Angry Is it my starter?

So last night, my 98 Jeep TJ 4.0 ran fine. On my way back from school the check gauges light came on. The oil pressure gauge just went to zero. I pulled over, checked my oil, and it was fine. Didn't think anything of it, maybe just a bad wire somewhere that wouldn't affect anything. This morning on my way to class, it ran terribly! out of nowhere it just died as I was coming to a stop. I tried to start it again and just *click*, I had a pretty strong feeling it was my starter (as I bang my head against my steering wheel because I just replaced my fuel pump 2 weeks ago ) So i try over and over again, and just a single click every time I turn the key. My gut says starter just because its cheaper than an alternator

It sounds like you have a dead battery. They can cause all sorts of weird issues in our Jeeps. Take it and have it tested as an auto parts store. They'll be able to test it under load which is more effective than just checking it for voltage. You can also have the alternator tested. If it stopped charging it would have killed the battery and caused you to stall out like you described. The starter wouldn't cause the Jeep to run poorly so I don't think that is your issue.

Good Luck!

Going off what ryan said...I would actually assume alternator over battery. Your battery may have been good, but your alternator wasnt charging it.

Technically speaking, once your jeep is running, you should be able to remove your battery and the alternator should be able to put out enough to keep it running. In your case, the alternator could be bad because it couldnt keep up...your jeep then used the battery power until it finally died. Now when you try to start it, your battery is dead and cant turn it over.

You can take it down to the auto parts store like suggested, and get all 3 parts tested though and that should help narrow your search as well.

Was it a single click, or multiple clicks?

Multiple clicks tend to be a dead battery...a single one can be starter.

Try giving the starter a few taps with something, and try turning it over again. Most of the time, if your starter is bad and you tap it...you can get it to work again. I have limped around town a few days this way until I had time to replace it.

Its a single click, I banged the starter but to no avail. I'm considering going up to the store right now and buying a starter, but I worker in 2 and a half hours, is it something that I can replace in an hour or so?

its worth noting that the tapping of the starter is actually tapping the solenoid, which happens to be part of the starter on jeeps.

Regardless, the starter motor wouldn't cause the gauge issues or the jeep to run poorly.

I agree with the previous poster who said it could be your alternator, and would also suggest that you check your grounds as well, and see if one is disconnected or dirty.

There is a chance that a super dead battery u may not even get the multiple clicks. A starter is relatively easy to replace if that is what u do need

like check all the ground of the whole jeep?! lol
also, how can i test the alternator if i cant get the jeep started?
I took the starter up to advanced auto and got it tested it's fine.
my next question would be: my dad thinks that its my OPDA, now that makes a little sense because my oil pressure gauge dropped the day before my jeep broke down. the check guges light came on, but i thought it was just a bad sensor somewhere and nothing to worry about. Does the 98 have a safety switch that would keep the jeep from starting if it has no oil pressure? If not, how could I check my oil pressure so I can get my dad off my ass. I don't think its the alternator because my battery still has a full charge (12.5 when off) even after the jeep died, and if I'm not just pulling this next fact out of my ass, if the alternator is bad, the jeep would run off the battery and drain the battery before it stalled right?

Last statement about alternator and battery is true. Happens a lot. People get a jump or charge battery is good till it runs out of juice. If dad is right. That could be expensive. But no oil pressure and no issues = sender. No oil pressure and no oil pressure = $$$. No safety shutdown I know of. Hope it's not it just siding with dad a bit.

Edit. Check alternator by taking it to auto zone or o Reilly's. They have a machine. Good luck

Alright everyone, I bought a volt meter, battery was fine, i took the alternator off and ran it up to autozone, it was fine, I replaced my starter relay, it was fine. I gave up and just got it towed to the shop, I'll let you guys know what it was as soon as I find out!

Wow. How many miles? I was considering installing a Melling high volume oil pump at the same time I do my rear main seal and oil pan gasket. This might help me make my decision.
