is located on the engine block in the rear, usually around the starter. Your mechanic stating it has to do with Fire is correct, he actually means spark or timing, the firing of the engine. The Cam sensor and Crank sensor notify the computer of the position and adjust the timing according to the information recieved. Replacing these is likely a good place to start. Have you checked your plug wires, plugs, and coils? Check out our website at www.mbca.org/northtexas click on technical and then engine technical. Review the engine controls, there you will see on the 119 engine where all the sensors are located.

yeah he meant cam sensor... sorry
i took the print outs from the delaer to my mechanica and he pointd out the crank postion sensor which he would recommend changing out, so i did a little bit of reserch and it sounds some what similar but the difference is that most people that need this changed out have problems with there cars turning off when there hot (after driving for a while), where to compared to me where mine turns off after the car is only on (in park or driving) for 10-15 minutes. the previous owner had the problem of it turning off after drivng a long while then he would have to wait half an hour and then it would start, he sadi he fixed the by changing the distribuator???

i got a price from the delaer they said $202 for the crank postion sensor 93 500sel. i tried checking online and the i only found cam sensor for $140, but not any crank sensor. do youn know of any place that i can find a better price than the delaer $200--???

thanks in advance

If there are not any parts listed on the catalog at Fastlane then give them a call, they will help you out. Also check performance products. It takes awhile to get the parts, but they are genuine MB parts at a good price. The dealership is expensive unless you get your MBCA discount.
I would fix your timing issue first and get the engine running, then after that if it dies after it is warmed up, you have another problem. The CAM and Crank position sensor likely has nothing to do with temprature, but keep in mind the engine fuel mixture and idle are adjusted according to temprature, the sensors that feed this information to the computer would be at fault.
