Thanks for your quick response! Yes the SES light came on as it was dying. I thought about the wires/plugs but it didn't make sense to me that they would all go bad at once. The plugs are getting fire, well I pulled #5 plug, grounded it with a jumper cable and turned the engine over and the plug fired. Can you get any info from OBDII after disconnecting the battery ? I did this to replace the starter, now with the car not starting I am unsure whether I can get any data from the PCM or not.

Its def not plugs or wires. Pull your coil packs off and underneith is the ignition modual. If you see that its corroded, lightly sand and clean up.
