99 Jeep GC- will not crank

[jeepgirl99]

I have a 99 jeep Grand Cherokee. It started fine earlier. then when I went to crank it later it will not turn over. No power anywhere. when I turn the switch no noise, when i return the switch I hear the flapper move and the gauges move. It is also stuck in Park. any ideas??

I had the CPS replaced about 6mths ago. When it went it would not crank but had power. I am stumped. Any ideas are appreciated.
i plan to replace the brake light switch. cheap and easy fix and it should correct a few problems i am also having with my GC.
Could it be the NSS? is that hard to clean or replace?

Regrets that so many of us missed your post , it happens , but dosen't make it any cooler. Sorry.
i want to make sure I understand . Not turning over and no dash lights , nothing that usually goes on when you turn key to ON position just before you crank starter is working as though a dead battery , am I right ? I'm not certain what you mean by "flapper" , sorry , but the gauges go back to pegged position as normal when key is turned off ? Check all fuses under the hood in the power distribution center to see if any have failed. Make a note of any that did , this helps to diagnose the problem. Of course , change any that are bad and try again . If no success , see if any failed again and note again . We must know which continue to fail. Because there is a current ( electrical power ) flow problem , the shift interlock will not disengage until power allows it to . That is for safety since jeep is not supposed to roll in neutral without power brake assist.
again , sorry for the miss and hope you will keep faith in Jeepz.com . Greg

Yes , that is typical , when the CPS fails , no signal is sent to the PCM ( power train control module ) and does not know the engine is trying to start therefore PCM does not tell fuel injectors and ignition system to give fuel and give spark. Ok , you can bypass a neutral safety switch for test purpose to see if your jeep cranks . Good call . On my XJ , its on the trans , do you have the 4.0 or a 4.7 ? Need to know which trans you have . But it will be o. The trans either way . Must research so to direct you which wires and where they are. Again , regret missing your post as normally we are up to date with new posts and new members .
Oh goodness , BTW , yeah , welcome to Jeepz.com :welcome: hope to be of more assistance and more careful to avoid again missing posts . Sorry .

Thank you so much for getting back to me. I found the problem and it was way obvious. My positive battery cable was bad. I felt soo stupid. I still am having to work out a few kinks in my GC. windows having a mind of their own, my brake pedal hisses constantly and of course the dreaded hood props have failed. I am so sick of carrying around a long stick for a hood prop. I also have a back light that is crazy and the headlights and interior lights only come on when the car is running.. but for all the problems i love my Jeep.. it is just 13 years old.
