Did Toyota ever produce factory diesel trucks for North America?
Yes. Toyota introduced diesel trucks for North America in 1981. The 1981-1983 models were available with the 2.2L “L” (or “1L”) normally aspirated engine. In 1984, this was replaced by the 2.4L “2L” engine. For 1985 and 1986, both the 2L and a turbo charged 2L-T engine were available. Toyota dropped all diesel options for USA after the 1986 model year, but they continued as options for Canadian trucks through 1988. Link to specs for these engines: http://www.geocities.com/MotorCity/Pit/9975/dataBySubject/DieselEngines.html Diesel engines were also available for the Camry and Corolla during roughly the same time period, but I’ll leave that for another site.
