Finally got somewere. Removed the IAC from the throttle body and she started right up!! Looks like the IAC is bad. So gonna replace that too. But would save me some scratch and eliminate for future possible trouble shooting if I could find a way to test the old IAC.

Is it possible to test an IAC to see if its bad? Or to test to see if
signal is going through it? To the computer?

Also, it looks like the wire harness connection is 2 positives and
then the negative ground is through the bolts to the throttle body?


Any info would be appreciated. Thanks,
