I'm fitting an immobiliser to my car and looking through the diagram one of the points to immobilise is only written as 'Solenoid Value' and has a symbol like a rectangle with a diagonal line across but with summat that looks like a two bladed propeller off to the side of it. Anyone know what that is?

starter

Nah, coils and starter are the other two. The starter is labelled as a rectangle with diagonal only

injector live?

Dunno here's a picture of the symbol and just says Solenoid Value

Possible spelling mistake?
Maybe should read 'Solenoid valve'.
Do you have one in the fuel line?
Certainly looks like the symbol for one.

I'd concur with the mis spelling of solenoid valve and go so far as to say it's probably for a diesel engine pump solenoid valve.

Fuel cut off probably.

Fuel cut off sounds good for me. Cheers fellas.
