2005 Crown Vic police interceptor

Our son was driving down the road & the car died. A mechanical good Samaritan
stopped to see if he could help. He reset the fuel pump shut off (which had been
tripped), but that didn't solve the problem. Battery is good... Any suggestions? Does
Ford have a built in self diagnostic? (on my Dodge, if you turn the key rapidly on, off,
on, off , on, without actually starting the engine, it will run a diagnostic & display codes
or done on the odometer. Wasn't sure if Fords have something similar?) Thanks!
