tested obdII connector was getting power to 3 prongs, dont know if/which one was the power prong though

after turning motor over several times the cel went off?

all fuses look good

tested for power on the connector to the coil and ignition module and niether had power?

I had the same problem in my 98 and it ended being the electrical ignition switch. I had no spark also, replaced all those parts and nothing. I ended up taking off the covers where the ignition switch is and played with the two big yellow and red wires and sure enough it turned off and on when I did that. Hope this helps
