Hello since nearly 3 years i have massive starting problems with my disco. I start the engine i starts goes out and i have to start the bleeding procedure to get it starting again, when the car is running there is no problem while driving. I figured out that these starting problems occur most of the time the tank is half empty. I have changed nearly everything from the fuel pump, the fuel lines in the back, the fuel injector washer, the wiring loom, fuel pressure regulator and the filter housing. Does anybody have an idea? Many thanks (sorry if my english is not perfect)

 

Intermittent stalling issues are often the Crank Position Sensor. If you replace it, use only a Bosch unit. The other brands last a year or so.
