tbi vs carburator
i have 1989 D100 with throttle body, 318 with what i believe to be about 90,000 miles, thinking about converting to carburator. i am concerned about when computer is eliminated, what will io have reroute as far as electrical if anything. the reason i am considering doing this is i dont believe these computers can be repaired or replaced and i would also like to improve my fuel milage. any help out there?

It's rare but they can go bad. It also controls ignition and if you have the od trans that's another thing. Stick with the efi, If you are concerned about the pcm look up the # on yours and see what you can find on ebay. I had a 90 and no issues with the pcm and it had just over 200K when i sold it.

Look for local parts trucks too. The TBI ones are the least popular around here. $50-600 for a whole one IME. Then you get the PCM and all kinds of extra goodies.
You can approach TBI economy with a carb. What you sacrifice is cold-start drivability, usually. OD trans and/or axle ratio ratio change can help the fuel economy.
