2011sierra hd wont start

[topdj]

My truck was fine one minute and next morning wont start. No click battery is newer truck has 27000 miles. Thinking it may be ignition switch i tried remote start no dice. Did hear fuel pump run for second. I picked up a new starter but have not had a chance to install. Battery terminals look clean and tight. Dash stays lit during attempts

 This is a gas 6.0

 GROUNDS FIRST.  Im not sure where they are on your year truck, but grounds being corroded can cause these issues.  Obviously could save a ton of money too.

I'd disconnect/clean/reconnect the battery connections, as well as the connections on the starter.  And check for codes from all the computers in your truck (so, you need a fairly advanced code reader to do this).  And test the battery (just cuz it's not that old doesn't mean it hasn't gone bad nowadays).

 

It could be the starter, but sounds like it hasn't been used that much w only 27k on the truck.
