I have a Disco I. Having issues withe Starting. I replaced the Crankshaft Placement Sensor but it did not seem to cure the problem. I've been turning the key on then off and on again three times and it hits every time. What do I need to do next

 

Sounds like it's not fully priming the fuel rail and it's taking 2-3 times to do so. I would check your fuel pressure and look into replacing the fuel pump.
