Slight Front End Damage / Now will not turn over
1990 190E 2.6 149K
Recently, the front of my 190 got up close and personal with the trailer hitch on a monster F350. There was no jarring impact, just a quick stab and the show was over. The grille, AC coil, and radiator were cleanly puntured. The engine stopped running on its own and, at the time, I did not think anything of it. I have replaced the coil and radiator but now I'm being forced to think about why it instantly stopped running by itself. When the key is turned to position 1, everything happens as usual. All of the electrical accessories work and I think I can hear the faint sound of the fuel pump for a moment or two. When turned to the starting position I get nothing. No clicking....not even a cough or sneeze. Is there some sort of safety mechanism that needs to be reset after an event like this? I have checked out everything I know to check and it all seems to be in fine shape, just like it was before the unfortunate event. Any ideas on where I should go from here? Thanks, Sam |

Check your OVPR under the windshield plastic rain shield. Silver aluminum can.....
Has two fuses on top under a clear plastic flip top cover. Earlier ones had ONE fuse. Check also the date on it's side...older than 5 years ,buy a new one. .

Even if the OVP were out, engine should start and run. I would check carefully the vicinity of damage for electrical harness problems as a first choice. Also, look for damage at front of engine, if puncture proceeded far enough.

Is there a crankshaft position sensor located down by the crankshaft pulley? If so it might have been damaged or knocked out of position in the accident.

Thanks for the ideas.
I'm beginning to think it may be the Neutral Safety Switch. I will check the OVP Relay and the crank angle sensor just to be thourough, though. But, even if both the relay and sensor have failed, it would still turn over I think. Right now, it won't even do that. The reason I'm thinking NSS is that my wife was pretty scared when the accident occured and I'm slowly recalling a mental recording of her really slamming the shifter into Park. It's possible that this could have been the last straw for the NSS. They are fairly infamous for failing at the most perfect moment. I will check it out by bypassing the NSS. If that's all it is, I'll be a happy camper. Thanks, Sam |

It's the NSS.
I can get the car to start by holding the key in "start" while pulling back a bit on the shifter. It fires off just betweet P and R before reverse actually engages. It's a cheap part to replace. Finally a stroke of good luck!
Thanks for the replies. Sam |

It could be a bad NSS but it may be that the NSS is out of adjustment from the engine and transmission assembly moving forward slightly in the accident. Check your shift lever position carefully to see if the lever truly lines up with the detents in the shift gate---my guess is that it is off just a bit (not fully in Park with the lever pushed all the way forward). It is possible that merely adjusting the shift linkage will get the NSS operating properly. Mark
