Have a 2012 RAM 1500. Fuel pump went bad. It was replaced but when I got home, I heard the pump still running. Repair shop was closed so I figured I would take it back first thing in the morning. Went out and the battery was dead. Recharged the battery. The truck tried starting but wouldn't. Figured the fuel pump burned up from running all night. Took it back to the repair shop. They didn't mention that the fuel pump was bad, but said I now need a fuse box. There was nothing wrong with the fuse box the first time I took it in
Question: Did the fuel pump running all night possibly ruin the fuse box? I've never heard of a fuse box going bad.

 

On the older trucks, the fuel pump relay was replaceable. On the newer trucks.... it is not, and the entire TIPM gets replaced instead. A stupid design if I ever heard of one.... There are kits to bypass the tipm for fuel pump control though. Might chat with your shop about that....

 

The Total Integrated Powertrain Module (TIPM) failing and causing fuel pump issues in that generation of Ram/Durango, etc. is pretty well-known. The TIPM pretty much a fuse/relay box with some logic / control circuitry as well. Typically though the issue is the fuel pump relay fails to close and power the fuel pump. When I had my 2011 Durango I carried around a jumper lead in my glovebox, just waiting for my TIPM to act up and leave me temporarily stranded. Fortunately it never did. I never read of one where the fuel pump relay failed to open, but it's certainly possible, and possibly related. It's tough to say whether the pump failed from running all night or if the relay is now failing to power the pump, or maybe the fuse for the pump blew from increased current draw as the pump heated up. I'll suggest you start by checking the fuse for the fuel pump though.
