So it turns out this breakdown was partially my fault Before I get into that, this morning the first thing I tried was unplugging the TPS, no change. Then, just for the heck of it, I disconnected the fuel line running to the throttle body, and sure enough, no fuel. Not sure why I didn't see the injectors pulse then, but anyways, I went halfway back and disconnected the line before the fuel filter, and still nothing. I could hear the pump run, so I figured the tank had to come out. I dropped the tank, and when I went to pull the sending unit out, I realized what happened.
Back when I got this truck, I installed a fuel pump, sending unit, and tank from a parts truck. When I went to go put it in, I noticed that some bug or something had packed the return line with dirt, and I couldn't get them cleaned out, so I had to cut the line to be able to clean it out better. I just slipped some hose over the ends. I figured it would be tight enough to not cause any issues. Turns out I was wrong. It must have had too much pressure on the assembly while I was motoring around some corners while going up that hill, and popped the pressure hose off at the pump, so it was just pumping right back into the tank.
I ended up stealing the brand new pump/sending unit I had already installed in my other truck and popped it in, fired right up. Now as a bonus, the fuel gauge works too!!
