live feed to the fuel pump - wiring diagram needed

Help please.

I need a wiring diagram for a S reg Alhambra.

Ive got a problem with the live feed to the fuel pump.

All works fine if I put a direct feed from the battery to the fuel cut off valve, but as soon as I remove it the engine cuts.

Ok Ive got a wiring diagram but need help.
I think Ive found what the problem is can anyone confirm or not my final analysis. (before I pull all my hair out)

OK on j491 fuel cut off relay Ive got 12v to terminals 2 3 and 6 and 0v's on 8 and 4 except on the odd occasion that all works then Ive got 12v to them as well.

If I put a link between 6 and 4 engine runs but in limp mode.

On J52 coil relay Ive got 12v to 1 3 and 5.

In conclusion I think the engine man ecu is up the swany.

Or is it something to do with immobilizer? engine cranks but does not fire.
