And my wife has given it a name already and the thread title updated.


Just bad fuel, or?6hrs, 1 replace fuel filter message, 1 reduced power message, 1 jug of DEF, and $230 in fuel later and we are back home. Time for beer.
Before I installed a lift pump, I got one or two replace fuel filter messages. Haven’t seen it since. Also got rid of that stupid juice issue too.Not sure. We pulled over and added a jug of DEF even though it said the level was ok (stupid Chevy doesn’t have an actual gauge) and let it sit for a minute or two and then turned it on and never had another issue. Gonna swap the fuel filter out this morning before my sister and nephew and bil hit the road. We ran 3 tanks of fuel through this truck in less than 48hrs so I doubt it was bad fuel.
No need to delete for a lift pump. It could help the cp4’s life expectancy though.It’s my parents truck so no deletes haha.
Yeah the low def problem went away with the DEE- lete. And the nox sensor issues. And the def temp sensor issues and… oh, the regens! Damn, it’s been so long I forgot how much I hated it!I read that as def problem went away as well as filter messages
