Need help. 1999 LS1 received new PCM. Hooked it up and and plugged in battery. Tried the relearn procedure but it never got pass step two. TURNED key to start position for three seconds then run position. Security light stayed on. no flashing. Then it went out after a few seconds . It's supposed to stay on or flash for ten minutes. After two day's iam lost. The car turns over and has fuel pressure but no fire to coil packs. Any info would be appreciated.
