2011 Tundra cranks, won’t turn over. ODB link error

My 2011 SR Tundra will crank but not turn over and start. I checked all fuses in engine box, and most in drivers kick panel. Hard to see the main fuse through the sight glass. I tried hard to take it off and it was too difficult and gave up. There are two fuses related to fuel pump I wanted to check.

the dash has some lights not working. I nothing lights up on turn key to on and I thought everything light up for a second. Flags gauge and other gauges not working.

ODBII Scanners get a linking error.

Red key immobilized flashes then goes away so seems like not the issue.

from what I read could be a loose wire in the dash. I’m at the point of giving up.
Wanted to check if anyone has experienced this or has ideas? Seems like a few unique issues all at once that might be a clue that jumps out to someone, and any advice would be really appreciated.
Thanks for any input.

 

@ColoradoTJ can you move this to gen 2 please?

 

Does it crank as in start is turning the engine over or no? You say it cranks but then say it won’t turn over. A little confusing.

Sounds like you have a major power delivery issue. Did you check with a voltmeter to see if any of the fuses in the interior box have power?

Have a good battery?

I would still be looking for bad fuses, loose power wires ect. You might not get communication from scan tool because the ECM has not power to respond, give spark ect.

 

Check ecu connection, double check ecu fuse also
