Starter won't engage when cold

Ok guys I have read many threads on hard starts in cold weather but mine seems to be different.

The last couple days have gotten into the low 30's at night and when I go to start the Jeep in the morning it wont even crank. I have to turn the key on and off multiple times to get the starter to engage. After a few times you can hear the starter try to engage and then a couple more times it will engage and it starts right up.

I have checked the wiring and everything seems fine. It has only done it since the weather has gotten cold so I believe that has to be related.

Thank you for your thoughts!

Pull the starter off and inspect it. Get it bench tested that way you can see what it is doing. Bring it in first thing in the AM when it will be cold.

^Do that, put it in the fridge if its not cold enough. I've had a starter not kick the gear out before and just spin. Hopefully checking it will determine the problem.

Yeah, I would check the battery as well as the starter. Again, make sure both are cold-tested. My 4.2 starter would occasionally freeze up, but it was nothing a tap or two from a hammer would not solve. But man, it sucked getting under there int he cold to beat on the thing.

I had the battery checked already just in case I was good to go there. I will pull the starter and get it bench tested. Would it be possible for water to get into the starter and freeze? I have been through my fair share of deep water holes this year..lol

Yes it is possible for water to get in there and freeze. I have experienced this before. But first ensure your cables and connections are good. If so, try rapping the starter with a dead blow hammer. If she starts up, replace the starter. If this works, the brushes are likely worn out and the "jostling" from the hammer will allow good enough temporary contact for the starter to work.

Sounds like a classic battery problem so check both the starter and battery
