Fuel Pump Voltage, XJR
Anybody know what voltage is applied to the fuel pumps for an XJR?
Is is constant? I know that the pumps are variable speed and controlled using a PWM signal from the REM and additional fuel pump module for the XJRs second pump.

Full battery voltage I believe. At least 10.5V for sure.

The pin point tests don't give an expected voltage
I'm going to back probe with the engine running and see what I get for the left and right hand side pumps
I'm doing the pin point tests now for the wiring between the ECM and the REM and Pump Module 2 but have come across the 5 point torx on the ECM connector, so will have to get one of these before proceeding any further.
