Hello fellow members. While taking the old dashboard out I had to disconnect a few things . Here's the list
1-radio
2-passenger airbag
3-Iunplugged socket from this sensor which is located under the drivers kick panel .(it looks like a sensor. I don't know what it is)

Also ,while removing the instrument cluster the round bezel from the ignition immobilizer became loose and the wire inside was hanging like this
is it supposed to be look like this?

long story short I decided to start the car with the radio,airbag and the instrument cluster disconnected from the car and the engine cranks but it feels like is not getting any fuel .
It has solid red light with the ignition on and the ses light aswell. fans kick on a few seconds after.
I put everything back together but still no luck.
Could the immobilizer be broken?
thanks for your help!

 

I think that "round bezel" with the wire hanging off it is the NATS/IVIS antenna, that's how your car detects the signal from the RFID chip inside your key. It will not start without that signal, it will crank but not open injectors/spark. I've never seen one fall apart like that before, it should have been around the lock cylinder.

Yes this is NATS/IVIS preventing the car from starting, that's why you have a solid red indicator light.

I think the one in the top picture is the ambient air temp sensor. Again, I've never actually taken it apart to see what was inside. What are you using to disassemble your car? Everything unbolts/unplugs and comes apart very easily, it shouldn't be falling apart like that.

 

I disconnected the battery and the ecm to no avail. I also tried to reprogram my keyfob (take key in and out six times before 10 seconds ) and the hazard lights dont even flash. I will get a nats antenna replacement soon and I will let you know all the details. Im pretty sure that's what is causing all this ! thanks for your reply!

 

I got it fix. It was the immobilizer/antena. I grabbed one from a wrecked yard and problem solved!
