Hey guys. I recently bought 2002 grand cherokee laredo 4.0. It would sometimes start in park most of the times would not. It would start in neutral everytime. After reading some posts on this forum i went and replaced neutral safety switch. After replacing nss it did the same thing. I tought maybe i got bad nss went back and repalced it new one does the same thing. Only sometimes will start in P it starts in N everytime. Any ideas or opinions would be appreciated. Thanks

Did you adjust it correctly? Do the reverse light work? If not put it in reverse key on engine off and adjust the nss until the reverse light come on. Give that a try. BTW, This is the section for the XJ not the GC. But it should be the same to adjust the nss.

^yep.

Just did mine this past week. Here's the info I used:

https://www.cherokeeforum.com/f51/cf...sh-how-182998/

"Go back below to your N.S.S. and very lightly install that mounting bolt. Then very gently install the mounting nut onto the threaded collar/shaft. I say gently because there is some more guess work here. You will notice the hole in the housing that the mounting bolt goes through is elongated to allow for adjustment of the N.S.S. I put mine kind of in the center and then lightly tightened the mounting bolt down. Get the mounting nut on the shaft just a tiny tad over finger tight. Go in your Jeep and try shifting the transmission. If your shifter is suddenly more difficult to shift, then either the mounting bolt or the mounting nut is too tight and causing the N.S.S. to bind on that shaft which also (gasp) goes through the other side to your shift cable. At this point it is a game of Up-And-Down. Get everything nicely tightened and adjusted until the shifter is smooth like it was before. Then turn your key to 'ON' (not start) and put it in Reverse. If your Reverse lights work, one check. Put the Jeep in Park and try to start. If it starts no problem, another check. Turn it off, go in Neutral, and try to start. If it once again starts fine, then you are good to go and you have everything good to go! Make sure your mounting bolt is snug (doesn't need to be crazy) and your mounting nut hand tight. Then take your flat-head screwdriver and bend up the tabs on that lock washer to secure the mounting nut in place and prevent it from spinning."

Thanks for your replies. 2002 uses different style NSS , older models used adjustable one. My 02 uses this one http://www.oreillyauto.com/site/c/de...+safety+switch
Funny thing is reverse light does work.

Yeah, That is completely different from the XJ. Try posting your problem in the GC section. Hopefully someone there can help you with your situation. Good Luck!

Right off I'd say you need to find out how the connection is made from the park position to the NSS. Does putting pressure on or jiggleing the shifter in park make any diff?
