Took motor out to change sub frame I drove it in the garage, changed sub frame and put motor back in and now it won’t start. But, lost key in the meantime so went to dealership and got new key and immobilizer and now I don’t have anything when I try to start it. It did say starting disable do to theft but when I got new Immobilizer that went away. Does the fuse box under the hood have to be grounded? I am pretty sure it is a ground issue because when I turn the key to acc all the gauges go up then down but when I turn the key, they go all the way up and just stay there and light head light stay on and done light stay on bit dash light go out.

Hello, yes, there is a Ground for the under-hood fuse block, it's near the passenger side head light, I'll post the diagram below, I know it's easy to miss a Ground when doing a motor job. If you need any other diagrams let us know, Ill pull up the rest of the Ground diagrams just so you have them.
I'm sorry I put the wrong diagrams up. Let me get the correct ones
Diagrams 12 to 18 are the correct ones for your vehicle. Very sorry about that.
To simplify things, I added the under-hood fuse panel with a non-OEM diagram. It's easier to see where the grounds are for that Fuse Panel. Those are the Grounds for the Fuse panel mounted near the passenger side strut tower. And some extra Grounds.

Sorry, there was a slight technical glitch yesterday. These are all the Ground diagrams 1 to 4 and diagram 5 is the under-hood Fuse panel Ground diagram.
