1994 Firan "Europremier" chassis wiring diagram? New owner

Nothing special about the driveline. Any tech familiar with basic wiring and fuel systems for mechanical Cummins C engines should be able to get you going.

The big issue is whether the diesel is still good. If not, MUCH cheaper to pay to have it drained and disposed of than to destroy the injection pump. A good diesel tech can "smell it" as a first indicator and then take a small sample from the primary fuel filter/water separator after running the engine for the first time.
