When the NSS is dead, everything turns on (except the reverse lights) it just won't turn over. Irrelevant anyway. Grab a starter from your local JY and swap it out.

yea that was everyones initial thoughts the starter but, if it were the starter it would not start at 2 pm then not start at 4 pm ..then start again at 11 am the next day...thats y its so weird....

 

Have you taken off the wires on the starter and cleaned them? And the battery terminals?

...

 

Bottom line is if it's clicking and not cranking it's an ignition or electrical issue. Start looking for loose wires, dirty connections, etc.

i replaced the terminals....but have not cleaned wires connected to the starter...i was thinking of just replacing them..

 

if the problem is electrical, what do you suggest...?

 

It's a nightmare. I had some issues with mine...it's really just the tedious matter of following wires, checking connections and fuses, cleaning grounds and connections. Get some PB blaster, steel wool, and a rag start looking! Fuses are easiest so start there. Let us know what you find.

how do you kno what fuse is bad? the squigly line

 

Yeah you just have to pull them and look. It's kind of U shaped when you look through it. If it's burned through its bad. It obvious when you see one. Start with the fuse box under the hood.

cool ill check it tomorrow...thanks...ill get back tomorrow

 

Bet it's your CPS (crankshaft position sensor). Use "search" feature on this site and you'll find that your symptoms usually are caused with a bad CPS and need to replace it

 

That's a good possibility...but they aren't cheap and it's not a part you should get at a JY and it's a PITA to put in. Check your connections...start at the starter, and your fuses.

i'v got news for you my starter went out replaced it ran perfect for obout 3 weeks started not starting properly just like what you are saying one time no start climbed under removed starter trid it and gess what no motor sound. removed walked to nericed auto parts exchanged with new installed 2 yrs. later no problem starts everytime.

 

Im willing to put money on the CPS aswell. I had to replace mines not that long ago. No they are not cheap and no they are not easy to replace. Easiest way to replace is to drop the tranny slightly if possible. Check your CPS and the wire going to it. It could also jsut be dirty. Ive heard of people cleaning it off with a toothbrush and soapy water and it works again. Mine just died so I got a new one. Goodluck though.

BTW: An old trick to see if its a starter problem. Go undernether the jeep and tap the starter slightly with a wrench and see if it starts afterwards. If your starter is starting to go bad but isnt completely bad it might crank over.
