Well checked all fuses, everything appears to be working as should be. Stumped for now so if anyone has anything else I should check, it’d be greatly appreciated.

Hoping to take the truck off road.. so I hope my truck doesn’t get disabled I checked and re did some grounds that are attached to the frame underneath the drivers side, any other grounds I should check for and clean up? Yeah I haven’t found anyone who has posted a definite solution yet. The character of an old Chevy I guess

Could it just be me getting unlucky and a mix of different things happening? I’ll do a full run down of all fuses after work, I’m hoping it’s as simple as that.

I am stumped. New to this forum so I am hoping I’m posting this in the right area, but desperately needing help on my 2004 Chevrolet Silverado 2500HD 6.0L So I went on a camping trip and while I was off roading, my gauges stopped working. The speedometer and my revs still work. But it doesn’t underline the gear I am in and all other gauges are dead. Doesn’t keep track of my kms as well and when I went to plug my obd reader in, it doesn’t work anymore too. It did this a few times before it completely stopped working. my radio completely died too. It started to reset itself when my gauges were acting up and died around the same time as when the gauges completely died. I hope this is making sense, but I’m at a lost and idk what to do. I’ve checked a few fuses that I think would cause it but nothing. I know the gauges are a common problem with the truck but why is nothing else working? Coincidence ? I’m thinking of replacing the ECU / ECM, maybe it got fried while off roading (didn’t go through that much water). No chewed up wires either. If anyone has a list I can go down of what to check, that would be amazing. thanks

Truck is a 2004 Chevrolet Silverado 2500HD with the 6.0L V8 gas. I am a little stumped with this one. I am getting P0156 (O2 sensor code), P0157 (O2 sensor low voltage Bank 2 Sensor 2), P0300 (random misfire) I have been trying to fix the misfire thinking it was bad manifolds. Replaced the gaskets and the manifolds with headers, yet the codes all stayed. Then I replaced the O2 sensor Bank 2 Sensor 2. Even though I replaced the O2 sensor, I am still getting the same old codes... That means that it was not the O2 sensor itself and that there is another underlying connection, correct? I have a slight exhaust leak before the O2 sensor but it has a sleeve and clamp over it (still leaks a little but not much). Could this cause all 3 codes? Trying to get the old girl running right as I tow quite a bit with it and I feel like this is causing a lack of a lot of power.
