You will need to bypass the immobiliser on the pump. I'm not 100% sure how to do it on the Lucas CAV.

you just swap the stop switch, its on top of pump fit the earlier pre immobillizer type

this is from memory so might not be 100% , last time i played with it was years ago !


if the engine was from a PATS immobilizer car :
To get to the shut off solenoid you will need to remove the pump , cut away a brass shroud on the back of the pump which covers the solenoid and there will be 3 black wire 2 need an ignition live the other needs earth , try different combo's until it starts easily (it may be possible with the pump in situ but i found it easier with it removed so i could see what was what)

non PATS immobilizer :
as above but the solenoid isn't covered with a shroud
