Land Rover Repair/now no spark


Hello again I just asked you about my ignition and my disco 2 stalling. I went and bought a fuel filter and crank sensor. And replaced battery again. Now I have no spark. It cranks over but the plugs don't fire I haven't replaced the sensor or filter yet because its parked on grass. Is there a sherader valve where I can tell if gas is getting to the engine? How do I check to see if alarm has immobilized the motor. Sorry to be a pain.

If the crank sensor is bad the plugs will not fire.   If the vehicle was immobilized it would not crank at all.  As for fuel pressure - you would need a professional gauge kit with the necessary adapters to tap into the line and measure pressure.  However, if there is no crank sensor signal there will not be any fuel pressure because the pump will not be turned on.  So the first step is the crank sensor
