Sounds to me like a dead battery,,,, if most electrics are dead. or weak. or just green lugs on same..... clean them yet
jumper cable start car? yet?
2007
which engine, ?
its a no crank,
ill not guess, and send you to the $800+ poor house...
id say check fuses first, not above.TIPM
always do that on any electric failures and cranking is all about that.
as is scanning the PCM
is your battery dead.?
do head lamps work (key off and on)
is battery at 12.6v or more? cluster V gauge 12v not lower)?
http://jeepdied.com/no-crank.html
this car is (USA and not diesel) WK gas
GAS
does not use The TIPM to do that.
the page shows how the WK works to crank.
the 45RFE 545RFE 5-45RFE transmission is there.
and the MB
The NAG1 (new automatic group1) is A Mercedes W5A580 trans,
the transmission
here is how it works if starter and battery work
and hot wiring starter tests pass.
see this,? the PCM knows(red arrow) the transmission is in park
if yes, it pulls in this relay. below.

if the relay is dead, the PCM must be scanned.
if it shows the TRS errors, or others, bingo.
what do i do (lacking scan tool)
I hot wire the starter,
if that fails i replace/charge or correct battery or cables or starter unit if bad.
ok hot wiring starter now works.
so next up is the KEY LINE (p/n permissive's)
still no cranks, i measure the relay voltages cranked. stater relays dont cost $800.
I measure its 4 pins with $20 walfart meter, I then know whats going on,! not guessing ever.
87must go hot? 12v (10 to 12 typ) cranked
if not pin 85, must be 0v cranked, if 12v there, then the PCM is blocking starts.!
end of zero scanned cars and guessing.
or start with a voltmeter at that relay.
less bending over...
the voltages on all 4 pins, tells the full story.
cranked. (i promise) post results.
those gear lights, are a big clue,no?
no car can crank if the PCM thinks
there are gear shift errors.
by law. the TRS makes that work.
but if battery voltage is low ,the computers will just go crazy.
in all cases of no cranks battery is always first look.
its weak technology, 1900's
lead and acid and and can fail in 3 years. from new. as can the green corrosion there,
easy.
so be all over that battery first.
the starter is silent not even a click from it.

I have been replacing a lot of TIPM's lately. Basically the fuse panel under the hood. I have done checks for them recently and found it traces back to the main chip. Have the codes read.
