First of all, i'm from Finland but i hope i can find answers from here for our problem and i apologize for possible bad grammar
We have a Cat 312B (couldn't find the model year) that one morning decided not to start, diesel injection pump isn't getting power but when we put 24v straight from the battery it runs. Oil pressure light turns off while starting and coolant overheat light isn't on. I couldn't find an electrical schematic for the engine, does anyone know where the power to the pump comes from? Straight from the ecu or throught a relay? Thank you in advance for your replies.
