i dont understand how the Neutral saftey switch works? if the NSS wont work then the car wont start on P or N? i've been having to put my car on N to start it and it would sometimes work on P.. what is the NSS there for? My 82 240D started making a really bad noise when i was doing highway speeds and when the car came to a stop (almost sounded like it needed an excorsism) smoke was emitting from the bottom of the transmission, and around the starter/ left side of transmission.. oil pressure was good, temp was good so i was confused.. turns on out the start motor spines was grinding against the flywheel notches. I took out the starter and i noticed the notches where pretty much cut up and noticed a bit of metal shavings in the whole where the starter goes.. when testing the old starter while it was still in car, it would just click.. hopefully its just the starter and the NSS which im replacing when the parts get here.. i'm going to check ground connections that u showed.. is there anything else that would make the car not start or is it just Battery, NSS and starter that is neccessary for the 240D to start? thanks edit: i tuned up the car prior to this annoying issue
Neutral safety switch. fuel ( clogged up filters ) bad starter are pretty much the only things i can think of right now, it's 3am here. The neutral safety switch, if your car is automatic, it makes the car only be able to be started in either P or N position on the selector. If the car is not starting, and the battery is good and the starter is good. Then wiggle the gear selector around a little bit when in the P and N positions when you turn the key to start the engine ( keep wiggling as you turn the key )
Any suggestions for no crank no start but only happens sometimes then a few days later start again as if nothing happened? The dash lights are on but when I go to turn the key there is NOTHING! I already changed out the glow plug relay fuse thinking that was the issue. This started happening after a local shop changed my oil.
Hi there. 1st. If automatic, wiggle the shifter/selecter while in park and neutral positions, if the car starts. You have a bad neutral safety switch. You can bypass this, but that's for another video. If 1st was not successful. 2nd I would take a look at the electrical connection on the starter motor itself. It may have had a bit of oil drip onto it, or it may be a coincidence and moisture over time from rain and moisture have made a bit of corrosion start on the contacts/posts/pins. You could put the car into neutral and have a friend inside of the car while you put +12v to the starter motor +12v starter bolt/screw and if it starts, the starter motor is good and the problem lies elsewhere.

@@qwertyui90qwertyui90 Thanks so much. I will try the 2nd suggestion tomorrow and let you know any findings!
@@boxchevyhill I'll make a video where i show what i mean with a w123 300D starter motor out of the engine bay so it's easier to see :)
@@qwertyui90qwertyui90 sounds good! thanks!
Hey, I figured out my problem. Look here > th-cam.com/video/EpC_h-IYQG0/w-d-xo.html
