I'm having same trouble I have a 1992 6.2 no turbo it will start run for 10 seconds and then die but if I can get it up to 50 mph it'll stay running I don't understand it
Idk if you still have the truck but mine is 1984 k10 6.2 n I got some wiring in couple different areas missing connection and jw if you can take some pictures so I can get an idea of what goes where ?
I wonder if there's a check valve in the IP? Radio? press and hold the far left horizontal button or far right. The cracked fuel line was normal on the end, peek inside to look for deterioration, I think they were OK, GM uses da good stuff!
Bypass the rectangular fuel filter management box. Its a leaking nightmare, I know. I was lucky in that the previous owner had installed a Racor marine filter/water seperator on the engine compartment firewall in my van that does the job with way less problems. you will have to install a "T" fitting for excess fuel return as well
The ZIP ties WAS a good idea! I don't like the worm clamps, they mangle the hoses, and break, and strip... Junk, get some spring clamps, like on the rad to overflow bottle, and sideways needle nose pliers

the 2 rubbers under the 2 valves on the fuel filter need to be replaced
The air leak would be before the lift pump, and you need to get ZIP ties w METAL locks, 10x the price, but they LOCK!
exact similar problem on my '87 chvey 6.2 silverado big-dooley, did you work out something?
DId you ever get it to work? I have the same problem. I have replaced every fuel line in the truck except for the return lines.
How in the hell does your 6.2 crank so fast?!? Look st one of my videos. Doesn't crank at half the speed
High torque starter. I have one. Buy about 20 starter bolts. It snaps them off on a regular basis.
your lift pump is bad
