Injection pump
I am new to this so I hope I did every thing correctly.
hear is the story,
about a week or so ago I noticed a drip coming out of my vent on my afc housing on my 93 d250. After doing forum searches I came to find that my fuel pin o-ring was leaking. The forum I got this information from had step by step directions on how to replace it. This seemed very straight forward so I went and bought a rebuild kit and started disassembling. Every thing was going great took me about 4 hours to replace the fuel pin o-ring, throttle shaft o-ring, and various crush washers. Slapped it all back together and began priming and bleeding. After I recharged the battery 4 times, I came to the realization that something isn’t correct. Any ideas? Thanks!

Thanks for replying Edwin.
I have somewhat ;but, I still have bubbles coming out. It almost seems as if I don’t have much fuel pressure at the injectors. I don’t have a gauge to to check. Lift pump was replaced 200 ish miles ago. I’ve turned it over so many times to the point where no air should be left in the lines.

I don't know how deeply you went into the reseal but it's possible you got something wrong internally but if the injector lines are pulsing fuel I would discount that theory.
You need to fill out your signature so we know what you're driving and what mods you've done. Also it's helpful to know what city you live in.

When putting the top back on the IP did your back out your fuel screw, or use some fishing line to hold the throttle fulcrum back and out of the way? If you did not then you most likely damaged the fulcrum and the truck will not start due to this.

Look up indexing the throttle lever as well. You can get some really difficult starting issues if it's indexed 1 tooth off.
