Long crank time on 2015 JK

Is it normal for the 2015 JK with the 3.6L to take a while to catch when first starting? I have noticed that it doesn't matter whether she's hot or cold, it takes what seems forever for the engine to start. Do I need to give it a little gas beforehand? Seems weird in a fuel injected engine...

Re: Long crank time on 2015 JK

You should only need to briefly "tap" the key to the start position, and quickly release. The computer will actually start the engine for you, running the starter for only as long as needed.

You should not need to do anything, including pressing on the gas pedal. Again, the computer will handle taking care of anything that needs to be done to successfully start the engine.


I assume, it always is successful in starting the engine. That you only feel it is taking too long. I would bring it in for service, and have them check for any error codes being stored that might indicate if the computer is finding a problem while it is trying to start the engine.

'tapping' the gas in modern vehicles does nothing.Like Walt said, the car will start itself. Its not the old days where you have to crack it till it fires. Its all done by itself on all modern vehicles.

1st you need to visit the dealer . Now to check the iac crack the throttle slightly an bump the starter .
If the iac is slow this should start you now . Budd

Re: Long crank time on 2015 JK

I only use a couple brands of gas. I found that getting gas at Get Go, BP, Exxon and a few others made every vehicle I have owned crank longer. I use Shell, Sunoco and Marathon now and I no longer have the long crank issues. It takes a few fill ups to get rid of all of the bad gas out of your tank, but you can notice a difference almost right away.

Re: Long crank time on 2015 JK

brand of fuel should make no difference in crank times. There is something else wrong here

Contraire Mon Fraire...gas makes a huge difference. All my vehicles had longer crank times with the bad gas I mentioned above and none have the issue now.

It does not matter what gas I run in my Jeep or a co worker with his new Jeep. If what you say is true, all cars/Jeeps would do it.

Im sticking with you have an issue

All vehicles do run crappy with crappy gas...case in point...."Get Go" brand gas from a local grocery store. No matter who I have talked to, they have longer crank times when the weather gets cooler/colder. My vehicles would sit there crankin' when I ran that gas. Filled up twice with a better brand and no problems. Each vehicle I owned had the same problem.

Re: Long crank time on 2015 JK

Where do you think get go gets their gas from? They dont have their own refineries.

Yup, they buy it from the same suppliers who supply all the other gas stations.

You may be running Sunoco one week, Citgo or BP another week.

Like I said before, its something else not the gas

I bought gas at the Glassmere station one day because I was low on gas. There are a lot of hills around where I live and flooring my vehicle it could not keep up with traffic. Complete crap gas. You are just regurgitating an old wive's tale about gas staions and refineries. It ain't true.

What isn't true? That a little stop n shop store don't have their own refinery? Are you kidding me? What I am saying is 100% correct,. Water in your gas may do that but that is because the station has a defective water separator, its not because of the gas.
