2001 Cherokee Sport- new battery wont start

hey JeepFreaks...
this morning my 01 Cherokee wouldnt start...you could hear the very last of the battery draining and then all i heard was a constant clicking as i was trying to start the ole truck. ok, i figured battery was finally dead. so, i rolled out bought a new Interstate battery, hooked her up, and now when i try to start up the truck- nothing. no turning over, not even the clicking i was hearing before. lights on the dash light up but that is it.

please someone tell me what need to do. i am pretty handy and do most work on my jeeps (two wranglers, one cherokee) but i truly have no idea where to start with this cherokee not firing up.

any help is greatly appreciated!!

Hmm. Bad starter possibly? Bad ground?

I say check the new battery with a voltmeter, but you said your interiors come on.
Is the new battery a stock size? I have seen upgraded batteries (taller) touch the posts on the hood whenever it is closed.

And I know it seems pretty basic, but clean the battery cables with a wire brush. It may help.

thanks. battery fits fine...the cables had some minor corrosion buildup from the previous battery but nothing crazy. think it could be the starter?

Loose, corroded, or damaged battery cables or ground wires may cause or contribute to the problem. Begin with basic trouble shooting of the start and charge systems. Remove, clean, and firmly reconnect all the wires and cables to the battery, starter, and alternator. Look for corroded or damaged cables and replace as needed. Do the same for the grounding wires from the battery and engine to the Cherokee's frame/body.

Just follow the actual wires from the battery, alternator, and starter. Check the ground wire that is on the back of the engine and goes to the firewall.

No wiring diagram needed to get started. I would start your focus on both battery cables on both ends. Use a commercial battery post cleaner or some steel wool, sandpaper, etc. and work those connections over until shiny. You can't tell by looking at them. And don't forget grounds.

Basic thing but you're sure the new Interstate battery you bought is fully charged?

If the engine was "cranking/turning over" before you put the battery in, this really sounds like a connection of possibly a ground issue.

If above checks out, I would get a multimeter and put it directly on the starter itself. With the key in the ON position, you should have approx. the same voltage as you have at the battery. If you don't, you need to start working your way back into the engine bay to find out why.

yeah the interstate battery was fully charged. bought brand new at tire place up the street. i cleaned the battery cables with baking soda/water mixture and used a brush.

i also did a check of the wires but i have to be honest....i am lost under the hood of a cherokee. wrangler is a little easier to navigate around under the hood. anyway, i checked wires etc and didnt see anything that caught my eye but that aint sayin much. the ground wire is fine- still connected to the fire wall and the connection the negative wire is secure.

i turned the key but still nothing- dash lights etc come on but no clicking pr anything from the engine. dammit.

looks i will be gettin this thing towed to the gas station down the road. ugh. i really appreciate the help everyone.

Been there... You could try a different relay to see if it makes a difference.

ok, so get this: i get home after runnin around in my wrangler for a while. i, again, try to start the Cherokee, with no luck. there was some weird electrical stuff going on after i turned the key all the way to start the engine....weird meaning- the chime was continuing to ring, the hazard lights were flashing, the lights that illuminate the dash were flashing on and off, and the stereo clock was flashing off and on. this happened before as well but i paid no mind. anyway the only way earlier in the day to make the "electrical" orchestra go away was to take the negative battery cable off the battery. but this time, i simply pushed the "unlock" button on the remote of my alarm keychain that came with the cherokee and the electrical storm stopped. then i turned the key to start up the engine....and VOILA. it started up. ok, ummm, WTF??? i was thrown for a loop.....and still am. i have no idea what the hell happened.

if anyone out there thinks they can explain what happened, please feel free. i am still going to get the truck a once over at my shop i always take it to, but i can not for the life of me figure this one out.

but at least my rig is runnin....

only thing i can figure is that it has something to do with the automatic lock and unlock system....there has got to be a bug or somethin in the electrical system. what i will most likely do is just remove the fuse for the auto lock function. i wont be able to use my cherokee keychain anymore to lock her up and unlock her but what else can i do.

Yeah I guess you can do that. You should just check all of the fuses though.
