Had my FPR installed yesturday, and noticed that when the ignition key is switched to ON there is no pressure built in the fuel rail.... Isnt the fuel pump supposed to pump when ingnition is put to ON??
So if this is right how does the fuel pump power? is there a relay somewhere, Or does it run off the ecu???

Thanks

the pump does come on when you turn the key to on. I wasnt sure of this until when i actually had my car in a small garage and when the key was 'on' then the starter would make a high pitch whining sound, very quiet tho.

As for the connection, im 80% sure it comes off the ECU
