I wanna thank yall! been great help. turned out to be the module. all the grounds and positives were corroded and needed cleanin. Surprised it had any power anywhere. After all the cleaning and adjusting the cpm as cruiser suggested. my cmp cam up to .42 - .51. still had no spark. checked referrance from pcm to module, still good 5V. tried old school thinkin to fire coil and nothin. so, went with module seein that all inputs were good and still nothin. Fired rite up. again, Thanks a bunch!!!!

P.S. on the engine to body ground, i moved engine ground to the next head bolt up just to be easier on me. Also, cleanin connections, a die grinder with a cookie as i call it, is much quicker than sandining.
