I'm starting to suspect that I have multiple, separate issues. Looking back over the recent issues with the truck dying on the road, the vacuum in the gas tank due to lack of ventilation made a lot of sense (LMJD, thanks for that). The trips between stalls seemed to get shorter and shorter, until I left the truck sitting for several days in which time I'm sure the pressure normalized some. The new vented caps came in so since the truck was running low on fuel anyway, I decided to take a test drive up to the nearest gas station which is 8 miles away. The truck started up with the tiny spritz of ether (I know I still have air intrusion since I haven't gotten my hands on the parts to get after the fuel heater) and then it drove pretty great all the way to the gas station. Ran it on both tanks, but mostly the back one. No problems with stalling and the power seemed normal. So I topped off both tanks and went to start her back up. Now recently I've had no issues restarting the truck after it's warm, but this time I turned the key and absolutely nothing happened. Keep in mind the truck had just been running literally 4 minutes earlier with no issues. I attempted to jump the solenoid with the key in run, and got nothing. So I ran a wire from the negative post of the battery to the small center post of the solenoid. It clicked when I did, but then did nothing when I attempted to jump the solenoid while it had power. The starter didn't turn, nothing. Checked all of the connections to ground, etc and nothing was loose. I brought the batteries back to the house and checked them, since I hadn't brought my multimeter to the gas station. They both have 12.6v.
So now I expect that I've fixed the fuel tank ventilation issue, but discovered another. How does one properly diagnose an ignition issue in the column? Radio and accessories weren't even receiving proper power. I thought I heard the speakers try and turn on in the truck but nothing else was coming alive in the dash. I've never torn one of these things apart, but I am planning to go back to the truck in the morning with all my tools. Parts stores open pretty early, so I'm open to all suggestions.
