I bought this truck it cranks over good but won't start had this code on my scanner. Says mechanical systems not ready. Vin is 1HTWDAAN9CJ615484 has 7.4 liter engine. Any ideas what would cause this code?

That fault code does not seen to exist. I would contact the
NexLink support people and see what they have to say.
Possibly your scanner needs a software update.

Can you use the cruse buttons and get any codes on the dash? Check small power and ground wires from the batteries to as far as you can follow them. Probably have multiple connections along the way. Only takes one bad one.

I got codes thru cruise active codes:

Spn. 51, 3464, 132, and 158

Previous codes:

2791, 597, 1552, 2000 and 520465.

Where do I look these up?

You can only retrieve body codes with the cruise switches. With each fault
displayed in the instrument cluster there should be a SA number for Source Address.
The SPN and a FMI numbers as well. You need all three to look up what they mean.

SPN or Suspect Parameter Number 51 is throttle sensor.
FMI or Failure Mode Identifier 11 is Root Cause unknown.
SA or source address 0 is engine. The instrument panel can't
tell you what the problem with the throttle sensor is.

If it sat for several months without battery power to the "Keep Alive" wire
to the engine ECU it will probably need to have the engine ECM reflashed.
A lot of the parameters will go to the default setting and there are a lot of them.
Reflashing is faster than manually resetting them all. The mass air flow sensor will
need recalibration as well. However the engine should still start and run.
There is a throttle body on the intake manifold where the charge air tube from the
cooler connects. The throttle plate closes when you shut the engine off. If it is stuck
closed it will stop the engine from starting. It might be a good idea to pull the rubber
tube off and the key on and look down the throttle body and see if the plate opens.

Thinking back like said above^^, U.S. Foods had a MaxForce that set in our yard dead for a month.
By the time they picked it up it needed re-flash.

I looked at butterfly today and it was open. It doesn't move at all when cranking. With key on engine off it is open.
