The Mud Pit > Wrenching
Another XJ down, not cranking stranded at work
BlacXJeep:
Ok so I got out at midnight last night, to find Black Betty dead. Shes got power, but tried jumping her anyways. She doesn't turn over whatsoever, and no click. I can hear the fuel pump turn on also, so I think I can rule that out. I also tried hitting the alternator and starter with a hammer, and nothing. So I'm thinking the diagnosis is either Neutral Safety switch or the starter, maybe CPS???. Tried wiggling the wires to the starter and the harnessing for the battery. I also unplugged the NSS connector in the engine compartment, no dice....
So if anyone has any ideas, or has a few hours this weekend to come out and try to figure this out it would be much appreciated. I'll buy you some beer or something. I haven't renewed my AAA so I can't get it towed unless I want to pay $90. Its in Mystic right off Jerry Brown rd.
Any ideas are welcome.
PaulW:
did you try starting it in neutral?? how about jumping the wires at the starter?
calvynandhobbs:
If it's the NSS you can normally start it in neutral or just jiggle the handle around a bunch and try it. Mine was doing that for the last year. Every now and then when I'd go to start it there would be absolutely nothing. I would just give the gear selector a couple slaps and it would start right up. I actually have a spare NSS at the house that I will sell sometime in the future. My plan was in rebuild it before taking the one out of my XJ so that my XJ wouldn't be down at all.

From my experience with the CPS, it will not allow the engine to send a spark, but shouldn't stop the engine from turning over, so I wouldn't start with the CPS. Also my experience with starters is that they wear out over time, turn over slower and slower or intermitantly crank over, so my keyboarad diagnosis is not to focus on the starter. It could be the starter soleniod, but you usually will hear a click with them.
With that being said, I would go with the nuetral safety switch. Like Paul said, try it in nuetral. It's a $230 part new, and even with 10% military discount, it's still over $200 :(. If it turns out to be the nuetral safety switch, you might want to try a few bone yards that have a 90 day warranty.
Does anyone know a way of bypassing the switch?????
PaulW:
it appears to have a starter motor relay. try swapping it with another relay 1st.
there doesn't seem to be any way to bypass the switch, it looks like the pcm takes the signal from the neutral safty. if you have to just run some wire to the starter and put the solenoid on a push button starter.
