Some disagreement in here!

L8 does not have fuel pump prime temperature compensation. It does have fuel pump prime with key to on (3s iirc), it does not need the crank position sensor connected to the ECU at all for this to happen. It does then need crank position input for the ECU to recognise engine rotation therefore ground fuel pump relay to run pump.

Don't get too stressed gents, COVID 19 is much bigger in this world currently.

If that pump has sat for 9 years, change it, you will also probably find crispy wires on your phase sensor. If the CPS has a white wire, change it. All good practice from experience. Makes sure you do have fresh fuel. 6 months old stuff is garbage.

Enjoy
