Question about 2002 Kia Optima

Open Question

I can't put gas in my '02 Kia optima. How can I fix this?

No matter how slowly I pump the gas, the pump switches off as if the tank is full. I've had my valves cleaned out, and it works for one fill-up then back to the same problems.

SOURCE: I have a 2004 kia optima with 52000 miles on it.

Two things come to mind. You broke the pressure seal to the fuel system when you took off the gas cap. The fresh gas rushing in disturbs any dirt or debris on the bottom of the tank.
Next time you use the car when you arrive at our destination, simulate what you do when you fuel up. This will mimic everythig except the new fuel rushing in. If it is still hard to start you know it's something to do with the evaporative fuel system. If not, you need the fuel tank inspected .

Every few cents the gas pump clicks, no fuel gauge

Could be the fuel tank breather is blocked.
Lots of fuel tanks are wide and slim these days and formed to fit the body profile so they have one or more humps that are higher than the filler pipe entry. It would be quite impossible to fill such a fuel tank if the top of the hump(s) weren't vented.

Because the fuel tank these days must be a closed container except when filling, such vent pipes would be connected to a branch of the filler pipe above the maximum fuel level to ensure the tank can be filled and to minimise blowback during filling.

2004 buick century gas gage not working

Most likely a defective fuel level sending unit, located inside the tank connected to fuel pump assembly. Theres a possibility that you have a ground issue. So check that first as its easier. If the grounds check out then you have a few options. 1. Pull the fuel pump assembly and clean off the fuel level sender(tons of tutorials online for this). This fixed my problem for 10 months until my pump went out. 2. Replace just the fuel level sender. 3. Replace the entire fuel pump assembly (which should include sender and fuel pressure sensor). And a couple notes. If you have around 100K or more miles then DEFINITELY change the entire assembly. It beats having to do all the work again in the near future. No matter what route you go be sure to replace the fuel pump tank gasket.

When pumping gas the pump constantly disengages as if the tank were full - it doesn't matter which station or pump. It goes off about 10 times while filling the tank. I've taken it to the dealer...

Back pressure is going into the gas pump handle. If you havent already done so, when filling your car play around with putting the gas pump handle tube in at a different angle. My car often gives me the shits doing this too. I find that if I turn the handle so that it is at right angles or even completely upside down with the tube pointing in a different direction within the fuel intake on my car it works fine. Can be frustrating though particularly on high flow pumps.

2008 Wrangler--whenever, and no matter how slowly I pump, I fill up the gas tank, I get blowback of fuel from the tank. If it happens at full speed pumping, it's enough to leave a puddle on the ground. ...

Yes it happens to others. No one seems to have a fix other than don't fill up. I have gotten to where I can pretty accurately estimate how many gallons I need to fill it, and then cut it off before that point.

The fuel guage on my 2004 Chrysler Pacifica jumps around

This is a simple service fix. It's a glitch in the computer system. Take it to the dealer and there is some sort of code they can enter to "update" the car's computer.
Mine does it occasionaly, it annoying, but not harmful.
I've heard of some that will act up for a while, then stop, while others, have acted up and them the fuel gauge stays on empty.
Talk to the dealer.

Won't take gaskeeps clicking off no matter where you position the nozzle

If your fuel nozzle keeps clicking off while trying to fuel your gas tank then you may have a problem with your fuel tank pressurizing and releasing the pressure. Meaning your tank vent valve may be bad or stuck closed. this is part of your cars emission system and the only real way to check it is have someone with a scanner access the system on your car and check it. A technician can activate the different valves and switches in the system, check it for codes or other problems using a scanner with the proper software for your vehicle. Something you may can do yourself is just look at the hoses going to and from your fuel tank ensuring none are disconnected, collapsed or kinked, this could cause problems also. Hope that helps.

Can't fill the gas tank on 98 Toyota Camry

I have a 2000 camry that I just fixed today. there is a vent tube and valve on the carbon canister that is located just behind the gas tank and above the cross member. this vent tube will get plugged up by ( of all things ) spiders, dirt daubers, and I even had a mouse pack the tube with dog food. Just remove the tube and the valve from the canister and clean them out. You will now be able to fill your gas tank again.

The fule tank vent tube is blocked/clogged. It's the little hole next to the filler hose that invites spiders that clog it up. Blow out the tube and it fixes the problem.
