it will run once for mayb for 1 second and die, if i try to start again it will jus crank and crank and nothing happens untill i reconnect the cold start valve then it will start with more cranking but still not on the key. hot start is fine tho always on the key

fitting efi in afew weeks anyway but thought if it had been the relay it would have be nice for it to start first time for the last few wks on mfi
