After fixing the governor weights on my '20 T4 55, it decided not to start. Bled the fuel system till my hands cramped and used ether to get it running temporarily. What's stopping it from firing up on its own? Any advice appreciated.
 
If you bled the system and did a good job, then it's probably not air, but I'd still check the injector line nuts. Losen them and crank until you see a steady flow of fuel, not bubles. My second though is the fuel shutoff solenoid. Turn on the ignition and wait for a click. It's not the loudest in the world, but you'll hear it if you're paying attention. If there's no click, you probably have a problem with the electric like blown fues or a bad relay
 
Got it. I'll take another look at those injector line nuts to make sure they're not causing issues. As for the fuel shutoff solenoid, I'll crank my ears to max volume and listen for that click. If there's no sound, I'm gonna hope it's just a blown fuse and not some gremlin in the wiring. 🤔

It's probably air sneaking in somewhere? Or maybe the pump isn't working its best. Best thing to do is to double-check all those fuel lines and seals. For real man because sometimes a tiny leak can be a big problem. I watched Final Destination recently so I'm going crazyyy over the tiniest details HAHAHA.
 
Thought I should circle back with an update and a big thank you. She's running like a top now. There was a hairline crack in a fuel line seal that was a real bear to find but that was the issue. Thanks for pushing me to leave no stone unturned.

PS
That Final Destination thought made me spit out my coffee.
