Hi Guys

As told in the intro subforum I am working on this Jaguar xj40 4.0 sovereign from 1989.

there are some problems which I would like to fix:
- Central locking system: If I put the key in the lock, I can lock the doors, If I try to unlock, I hear a significant click, but nothing happens

- Lightning bolt light: Fuse A2 in fusebox 2 is blown, I already tried to change it but it got blown everytime

- the boot can't be locked

- Water comes in near the floor on both sides near the fuseboxes, I guess from the frontscreen

- Anti-lock light burns with VCM: PAD so need to check brakes and sensors

- yesterday the check engine light was burning with fuel fail 26, but it looks like this isn't burning anymore after resetting.


Any Ideas or tips n tricks? I already found the xj6 haynes manual, but can't find a proper specific xj40 electrical diagram
