Hi All,
This one is going to be a toughie I think.
It occasionally blows the EFI main fuse.
The customers usual mechanic has started having a look. He fitted a new fuel pump and when that was unsuccessful he opened the loom up in places (bit of a shame as a lot of "forensic" may have been lost).
Looking at the diagram this feed is a permanent supply to the ECU and is also the EFI relay fed supply to loads of consumers (EGR sol, ISCV, fuel pump mainly). My intention is to split the circuit with several fuses and see which one goes next time. I was just wondering if anyone has knowledge of a common problem I am not aware of, possibly relating to known chafing points etc.
