Yay !!!!!! Okay the positive battery cable was the problem. I went to Chevy to get a new cable and wouldn't you know it, part is discontinued and they have none in stock. Could get me one in 10 days and it would cost $78 CDN....... Damn !!!!! Forget that. I went to Napa and it cost $19.95 plus tax, but the cable looks cheap and I'm not really impressed with it. I fixed it and the car has power, and she fired right up. Runs awesome. Now I just need to tune it better with the laptop. Here comes a huge learning experience. I also installed dual electric fans. I should also wire in the knock sensor, the torque converter lockup and the A/C to the XFI, but one thing at a time. Thanks to all the members for their help and suggestions, much appreciated.

Note to forum moderators, could I get my name changed to XFI RS, I think it suits me. Thanks.
