Time for an update.
Yesterday (Thursday) The weather allowed me to go out and hook the battery charger up. This is the kind of charger you would find in an auto repair shop about forty years ago, it's stout. After about five minutes I put the key in the ignition and the engine fired right away without any spray. I did this a couple of times and it was the same result. Then I unhooked the charger and tried to start it, the starter would spin but the engine would not even try to fire even with the spray. So it looks like battery time(My son had to replace his battery in August, His wife a new battery about a month ago, my wifes car 2 weekends ago) so it's my turn now. Before I finished my work I noticed the belt tensioner was at odd angle, the bolt that holds it in place had snapped off. I spent most of today removing the support bracket and then drilling and easy outing the rest of the broken fastener, it had seized in the tensioner arm. In 25 years of owning this truck I have replaced several batteries but It was always obvious that the battery was going dead. This problem started in July, it was an odd problem but I didn't think much of it until we weren't able to solve it. I hope I've learned my lesson, I should have come here first. Thanks for taking time to help, all suggestions will be noted and added to my Haynes manual. I won't be able to get the new battery until sometime next week, after I install it I will report back.
Thanks; Byron Oh I did spray around the intake and connections, everything seams OK.
