I saw this happen to an outboard motor of all things. The fuel pickup tube in the tank had a crack in it lengthwise letting air be sucked into the tube when there should only be gas. Try sucking through a straw with a split in the side and you'll see what I mean. If gas is covering the crack, no air leaks in but when the fuel level drops down to or below the crack it begins to run very badly. You must drop the tank (when empty) and replace the tube or the sending unit as an assembly.

It is sludge and water in the tank. When you fill it water goes to the bottem of the tank and the good fuel goes on top where the fuel pump is.

Gas gauge working good but truck stalls at 1/2 tank

Fuel gauge


I don't think you could trust that either. Sounds like the sending unit in the tank is messed up, so it may never read correctly. By now, you must know the approximate miles per gallon it gets, so until you get the gauge fixed, you should go by the number of miles you go to know when it needs gassing up. Just as a ballpark figure, a '97 Sierra, city driving, maybe 15-17 mpg? I really don't know, you could google it I'm sure.

2005 ford explorer spot trac acts like is running out of gas but has 1/2 tank


hi,

sounds like a combination bad vacuum leak and/or fuel. find the egr valve and temporarily plug the line going from and to it and test it, check all your vacuum connections, you would hear it hissing. those plastic vacuum connectors get brittle and crack about this time . Ive had a few electric fuel pumps fail that way, half dead. bout time for one of those. check fuel pressure also.if it threw a code and the check engine light is on then you can have the code read at autozone for free.

How many miles do you have on it? The fuel pump is in the gas tank, I have a 97 explorer and around 75k miles the fuel pump went out. After talking with other Ford truck owners this was pretty common. Its not a cheap repair unless you are willing to drop the tank yourself.

Just filled the gas tank in my 2006 f-350 turbo diesel super duty (6.0), started the truck and the guage showed a full tank. Drove down the road about 1/10 of a mile and the guage dropped to dead empty...


A loose connection on the sending unit could cause the problem but also moisture in the tank in cold weather could also be a factor in which i would add fuel line antifreeze to a full tank of fuel..........Hope this helps you out.

My 1998 Ford Explorer runs rough under hard acceleration


New plugs and wires?

Double check to make sure that you've got the routing and firing order right... if you have 2 switched, the car may still idle well but then pop and sputter on harder acceleration.

The next step would be to run some "Complete Fuel System Cleaner"... If that's the problem, you should see results within 20 miles or so.

Poor gas mileage


I hope your friend put some gas stabilizer in the tank before he store the car.

I will put one bottle of ISO-HEET (red bottle) to the fuel tank + fill-up and let it run down to 1/3 tank.

Fuel up with a full tank Chevron gas for one more pass.

Black smoke when i start engine, very rough idle.


sounds like possible a sensor went bad or is loosly connected. O2 sensor??? Also check the air filter. Sounds like whatever it is, is making the truck run rich----that would be the black smoke.


Hope this helps
