its not electronic , its a mechanical pump.
You need to losen the 3 nuts holding the pump, fix the pump puly to the pump bracket with 2 small m6 bolds (ie the bolds that hold the belt cover) losen the center nut of the pulley a few turns , gently tap the nut with a hammer until the pump axle pops free from the pulley.
Now you can swap the pump without changing the timing belt.
Will be done within the hour.
