Coolant flush issues

[BeaterComanche86]

So I decided to do a coolant flush today, full discloser this is my first attempt at this “easy” job. So I drain the coolant from the radiator, and reserve and flush the radiator with some hose water. Fill both back up with water and start the engine. Engine is running just fine while I’m getting it to temp. So I turn the truck off because I think it’s good but on second thought I could have warmed it up more (idiot lights so I don’t know the actual temp) so I go to run it again and this happens... Any idea why she won’t start anymore? Any help would be greatly appreciated.

Sounds like your batter is dead or you need to clean the positive and negative terminals first.

Issue resolved, while cleaning my battery terminals I noticed that one of the crimp ends broke off so I put a new end on and it started right up  beginners mistake I guess. Now I can get back to flushing the coolant. Also thanks to @Fryedaddy for the response.
