1991 Ford F150 worth fixing?



Our nonprofit has a 1991 F-150 w/ dual fuel-tanks (164K mi.) which a friend inspected (he works on his own trucks & Fords) said has a bad starter and very low fuel pressure.
Can you tell me if it’s even worth fixing this old truck?

2001 Ford Ranger - worth fixing the AC?

What kind of shape is the rest of the truck? What do you use the truck for? Have you priced out how much it would be to purchase a new or newer used truck to do whatever it is that you use this truck for?
