Unhook the fuel line upstream of the injectors and cycle the fuel pump. Dump fuel into a waste container.
My buddy bought a dead T100 that came from the bottom of a river (fully submerged over the roof).
Flushing the fuel lines got it running again after a full fluid change.
I've got stock springs from a 72 from when I installed OME a number of years back.
Shipping from MT to TX may be cost prohibitive but let me know if you would like to look into it.
I'm with @mattressking.
Rear pinion is loose. This happened to my truck a while back shortly after I bought it.
Get a new pinion seal and stake nut to limp it along until you can rebuild the rear 3rd member.

Take 2 lane highways where you can, be gentle on the throttle and engine load.
Toyota doesnt even recommend the 1st oil change until 10k.

If your AFR is reading at >35AFR your 02 sensor is either dirty or nuked.
I have a sniper on my 40 and it goes through 02 sensors. I installed a heat sink spacer and that semi-helped.
Id bet that if you take out the O2 sensor its covered in carbon.
It will be covered in carbon because the O2...
I installed one of these on my 2023 SR5 TRD. Its awesome and works 100% of the time.
Its not worth complaining about, all new Toyotas have this and the workaround is simple.
Takes about 5 minutes to install.

I agree. This 40 is very representative of a reasonable entry level truck in 2025.
I dont know the price paid - but 40s like this one are common - more common than the ones with no rust and OEM everything.
Finished the install, 3 evenings solo after work then a full day with a buddy helping out. The instructions are non-existent minus a youtube video, I figured it all out but would have been faster with less guesswork on which hardware to use in a specific location. Installing the winch control...
Starting the install on the Ironman 4x4 Apex Triple Hoop Front front bumper. I bought this several months ago but the winch was on backorder.
Unpacking the thing took over an hour. Ironman did a great job (too great?) with padding, tape, and cardboard.
These are 3 in 1 LED stop/tail/turn lights installed into steel pipe slices. Just an idea.
