engine won't start

Thanks again for all the feedback and and for the wealth of knowledge from some real gear heads here. My main drawback in figuring this thing out was not being in a good place with time to do so. Once we were towed and settled in a campground for the weekend, I was able to do some serious troubleshooting on Sunday. It was the red hot wire on the ignition sw. that wasn't getting over to the pink wire that feeds the ECM. I jumped the gun and made a mistake with allowing the same tech. that the tow service brought along, coming out on Sat. morning and accomplishing nothing. With my temp. bypass sw. we were able to proceed on our way and to our immediate destination and NAPA was able to get the sw. overnight. I have it installed and ready to go now, but will be here for awhile, so we had plenty of time on our hands, once arriving. Haven't removed my bypass sw. laying on the doghouse as yet and will chalk that one off to paranoia and just leaving it in the off position for now.
All exterior lights continued to work with the outage and my little 16amp bypass sw. never got even warm for the next 175 miles or so, although I never ran the overhead fans and not sure how many relays might be in the circuit to limit the amount of current draw through the ign. sw. itself.
