2005 Wrangler issue with starting after fill up

Greetings just got a new to me 2005 Wrangler X with 21k miles. Jeep runs great and looks like it was never taken off road.

I am having a strange issue though both times I have stopped to get gas the car will not immediately turn over in fact it does absolutely nothing until I try what seems three or four times, and sit a few minutes then suddenly it will start and everything is back to normal, then I can turn it off and start it right back up etc etc. Wondering If I am setting off some kind of sensor or have some type of vapor lock that would cause this, again its not cranking its doing nothing any similar issues with this model?

not even crank...literally nothing (same as if you tried to start it with clutch not in for example) both times took 3-4 turns with nothing then after sitting for a minute fired up with no issue

that is odd.

Does anyone know if there is some sort of rollover switch that could be getting tripped when he's filling up? (pulling blindly at straws)

I think I figured it out there is an aftermarket ignition kill on it that you have to have a fob in pocket for, and I think the battery in fob was low, anyway the damn mfg. of the thing is now out of business and can't locate a fob for it and only have one left.

I doubt it has anything specifically to do with filling the gas tank. What I would do is remove both battery cable connectors from the battery, thoroughly clean them with a wire brush, I reconnect them & make sure they are tight enough that you can't move the connector once it is secured to the battery post. They can wear & get loose enough that they can be moved even when the bolt is as tight as it can go.

A battery brush with a male & female parts made specifically for batteries is only $3-4 at any auto parts store. And your battery connections may LOOK fine but they may still be corroded internally or loose enough to cause this kind of a problem. Just visually inspecting the battery connections isn't enough, especially when you are having the type of starting problem you are experiencing.

Edit: It seems like you might have a prime suspect with the ignition kill but just in case, I'd clean the battery connections anyway.

Remember that having a different opinion doesn't also require one to be a jerk when expressing it.

When you have a choice, buy American.
