P0370 = Fuel Injection Pump Speed/Position Sensor Signal LostYou might try cleaning up the cannon plug on both sides with some cannon plug cleaner or CRC brake cleaner and ensure all the pins are straight. Some silcone dielectric grease may help ensure a good sealed connection. If this does not fix the problem, you may be looking at a bad injection pump.
