Might look at the ICP sensor wiring. It is a little 3 prong wire coming out of the sensor on the passenger side valve cover. I had the similar issue, turns out the ICP sensor wiring was bad. I replaced the wiring harness from Ford, (it was about$75), spliced it in, and has been fine ever since. My original plug was corroded, and not getting the proper signal to the computer. And same as you, no warning lights in the dash, no CEL, just cranked and no started. Alternatively, maybe pull the plug, and clean it out a bit. Also, if you pull the plug, and there is oil in the sensor, then your sensor is bad, and will need to be replaced.
