Apparently vaseline is almost identical... I see now what PJ is for (petroleum jelly) - duh! Yes, PJ will work
If you bypass the FC with a piece of insulated wire and switch on briefly, the motor gets a full press of the pedal. If it still doesn't go, the FC is definitely not at fault.
Be careful of course, but bridging the FC wires is a very easy way to eliminate it as the cause.
