I had this problem with my 75. I'm pretty sure that's a failure of the "double relay" which I think is on the firewall in GTV6s - it's left the fuel pump permanently connected to 12V instead of being switched by the ignition. You can check by pulling the connector off the switching relay, I think it's the one on the left, which should make the pump go silent. If it's been trying to pump against an already-full fuel rail with the engine off, it may have got stuck and split a seal or something. There is a post about fixing the double relay at the AlfaBB: http://www.alfabb.com/bb/forums/alfetta-gtv6-1975-1986/162093-bosch-double-relay-0-332-514-121-et-al.html Cheers, Matthew. -- to be removed from alfa, see http://www.digest.net/bin/digest-subs.cgi or email "unsubscribe alfa" to [email protected]
