2015 wrecked ltz won't try and crank

[Chrisr112]

Replaced some wiring and checked the engine bay fuses. The secondary air pump runs non-stop and no clicking when I turn the key. Power to the starter main wire.

 

[Chrisr112]

Idk if there is a service manual or wiring diagram that would be helpful.

You might want to add....

....some details.

1.4 turbo, Automatic, transmission harness was broke in wreck but I changed it and fixed the fuse. Fully charged battery. Dad and everything lights up but my code reader won't read the codes.

Won't read what codes? Body codes, transmission codes, engine codes? Details man. Lots of details....

Run over something and rip the wiring harness kind of wreck or someone smash the LF corner of the car where the ECM and main harness is kind of wreck?

Airbags pop? Remote keyless entry work? What happens if you try with the key fob remote start? Tried starting with the shifter in neutral? Any other positions to see if the shift cable is out of alignment?

Does the dash indicator properly show the shifter position if you move it to R, N, D or M even when not running?

You hear the fuel pump prime when you turn the ignition on?

Door chime when key is in ignition and door is open?

 

[Chrisr112]

No codes at all. Dash indicates check engine.hit pretty hard on the driver's side. Rewired the transmission harness. The headlight wire is still broke but figured it shouldn't have anything to do with it. Steering wheel and both passengers airbags deployed.

Not sure where it would indicate gear on dash, I don't see it anywhere. Do the reverse lights come on if it is in reverse but not running? Bc they don't.

I'm pretty sure the fuel pump primes

Door chimes when key is on and door open

Key fob works as should and when I try electric start it just flashes the turn signals and nothing after that

 

[Chrisr112]

Could there have been something when the transmission wire broke it gounded something out or sent something to the computer as a fault? Now the computer needs reset or something, and is that like dealer only stuff?

 

[Chrisr112]

Anyone know of a safety feature or anything?

 

[Chrisr112]

This is a photo of the dash before I hit the key. Is everything normal?

Not totally familiar with the automatics, but if its not indicated what mode you're in. Drive, neutral, reverse etc, then the car won't start. Why not replace the whole harness from a junked car. Might be a bit easier and with less headaches.

You should probably take the car to the dealer. They can perform more exhaustive test. You instrument panel looks like there may be some real problems there.

Call a tow truck and scrap for parts. Probably done. Show more pics of vehicle.

Had a Chevy tech stop over and on the wire harness I repaired there were 2 white wires I switched up which were the communication wires..... It runs now just finding out the radiator, fan, and ac condenser are not the same from the 1.8 to the 1.4. bought a 1.8 parts car :-(
