SAIPA Pride

For decades the most numerous car in Iran, derived from the Kia Pride (itself a Ford Festiva design) and sold in saloon, hatch and van bodies under a family of numeric names. Mechanically minimal — a small SOHC four with basic injection on later cars — so the diagnostic path is short, and the corpus's universal causes (connectors, earths, supply voltage) resolve a large share of its codes.

The engine is Mazda's B3: 1,323 cc, 71 by 83.6 mm, eight valves, one overhead camshaft. en.wikipedia's Mazda B-engine list gives those dimensions and puts the engine in the Kia Pride; fa.wikipedia names it for the Iranian cars directly. Which half of the car the documentation describes is the useful part — Mazda and Kia material describes the block, and the injection does not come from either of them. It was carburetted until 1384 and multi-point injected afterwards, and the injected engine is not the stronger one: the same 63 hp, reached at 5,200 rather than 5,500, with 2 Nm more torque. fa.wikipedia credits Siemens and Sagem with the conversion, on one source, so expect the management and its wiring to be documented in Persian if at all.
