One question about the tank situation?
Was the truck equipped, from the factory, with dual tanks, (a switch in the cab and 2 fuel doors in the bed, for quick reference) and now you on have one functioning tank, or only 1 physically installed. Or was this the fairly rare, true single tank system?
Reason I ask, my last IDI only had one tank, (the rear) because the other was physically removed. But the FSV, all the lines for the tank, and the switch were still there. I eventually had to bypass the valve (actually ran new lines from the rear tank to the engine compartment due to continually having leaks. After the bypass, and getting the glow plugs working properly, it would start with just a bump of the key.
All this being said, you need to get the cranking speed up. Even in the second video, it's not spinning near fast enough.
This is a video from @Macrobb here on the forum. He does a good description of what needs to be connected to make it run. But the important thing I want to show from this video is how fast it is turning over. He is starting an IDI Turbo on a stand with 1 good battery. If you are using 3 and they are good, it should jump to life......
If it's not spinning this fast, or very close to it, you need to address cranking speed first. Even if fuel does get through the injectors into the pre-cups, it will not start turning over this slow. Honestly, I'm not sure you could get a gas engine to start turning over this slow........
