I guess. However still have yet to see in writing or on a schematic that the Crank Sensor actually can provide a signal directly to the fuel pump. Fuel injectors, yes, it does.
the sensor itself does not power the pump however if the ecu doesn't see the signal from the sensor then it won't send the ground to the fpr to turn pump on

I was asking about towing because that jostle could easily trip the inertial switch but surely you've punched that button by now. I'm, sorry, Omar... I'm just not an electronics guy and I don't know how to solve this. You will be a Land Rover EXPERT when you solve it.

Right. These actually aren't bad though. It gets bad when you have to have the proprietary software and everything has to be vin-specific.

Make sure you note where the bolt spacers are so you install the new one correctly.
