I recently purchased a water flood 2023 Chevy and I get the code U0078 and I thinking it’s the starter but what do you guys think would help me get this car started

 

You have a faulty control module due to the flooding.

 

yes it is the 350a fuse has no power and every time I turn it on it shorts
any idea what to do next?

 

find a power distribution diagram showing all the loads the fuse feeds. Start unplugging loads on the circuit until the problem goes away. When the problem goes away you have found the circuit to focus on.

you could run a headlight off the circuit to keep the fuse from blowing....when you unplug the short the headlight will glow brighter. they do make specific tools for this...amp hound is one i think.

 

The one I circled is the one that doesn’t have any power I’m thinking this is the one connected to the starter is it?

 

i don't have access to 2023 diagrams.
