This weekend I noticed my gauges stuck in whatever reading and stayed there until I turned the truck off. If I started it back up, they would be fine. Ran again, and two were maxed out and the other two were moving like normal. Now today I ran it, all the gauges stuck at a reading and now they wont move period!

Checked ground and that was fine. ESP take a dump?

 

Since all the gauges are on a single bus try disconnecting one gauge at a time. Might be a problem with a single gauge. I have performax gauges and have not seen this problem but that is what I would do before suspecting the ESP.

 

Checked and reseated all the wires at the gauges. Ground is fine. All the wires are in looming, and rubber grommets so I dont think its a shorted wire.

The gauges work about 50% of the time. I can turn the truck off and back on and the gauges will work again. Sometime all them will move all the way to the right when I turn the truck off. I noticed both the turbo and pyro gauge will move a little and in fourth with the truck totally off, and sitting for hours.

 

Sounds to me like you have a key on power to a constant hot?

I had this same problem during the first week after the install. Turned out to be a wire that was not all the way into the crimp connector for the inline fuse. It pulled right out. recrimped and problem solved. That was months ago.
