thats normal for it to keep ticking. mine does it even when the ignition is on.
are you sure you hvae the correct version? (internal/external) also if you have all the dials on the back zero'd out it doesnt do anything. try the manual dail on the the front first and just crank it all the way to the right, fuel cut will tell you that its working
then start playing with the other ones. i turned mine up and then start to back them down until it is just under FC
