Fuel gelled and tried to start it. It tried once and tried again and nothing starter didn't do anything. Put new starter in and same thing. Checked all the fuses all good. Starter relay in the dash clicks. I noticed head lights don't dim or go out or the inside lights don't go off or dim when I turn the key to start it. Tried the starter wire under the hood and starter just clucks won't spin over. I can turn the motor over by hand so it's not hydro locked. What am I missing?????? Please help???

I know little about 6.0s in particular, but verify your batteries are good, connections are very clean and the cables going to the starter are in good condition. I had a very slow start condition with my 7.3, and clean terminals fixed it remarkably well.

From there I’d see if there was a way to jump the starter to see if it’ll crank.

Depending on the results of that I’d chase from there.
