RAN OUT OF GAS LAST NIGHT IN 2001 DODGE 1500 PICK UP w/ 5.2L ADDED 4-5 GALS BUT NOW MOTOR STILL WONT START. CHECKED VALVE ON FUEL INJECTOR TUBE ON TOP OF MANIFOLD WHILE TURNING MOTOR OVER BUT DIDNT GET ANYTHING TO SPEW OUT. COULD I HAVE LOST THE PRIME IN FUEL SYSTEM? I HAVE RUN OUT OF GAS SEVERAL TIMES BEFORE BUT IT NEVER FAILED TO RESTART AFTER PUTTING A FEW GALS OF GAS INTO TANK.

In tank fuel pumps are cooled and lubricated by the fuel in the tank. When you run a car out of gas or very low, it pumps a lot of air through the pump which overheats it and causes some severe wear and many times, failure when they cool off.
You will need to use a fuel pressure gauge to verify this
