So I just removed my dash in my 2001 gt to replace the heater core and when I reassembled the dash and all the counter parts the car won’t start. Has power to everything and the dash grounding straps are making proper connection but she won’t even try to roll over. But when I take the dash out and only have the steering column connected and the gauge cluster connected with one grounding strap connected to the steering column and the other to a good ground it starts. Any ideas? kinda lost here. None of the wires are pinched so i dont know what it could be

 

Check your neutral safety switch if it is a manual or PRNDL if auto.
