Heavyd Thanks this. -

It looks like SPN:2023 FMI:14 is a gauge cluster fault. Can you get the engine scanned?

Won’t let me make a new post so I’m gonna say this here I’ve got a dt466 that would start but when I went to check the voltage on the ipr valve it arced off a ground and now there’s no ecm communication. Any help?

There should be two fuses in the battery box. One has probably failed.

You likely popped the 5 amp ignition fuse for the ECM. From now on, when making a post, we need to know the year of the truck. You might have a pre-egr DT466 or EGR-DT466 which are different engines and different wiring. The 5 amp ecm fuse is going to be in the main fuse panel, ether under the hood on the left side near the firewall, or in the cab infront of the passenger seat. Again, this depends on the year and why you need to include that information.
