Okay, here is the deal. I bought a 2000 Xantia from a friend that needed some body work in the front. The engine ran okay, but seemed to need a tune-up. The guy finished the body work and had the bright idea to take the computer out of the car nightly so that it won't get stolen. Yes, did I mention that the car is in Liberia, West Africa. Since his engenius idea, the car refuses to start. When I put in the code it cranks but doesn't give any spark to start. Does anyone know if the computer needs to be reprogramed by the dealer? Any help you can provide will be greatly appreciated.
