The old CIS-E cars ('91 and older?) are pretty simple, and will most always run if the fuel pump and ignition works, sometimes it is getting it to run well that can be challenging. Problems are relatively few and easy to chase using a test light, good DMM, and resistance substitution box.

The later 104 cars though, a lot more parameters affect the engine's health, including its many self-protecting and limp-home features.
