Could just be due for a full tune-up. How many miles has it been since it has been serviced? How many miles are on the oem spark plugs? May need to take it to a certified technician and have it diagnosed.

SOURCE: 1986 F150: Rear gas tank results in engine sputtering/dies

i think u have a bad fuel pump, switching unit does nothing but not allow fuel to be pumped from tank to tank, for example if useing rear tank lets feul flow to engine not iti nto frt tank,when it goes bad you will see gas flowing out of frt tank because its pumping into tank from rear tank,good luck.check fuel preasure w rear tank is on.

Testimonial: "Thanks for the response. I checked w/the Ford dealr parts guy who said each tank pumps directly 2 engine. Not sure how it works on other trucks tho."

SOURCE: Mercedes SE 300, acts like its coughing, my

Have the cars on board diagnostic system read. An autoparts store like Autozone will plug in and read the codes for free sometimes if you are at their store. Or just visit a trusted local garage and ask for a read. It only takes a few minutes to read the computer with a industry standard OBD2 code reader. I bought one on ebay for 35 bucks for myself.

If you have codes but no continuous "Check Engine" light showing on the dashboard you may have missfires related to certain controls/sensors slowly going bad on your engine. Or you could have something outright mechanically wrong with the car like a vacuum leak or a clogged EGR valve.

Also, is this coughing causing other driveability or fuel ecomony or power issues? That can also be indicative of what kind of problem you are looking at.

If this problem persists but is minor....eventually the computer will send you the check engine warning. Sometimes it takes 1000's and 1000's of missfires to get a check engine warning! That's because of tolerances built into the software the cars computer is using.

Good luck!

The tank is not venting. The regulator is like a relief valve for the fuel injection. So it would not be the regulator. Evidently the vent on the top of the fuel tank is not venting properly.

It could be moisture yes, could be electrical if the wires and plugs are older they will crack and in humid or rainy weather they would be worse-or when they are cold.

My ford was spitting and sputtering and backfiring. i changed the plugs and wires, made sure of the gap, and it ran fine for a few days . thought my problem was fixed and then it started doing it again...


Use a gas treatment with a full tank of premium gas and see if it clean out your fuel system. It could also be your MAF sensor. There are ways to clean them but you have to be careful not to damage it.

When putting gas in the tank of 2009 F150, the gas overflows when the gauge shows only 5/8 full. I cannot fill the tank.Any suggestions


Tank is full. The level swith is bad. Have to pull the bed to get to the fuel pump. Pump and fload is all in one. If you work on this yourself, replace the whole unit with Ford parts, do not use after market it will not last. If under warranty just go to dealer. Good luck..

My Trailblazer started idling and running rough intermittently. We thought bad gas. We were on a trip and used a gas teatment to get rid of water. Did not help. Delaer thought the same but now says...


I'm guessing you have the 6 cylinder engine and not the 8? I don't buy what the dealer told you. If you're really worried about a little water in the fuel system, run a bottle of Seafoam through the brake booster/ gas tank, that will solve any water in the system. Change your fuel filter after you do this, it will be dirty now, due to the Seafoam cleaning your gas tank. Wondering what would need to be "sealed" if there were a little water in a cylinder due to bad gas??? There are 6 coils on this engine, one per cylinder. If the coil goes bad, you would get a check engine light for a cylinder misfire and it would be consistantly running rough. Since it your problem happens intermittently, I'd check the wires going to the coil for any faults. I'd also check for a possible 02 sensor starting to go bad.

1 thought, does this only happen when ever you happen to have the defroster on, or the A/C? If so, I can help you solve your problem easily.

How do you get the gas tank out of a 1998 g20 van Van would not start, put new starter on it, but when it was cranked it sputtered and died. I thought it could be bad gas because it has not been moved in...


  • You need to start by removing almost all the remain fuel, fuel is very heavy
  • best method is to use a lift to get it off the ground, you could also use ramps to get the room need to drop the tank
  • disconnect the filler spout from the side of the van
  • disconnect the fuel lines
  • use lifting equipment to support the weight of the tank, make sure this is stable
  • carefully remove the tank straps and lower the tank, watch the fuel pump wiring and any other connection that may be in the way while lowering the tank.

2005 Ford Five Hundred engine sputtering


Dear anew32, Wed 2-11-2009 3:43am EST (USA)

Do you often run your gas tank to near empty?
If so.......
This sounds like it may be as simple as cleaning the water or gunk out of the gas tank which is what I always do 1st because it's easy and inexpensive.
If your fuel is contaminated with gunk, grime, water and/or bottom junk like rust this will cause stalling and rough riding!
Try spraying a can of starter fluid in the air intake and see if it runs! If it does, it's most likely bad fuel or clogged injectors so....
Fill the tank with High Test, Add some dry gas and a good fuel system cleaner or 2 or 3 and this should dissolve all the gunk and clean the injectors! Read & follow the cans' instruction carefully.
If this cures the problem never let your gas tank get below 1/4 and especially never run it to empty as this is when the gunk and/or water will enter the system!
Hope this helps!
Good Luck!
