Just cleaned NSS, engine won't start in neutral... help?

As the title states, I just cleaned out my NSS and now the engine won't start in neutral... is it supposed to be able to start in neutral? I think it is....

the most difficult part about the whole process is the wire loom... otherwise it's an easy job.

edit: It starts in park and now my reverse lights come on flawlessly... I almost forgot what they looked like since I haven't seen them light up in so long. My only problem (so far, it's only been 5 minutes since I've been done) is the no start in neutral....

any help and/or tips are appreciated!

theres a good reason why it doesnt start in neutral its not suppose to lol thats why its an NSS (neutral saftey switch) it makes it so that the jeep knows when its in park so the jeep will start any other gear it wont start that way you dont accidently start it in gear. kinda like not being able to start a manual without the clutch in.

That's the most uninformed answer I've ever heard. Have you ever tried to start your XJ in Neutral?...it should start. Have you ever owned a car with a stick that will start without the clutch pedal pushed down? That clutch switch is a relatively recent thing, I think it's only been common for 10 or 15 years now...my XJ will crank without the clutch pedal depressed (in gear or not), heck VW's up until 1999 will too.

You should be able to start the vehicle in Park or Neutral, but not in any other gear. That is the function of the NSS. Re-check your work and make sure the switch is installed and hooked up properly...I don't think I've ever changed one on an AW4 personally. However, if this was me, I'd just say screw it and start the thing in Park every time...that's just cause I'm lazy though.

That's what I thought... I just cleaned it out, but I should've checked for the proper cleaning stuff before I decided to go hardcore on the uninstall... did a half***** job on the cleaning part... another day I'll most likely have to take it apart again, I just wanted the reverse lights to work since inspection month is starting tomorrow.

It's funny that the owner's manual states nothing about being able to start it in neutral, only park.

Anyway, thanks again.

Here is basic definition of the NSS:

Switch that prevents the starter from operating in any transmission range except park or neutral.

Loosen the set bolt on eth housing and rotate the NSS a tad either up ir down and see if you can find the sweet spot.

After cleaning mine, it started in P or N. but the rev lights didn't work. I had to fiddle with the adjustment on the housing to finally get everything to work.

I'll def. do that after it's sat and cooled off. Real crappy thing is being right next to the exhaust! Thanks for the info!

I have yet to see a properly functioning car with an automatic trans that doesn't start in neutral. The NSS makes sure that the engine is not connected to the drive wheels through the transmission when the key is turned to the START position (hence, the engine sees a neutral position, turning nothing but its own crankshaft). That means it's safe to start in P or N, not anywhere else. I don't know if XJ's work exactly this way, but if you take a newer WJ and look at the transmission datastream on a good scan tool, there are only two indicators for the shifter position...IIRC one looks like "P-N---" and the other is "-R-D321", they change depending on where the shifter is placed, but it's always one of those two, never gets more specific than that.

My NSS was doing the exact same thing after replacing it. Like already mentioned, I just loosened the top bolt and turned it as far as I could then tightened the bolt down

Now everything works! Sweet!
