LMM: No start/no crank 911 stranded

[Papapark]

2009 LMM
Just got the truck on the road after 19 months.

I had everything apart without removing the heads. Emissions gone, 72mm Danville, Hsp piping, injectors and twin cp3 kit...... the works.

Lights come on driving it.
Service Traction control, service stabilitrac, service trailer brake, park distance disabled, glow plug light came on, engine light on.

Ran the diagnostic, NO CODES STORED. Truck was still running fine.

Turned it off, turned it back on, all the same warnings popped up, but when I turned the key to start position, NOTHING. The head lights still turn off, and everything looks normal there, but no crank.

HELP, PLEASE

Weird electrical gremlins like this usually come from bad or intermittent ground connections. If you had the truck apart I'd suspect that one of the grounds either didn't get reattached or the ground bolt didn't get tightened down all the way and it's causing an intermittent connection.

Check the bail plugs on top of the engine and your ecm/tcm if you unplugged them to make sure that they are fully locked and check all your battery connections and grounds.
