SOURCE: 1990 Ford F150 won't start after running out of gas

After running out of gas, the system is still full of air/vapor. In the fuel injection system, the pump will run momentarily each time the ignition is turned on. You should be able to hear the pump. Each time the pump runs it purges some of the air through the return line back to the tank. Try turning the ignition on and off about 10 - 20 times to purge the air and vapor and fill the system back full of gas.

If you find my suggestions to be helpful, please share with us some details so that others may benefit from knowing the whole story. Thank you!

SOURCE: 1990 ford f150 cross over valve location

Please Help ME by Remembering to RATE ME Thank you Vrey Much !!!

This vehicle does not use an external fuel tank switching valve. A supply check valve in the fuel pump assembly opens when the outlet pressure from the energized fuel pump exceeds the opposing check valve spring force.


R E C A L L 1991
THE DUAL FUEL TANK SELECTOR VALVE MAY MALFUNCTION AND CAUSE AN OVERFILL CONDITION IN ONE OF THE FUEL TANKS, RESULTING IN AN OVERFLOW OF FUEL PAST THE FILLER CAP.
THE OVERFLOW OF FUEL PAST THE FILLER CAP CAUSES A FUEL LEAKAGE, WHICH CAN RESULT IN A FIRE WHEN EXPOSED TO A SOURCE OF IGNITION.
REPLACE THE DUAL FUEL TANK SELECTOR VALVE.
SYSTEM: FUEL TANK, AUXILIARY.
VANS AND LIGHT TRUCKS WITH DUAL FUEL TANKS PRODUCED IN THE FOLLOWING PERIODS: F150, F250, AND F350 LIGHT TRUCKS BUILT BETWEEN FEBRUARY 28, 1989 AND JULY, 1989; ECONOLINE BUILT BETWEEN FEBRUARY 28, 1989 AND FEBRUARY 11, 1991.
NOTE: FORD HAS AGREED TO RECALL THESE VEHICLES BUT PARTS ARE NOT YET AVAILABLE.PARTS WILL BE AVAILABLE IN DECEMBER 1991. YOU WILL RECEIVE A LETTER FROM FORD ADVISING YOU WHEN TO SCHEDULE AN APPOINTMENT WITH YOUR DEALER TO HAVE THE RECALL WORK PERFORMED. IN THE MEAN TIME, YOU CAN TAKE THE FOLLOWING PRECAUTIONS:FILL EACH TANK TO ONLY 1/3 FULL. IF YOUR VEHICLE LEAKS FUEL OR IF YOU SMELL FUEL, STOP USING THE VEHICLE AND CALL FORD AT (313) 446-4654 AND ADVISE THEM OF YOUR PROBLEM. REFER TO FORD SAFETY RECALL NUMBER 91S39. AN OPERATOR WILL TAKE YOUR NAME AND TELEPHONE NUMBER. A FORD REPRESENTATIVE WILL CALL YOU BACK

I have a 2000 F350 diesel manual trans 4X4 200,000+ miles that is having a power loss, idles fine but when you take off it starts to sputter like a gas motor with a stuck choke. Just changed the fuel...


If you changed the fuel filter 2 weeks ago, I would first verify that the fuel filter is good! Dirt from the tank could have clogged it up again.

The next suspect would be the fuel pump in the tank.

What does the vehecile act like if you rev the engine up in neutral? Does it show any signs of fuel starvation? If so concentrate on fuel system.

sometimes the tank decomposes from the inside flaking off and clogging filters, pumps, etc. always a good idea to completly remove tank and flush to check for same when changing the fuel pump. if that's your problem, you will need a new gas tank

Ran out of gas ,now drives rough 1990 150


Hi there it is most likely dirt in the fuel filter,when you run out of gas you bring up all the crud from the bottom of the tank and if your lucky enough that it hasnt ruined your fuel pump it should be just the fuel filter needs the dirt blown out of it a really easy job to do good luck
