Yesterday, I removed the battery and charged it.
Today, I installed the battery and the truck started right up!!!
It appears the PATS had to be reset. I know this is the case because... I had installed a push button starter switch to get the truck started. Since I am curious, I tried to start it with the starter switch and it would not start (key in on position). Then when I turned the key, it would not crank. So I disconnected the battery. Waited a minute or so and reconnected the battery and it started right up!!
The takeaway from this is to DISCONNECT THE BATTERY, WAIT A FEW MINUTES, RECONNECT THE BATTERY and see if your truck starts up.
Now, I will have to reconnect the Clutch Pedal Position Switch (CPPS), since I bypassed that as suggested.
I just want to say THANK YOU to all that pitched in to help me. I really do appreciate your time and efforts.
