Help!! Evening all, new on here, need some help. My discovery 3 cut out while cruising at 50mph. I just lost all power but no warning lights at all. Still have full electrics and engine turns over. The low pressure fuel pump still wines when you turn the key and the belt is still on the back of the high pressure fuel pump. I was going down the crank sensor route but when I turn the engine over, the taco moves. It bounces up and down a little so I’m not sure if that will be the issue. Other than that I’m lost as to what to try next?

Hello and welcome
best to ask over in the disco section of the forum
