2012 won't start, then it does
Hey guys, hoping you can help me out. My wife's KK has a few issues I need to fix. I was planning to take it to the dealer under the extended warranty I bought with the Jeep, but I found out that the 4 year/60K warranty they sold me expired when the Jeep hit 60K not 60K from the mileage when I bought it (25K). My fault for not reading the details better but now I am in a jam as this is our only vehicle at the moment.

The most pressing issue is that the Jeep just started having a starting issue. If it has been sitting for a while it won't start first try. A second later it fires right up, but I need to deal with this before it gets worse. The battery is only a couple years old, it's trying to crank so don't think it's the starter. Fuel pump maybe?

I didn't see anything on a search but hopefully someone has dealt with this before. I really can't afford to throw money at this thing needlessly right now.

Fuel pressure is what I was thinking too. If a fuel pump is on the way out it can take longer to get up to pressure.
Also assuming you don't smell gas at all, so it's not a leak.

Something else to do that's easy and relatively inexpensive is to change your spark plugs and air filter.

Thanks lfhoward, I changed the spark plugs around 45K, that was 20K ago at this point so probably should be checked. The air filter gets changed with every oil change. I have never noticed a gas smell at all. I may just have to break down and try to swap the pump. I wish there was some more troubleshooting to be done before I just start swapping things out. I am a little out of my element on newer vehicles. The newest thing I ever drove was my 2000 Wrangler, and it really didn't have the technology of most cars from that time.

If you have a fuel pressure gauge that you can get a read from, that would confirm or eliminate the pump as an issue. I have had some problems starting mine as well lately (maybe once a month) where it will crank and not catch. Then if I try it a second or third time it works. Sounds familiar. I haven’t tried to track this issue down on my Jeep yet, since there are no other symptoms and it’s pretty rare. At some point it will happen all the time and be really annoying and then I’ll probably have it checked. Lol. Right now if I brought it to a mechanic it would most likely start up fine.

Can't say for sure what yours is, but a new fuel pump fixed my daughter's 08 with the same symptoms.

The time now is 06:24 PM.
