The first thing I’d say is to make sure it really did run out of gas, or did the alternator crap out and drain the battery dead. The fact that it clicks is something. Twist the battery cables and both ends to starter solenoid and ground bolt. Then hammer starter to make sure bendix drive is engaging, then turn engine by hand or pry bar at flywheel to ensure bendix is engaging flywheel teeth. Wiggle or twist positive ignition wire on solenoid to ensure contact. Cross positive ignition terminal and main hot wire to starter with screwdriver to bypass ignition and wiring to engage starter. Make sure NO gasoline fumes are in engine space when you do this. Battery must have enough charge for anything to happen. If still nothing, charge battery. Hope this helps.
