Pedal position does nothing during cranking because the fuel rack is already at full fuel. RE: the governor is trying to maintain idle speed but the pump isn't turning.

A _slight_ bit of pedal in order to keep idle speed up a few hundred RPM over hot idle could be helpful on engines that don't have a high idle / cold advance mechanism.

You want to avoid a cranking RPM to 2000 + at start that a 1/2 or full pedal gives, doing so is hard on bearings as oil pressure has not built yet.

I tried starting it tonight but I found a huge oil leak. It's just one of the oil cooler lines so it isn't super major but still annoying to fix.

I had my garage warm, the oil pan was hot, and the rest of the engine was warm when I tried starting it but it didn't make a peep. I had the glow plugs on for 30 seconds before I tried. Cranked it for 15 seconds, waited 15, and cranked for another 30 without any sound of it starting. Now that I have the down pipe on it I can't see if any smoke is coming out the exhaust. The engine was really easy to start back when it was in the car so I'm not sure what to do. Do I risk spraying in some ether?

Sounds like the glow plugs are not getting power. Can you verify voltage to the plugs?

Yeah they're powered, I hooked a brake light into the circuit and I can see it come on as well as hear the solenoid click

Does it sound like it's getting fuel? Or smell likes unburned fuel?

It is in the owners manual to start the engine in cold weather IIRC.

I don't know what it would sound like if it's getting fuel but I know the pump works because i was able to bleed the injectors. I might try bleeding them again though because it's been a few months and I was having fuel delivery problems. Before I put the down pipe on it (back in the summer) I could see smoke come out the exhaust
