DEF Pump went out!

I purchased a new 21 jl rubicon diesel last month and upon delivery thats the first thing I checked. Most of the fuses were not properly seated. Guess not all dealerships got the email.

Same here that’s the first thing I check was the fuse. And all the fuse was not seated. I think a lot of the issue that people are experiencing could just be loose fuse. This can also cause a short and cause more issues
