So since you replaced the battery harness it hasn't started? Did the old and new wiring harness look the same? Are all the connections intact and tight?

I attached the starter relay wiring.. Can you tell me if pins 30 and 86 have 12v when you remove the starter relay?

You either have a bad key or skim module. A scantool will be needed to d terming the issue and program either a new key or module.
