A new automotive application article about a Citroën Xantia refusing to start is available.
A 1999 Citroën Xantia had a new starter motor fitted, after which it would not run anymore. While cranking it would fire briefly and then die. The car’s battery had been disconnected for the starter motor job. A crankshaft sensor code was logged and thus the crankshaft sensor was replaced, regardless of the good signal. Later the ECM was replaced all with no positive results. The question was if the immobilizer could have reset itself by disconnecting the battery. Proper measuring revealed what the real problem was.
