no its not, what pump relay have you got fitted? should be 67, 80 or 167. bottom right slot if CE2 (hazard switch on column) or slot 2 if pre-90 (hazard switch on dash)

It should run all the time the engine is running, on turning the ign, it should prime and thats is it.

i wonder if the earth trigger from the ecu has just been grounded somewhere. gonna be a tricky one to track down!  the issue is if you have a crash the pump wont cut out, so its a safety thing.

look at fusebox pin G1/3, see if its been spliced to ground somewhere. if it goes off into the engien loom then you'll have fun tracing the issue.
