I have a Ford Everest, cranks but does not start. The reason is there is no fuel supply from the pump to the injector rail. If I spray quick start the vehicle starts and drives smoothly. No vibrations or jerks. When the car is warm it begins to produce blacks smoke until it cuts. It never starts by itself unless you spray quick start. I have replaced Injectors, Diesel Pump, Crank Sensor, Cam Sensor like 3 times this set of spares. Still my Everest is not running ok. My diagnostic machine is not reading any modules only RCM. I checked all fuses they are ok. Kindly help
