My mother took the Jeep in the morning for work and came back home at 6 pm. She came home and she told me the Jeep is not starting. I went and checked it out myself and all the car does is click and then a little code saying no bus or bu5. Either one. Before deciding on buying a starter does anyone know what my problem might be. I checked the cars terminals and they had good connections. I also tried replacing the battery with a different one from my plymouth and still same problem so it's not the battery. Oh and when you try to start it the first time and you hear a click, after the click all the gauges die out. If anybody can help me out or tell me what to try to do to make it start I would greatly appreciated.

 

Check the write up section for xj and the "fixing no bus" write up. Maybe it helps i've never had that prob before GL

 

Could be the neutral safety switch if its an automatic, try putting it in neutral and starting it. I've been through 3 neutral safety switches...major design flaw

 

do all electrial items cut off ,like do the head lights still work radio ect

 

All the other stuff still work. jeep98cherokee I will try starting in neutral. Feel really angry now because we bought the car for 4 thousand. Yes overpriced but we were desperate and now it doesn't want to start. What bad luck. Funny how our 92 plymouth acclaim is running perfectly fine even better than our jeep. No hate

 

*A "no bus" message on the dash along with your described symptoms is almost assuredly not a starter problem. Save your money.

*Something on the computer "bus" is inhibiting juice from getting to the starter. Check to see if you have 12 volts at the starter itself with the key in the ON position. I'm guessing you won't have it. And if you don't, that confirms that your starter is fine.

*If it is the neutral safety switch, normally you won't even get a "click", you'll get nothing. Unless that clicking is the starter relay.

*Start with freshening grounds. Did you actually "clean" the battery terminals?
----------------------------------------------------
Grounds can be the root cause of many electrical gremlins. Refreshing grounds is NEVER a bad idea!

You can't just check or look at these grounds. You must remove, scrape, clean until shiny the cable/wire ends and whatever they bolt to. The one on the back corner of the head, and where it attaches to the firewall. Scrape the paint from the firewall. Best to replace that woven cable with a #4 or #2 gauge cable. You can attach the one end to the intake manifold if you would like.

Next go over to the engine dipstick tube stud. Remove the nut and clean the wire ends and scrape the block until shiny at the stud. Reattach tightly.

If you are so inclined, add at least a #6 cable from the negative terminal of your battery to one of the bolts on your radiator support. Scrape the paint off first.

 

I agree check the grounds first, i had a similar problem the other day, turns out the battery had gone bad my lights and radio still worked, but the lights were dim, also you said you put another battery in?? MAKE SURE THE BATTERY YOU PUT IN HAS AT LEAST 500 cold cranking amps!! if not you will have problems starting.
Best Of Luck Man!

 

Thanks for that. I woke up at 6 am today and I decided to try the hammer and starter trick and the bus code magically disappeared and the car started to make more than 1 click. I will try what you said above and see if it'll work. I'll keep ya updated lol

 

Ya now try to switch the battery for a different one, or try to jump start her then reset the computer.

 

Lol fixed the problem!! I replaced the oem battery terminals with new ones a while ago and I guess the red wire going to the starter was out. How dumb of me not to see it. Thanks for all the help guys.
