Check and make sure the vapor return/vent line from the gas tank is not broken of disconnected.

You will find this line going from behind the gas filler, running right along the tube going to the tank for the gas.

Pump keeps shuting pff when putting gas im


Emma,
Take the nozzle out a little and lower the back of the handle a little. This should stop the back pressure which makes the pump cut out.

2003 Chevrolet Silverado 4.3 V6 with MFI. Engine ran not start.


Well it could be numerous if things but you want suggestions...So here's mine..Your gas tank might be vapor locked...This is caused from over filling your gas tank with gas over the years..Its when the pressure in your gas tank becomes greater than your fuel pump. It wont start until the pressure in your gas tank becomes lower then you fuel pump...Sounds crazy...This got me once...I didn't understand it...A lot of people (including me) Go to the gas station and get that extra 50 cent after the gas nozzle clicks off...over time that extra gas will run down the vapor lines intended to burn fumes....Like when you fill a gas can to cut your grass...If you sake the gas can it builds pressure and bows up. But with time that pressure will go away...Well saying that...Your gas tank needs to vent to....So your car burns not only gas but fumes...If you keep over filling your car with the extra gas it cloggs up your vapor canister intended for fumes or vapors...The gas will will go into that canister and clogg up the charcoal that's inside it. (Breaks it down) then the vapors can't get to your carburetor where it supposed to burns it. So what happens is the pressure in the gas tank becomes greater than your fuel pump and then car won't start..Are you with me? Lol Its crazy..Putting a different gas cap can cause the same thing...Simple test...When you open your gas cap to get gas.. Do you heat air sucking in.. Yes you can hear it....A lot of times loosening the cap let's the pressure out and the car will start right up.....Thus might not be your problem but worth telling at the gas pumps to other people..... Just trying to help

How to cut a trap door on 2000 silverado to access fuel pum


The easiest way to access the fule pump is to lift the bed or drop the tank. I have lifted the bed on many occasions. Just remove the bolts that hold it to the frame, but leave the two at the rear real loose, That way when you lift the front of the bed it will stay on the truck. Once it is lifted high enough, you can easily access the pump from the top of the tank. Cutting a "trap door" in the bed is not recommended as the sparks from cutting might ignite the gas fumes. Unless you take the bed off of the truck totaly, I wouldn't even attempt it.

What is the best way to access the fuel pump to repalce it without adding expenses? They want to cut the floor and do it. Will this cause problems in the winter? We live in Michigan with a lot of deep...


Too bad GM doesnt provide a cover to access tank without dropping the tank. I would think creating this "hole" would be quite the endeavor and done correctly would add quite the additional time and expense. Decline cutting holes and drop the tank in order to service the pump/sender. Any reputable repair firm should or would never recomend this measure in order to access the pump in the fuel tank I would hope....

Gas pumps continuously cuts off during fill-up


I had a similar problem with my 1999 S80. Give this a try. You don't need any mechanical experience. At no point will you come into contact with any gasoline. This is a five minute fix if it's what I think it is.
Background: when you gas up your car, it goes down a tube to the gas tank. There is a vent on that tube to let off gas fume pressure that can build up in the tank. If the vent gets clogged pressure builds up in the tank. Modern gas pumps shut off when that pressure comes back up the tube from the tank. I think if you clean out the vent with a Q-tip you'll solve your problem. At least, it worked for me.
  1. Get a flashlight and some Q-tips (I suppose anything long and pokey will do).

  2. Go to where you put the gas in (you don't need to open to door or take the gas cap off).

  3. Crawl under the car behind the tire and look up with the flashlight to about where you'd put the gas in. You should see something like the picture below (taken from my 1999 S80). Note that at the end of the red arrow, you can look up inside the tube a bit? When I was having this problem I could only see what looked like white cotton inside the tube. It turns out it was an old spider's nest. The spider was long dead from the gas fumes, but his nest made it impossible for me to fill up my car!

    (fig. 1 - a vent for the tube that leads to your gas tank)

  5. Place a Q-tip in the hole indicated by the red arrow. Swirl it around a bit. You shouldn't have to jam it or be very forceful. The Q-tip should remove any blockage.

    I suppose it's possible that when you open the blockage some gas fumes will vent out, so don't be smoking while you do this :) Now that I've said this, to be super-duper safe why not do this outside away from any chance of open flame.

  6. Go gas up your tank and see if it works. It did for me.

Good luck!

Smelling gas fumes in car after fuel pump was replaced


it is likely that the access plate that the pump is under is not sealed, most likely the O ring seal got installed wrong or cut and gas is leaking by it, not enough to drip on the ground but enough to smell.

Smell of gas fumes underneath vehicle near fuel tank


I also have a 2004 XC90 and a couple of months ago I had the exact same probelm... after multiple visits to my dealer's auto shop they figured out that it was the fuel pump. They replaced the fule pump and the smell disappeared. Good luck!
