From a couple US Navy techs:
A TF30 engine was pulled for inspection, and was found unserviceable while on the trolley/cart. But it needed to be preserved for shipment to overhaul.
The maintenance crew attached a hose to the fuel pump inlet to suck preservative oil into the fuel system, then applied shop air to the starter to turn the fuel pump. However this engine had a self-powered ignition alternator on the gearbox, and there was enough JP-5 left in the lines that the engine lit up and started to taxi across the ramp.
It encountered and disassembled a brick wall before the fuel lines ran dry.
