No fuel delivery

Having fuel delivery problems ? It's not the fuel pump relay ! You probably have a bad fuel pump driver module . Pull you spare tire down an look on the frame above ! Watch this
F150 Expedition No Start P1233 Fuel Pump Driver Module

You probably have an electronic ignition system to go with those fuel injectors. It sounds like it runs just long enough to empty the fuel out of the injectors, which means there might be a vacuum problem. I'm a carburetor person myself. Are you sure it sound like it NEEDS gas or could it be flooding?

Do you have 2 gas tanks?

Check the exhaust pipe to see if the catalytic converter is plugged. Engine may have back pressure not allowing fuel to cylinders.

have diagnostic codes checked to see if you have a cam or crank sensor fault. make sure fuel pressure is at the required pressure, just testing to see if you have fuel at the valve is not enough. replace all spark plug wires. if you replaced two then all are just as old and even when they "look good" does not qualify as "they are good". Replace coil pack. start up drive away happy

ARE YOU SURE THE FUEL PUMP STAYS RUNNING.
FUEL PUMP FAILURE IS VERY COMMON FOR OLDER FORDS.

You have an excess fuel delivery problem. Black smoke indicates that too much fuel is entering the combustion chamber. If this vehicle has a carburator, check the float bowl level. If it is injected the main things to look for would be a stuck throttle position sensor or an injector that is not closing

WHEN DOESN'T CRANK,TRY RELEASING FUEL FROM FUEL RAIL AND SEE IF FUEL COMES OUT,WATCH YOUR EYES. LOCATED BY #7 CYLINDER. FUEL SHOULD SPRAY OUT,LOOKS LIKE A TIRE PRESSURE VALVE ON FUEL RAIL. NOTHING COMES OUT THAN FUEL DELIVERY PROB OR VAPOR LOCK?

Have the fuel pump checked it may be weak.

if this is a 1980 F150, emissionwiz is correct in saying it has a carburetor, if your engine runs on ether, you do not have fuel supply to the engine. Check fuel delivery at the front of carburetor, should be a line screwed into the carb, may be connected by a rubber hose, remove this line and crank engine, look to see fuel is gushing out of the line, if no fuel the pump is bad, check fuel lines back to pump for leaks, replace leaking lines if necessary. If you get fuel then your float inside the carb is stuck, and the carb will need some attention, hope this helps, let me know
