    I'm rebuilding a 220k mile 86 automatic for a friend, I'm close to reinstalling engine and transmission, I'm concerned about the EFI, will it work after sitting for 20+ years ?
    any good advice would be appreciated.

    Did it sit un-used for 20+ years?

    My 95 Tacoma is fine. A ton of these old trucks are fine when maintained and used.

    Yes, my friend overheated it in the late 90s and it was parked under tarp in pole barn until this spring when I started on it

    Engine and transmission are rebuilt and ready to go back in but I don't have much faith in the EFI after being parked for 20 years so I'm thinking about a carb ?

    What about having the efi cleaned and tested?

    That was my original plan but when I was disconnecting everything several of the plastic electrical connections crumbled and a couple of the vacuum connections broke because they were all so brittle

    I'm also concerned about the automatic transmission working correctly without the fuel injection so I think I am going to try to fix the fuel injection before I buy a carburetor
