Alright, here is the latest. For those of you just tuning in, check my last update....
Anyway, been dealing with the dog and talking to shelters, lawyers, sheriff etc. Been a PITA.
Then, the truck started acting up again, been having passlock problems the past few days. It's giving me the theft fault, flashing "security" 10 mins till i can start it. Since the ignition is already resistor bypassed it means the truck is loosing the resistance of the resistor I soldiered in, which in my mind tells me it's having a connection issue. So I unhooked the batteries, reseated all the associated connectors involved with the passlock system, and found where that circuit is grounded....
Turns out, the ground for the passlock is a large ground bolted to the back of the block (there are two ground studs in this area). Upon inspection of the area, I found there were indeed two ground studs, however all 4 wires were on 1 of them instead of 2, and everything was nice and dirty. One of the studs is actually holding on a coolant blockoff plate.... Upon closer inspection, I see coolant sitting there next to it.
Jackpot! I think I found my passlock problem and coolant loss problem, all in 1 felt swoop. So, remove all the grounds, clean, etc. Scrape the blockoff plate and head surface, and re-install with a new gasket and a thin film of ultragrey. Reinstall all the bolts and grounds in the proper locations. I then unbolted and cleaned the frame grounding strap and battery grounding cable to the block.
Throw more coolant in the tank, and turn the key... Wait to start... Security light goes out. Woot! I've have 3 successful restarts with no passlock problems! Time will tell if the coolant loss was fixed, lets hope so!
