Any dealer that said they won't do the fuel pump recall unless there is a problem are morons. If your fuel pump really did fail, they have to replace the whole fuel system now, not just the pump.
Yep, I got that recall on my '22, crappy Bosch fuel pump that might internally self destruct. It took them a long while to find and source a replacement, I had to wait and pray for about 7 months before they got me in.

Looks like we were all wrong...except for those who said the Z Case fuse. I received it in the mail, plugged it in, started right up with no problem. Went and got more fuel, driving fine.

So, the good part is that I have it scheduled for the recall replacement of the fuel pump anyway. Now I can just drive it there and be done with that. The fuse that blew appears to have caused the whole engine and all electronics to go haywire. Could have been from my wiring, but I've reconnected everything and all is working and running smooth.

I am going over my wiring upgrades and making sure there is no terminal or contact that can end up being grounded and no wire being pulled too tightly. Some of it was kinda crammed in as the diesel doesn't give you a lot of free space to add anything in there around the battery.

Had enough fuel. Fuel pump is still working fine. Ending well.

Thanks to all who at least brought up the what-ifs without condescending remarks, which fortunately I can blow off here as much as all other online forums where pride and ego lead people to want to be rude and mean. Every playground has that.

LOVE IT! How fitting in with the original theme.

Great! Dodged a bullet. Do, please, try to keep more fuel in it - even those of us with gassers sometimes get a bit, well.......... we should do better (don't tell my wife I've gotten a bit below 1/4 on my gas Jeep! She'll really give it to me)

Being a diesel - you've literally checked all of the wiring that a few of them seem to have issue with?
Instead of rehashing the whole thread, just a suggestion to be sure to have it settled in your mind - what might have caused that fuse to go.
Usually it's associated with a battery change - terminals touching something they should not, OR, one battery being fully charged and/or ok and the other being down. make that connection and a rush of power moves from one battery to the other, killing that fuse.
You decide.

I don't typically run it low. I was in Washington on the coast where the fuel prices are stupid now (not unlike CA). I was only way with the motorhome down the coast into Oregon where I can fuel the Jeep and Motorhome for about $1.50/g less. I wasn't planning on driving but more than a mile and on my way to a gas station to just put a couple gallons in it when this happened. Not typical. Not planning on it again, but at least the fuel was not the problem.

Yeah, some of the cables and items were not strapped down or tied or bolted. I really wish Jeep left space to put more items in there. The diesel is CRAMMED in with so little extra space. I have to wedge items where I can. Will probably do a little more research to see who has made and is selling what to help overcome this constraint.

What happened to you, sounds pretty similar to what happened to me, Thanksgiving weekend of 2023. With the exception of the low fuelšŸ˜‚. About a half a mile from my house, as I was almost at a stop sign, the engine sputtered and died. It restarted and I was able to round the corner when it died again. It restarted for a couple of seconds, just enough to get past someone’s driveway. I tried restarting it again when the poltergeist showed up. It was similar to what you said, about wipers and lights going crazy. Didn’t wanna deal with it that night so I disconnected and isolated both negative battery cables, removed the IBS, and walked home. I watched some YouTube videos on the topic. Lite Brite channel specifically, had good info. I went back to my rig in the morning and took a jumper box with me. After hooking up the jumper box, the vehicle did start. As soon as I removed one of the cables from the jumper, it immediately died. Right about that time a fellow jeeper pulled up. Thankfully, he was familiar with what was going on. He carried a 1’ long, terminated battery cable, for just such an emergency. He explained that the Z tray, (fuse array), had a blown fuse and wouldn’t stay running unless you jumped N2 and N3, on the Z tray. When he was done, I hooked up the jumper box and it fired right up and stayed running. I went to the dealer and had to leave it overnight while they did some research. They were unfamiliar with what was wrong so, they called corporate and an engineer diagnosed it as such. They said the Z tray, usually blows fuses on start up. Or at least in this situation it did, as I restarted several times. Thankfully, it was still under warranty. In addition to the Z tray, they replaced both batteries. Second time for battery replacements. I no longer do short drives with the JT as that was the real culprit in my case. Don’t need to beat a dead horse on that topic, so I won’t. I keep it on a battery tender daily and haven’t had an issue since then. I’m planning on keeping a spare Z tray in my rig.

Yup. You can get the Z fuse pretty cheap on Amazon and have a couple as spare. If it happened once for no apparent reason, it could happen again, and if I'm out in the desert somewhere, I really want a spare with me.

I would only buy such a spare fuse on Amazon if it was genuine MOPAR issue. No way I'll rely on that cheap Chinese crap electric stuff out in the wilderness. There's a reason they are cheap and sold by sellers with names you can never pronounce. If it doesn't say MOPAR, I close that tab.

The only reason to blow a fuse is excessive current flow - that means there's another problem. The fuse will never blow if all else is fine. I suspect a bad battery in the mix.
