Over the years I've had a problem with the pump shutting off right from the start trying to fuel the car a couple times, but only in hot weather. Just kept trying. Did you try another pump? Don't know if this will help: www.gearchatter.com/viewtopic8926.php

Good to hear dude. Otherwise it must be a vent issue. similar to a coffee mug having a vent hole to pour smoothly. Never really heard of this happening. Let us know what you find.

Could definately be a venting issue. Just for peace of mind, go to your auto parts store and buy a locking gas cap for 10 bucks, its well worth it.

Some cars have a roll-over valve in the filler neck. If you over fill the tank it can cause the valve to get stuck at the top making it hard to pump gas in.

I have had this issue with my 01 ta ever since I installed the blower. I dont think the blower had or has anything to do with it, just a coincidence, I never considered the charcoal canister like you guys mentioned though.

I know for sure there is no foreign material in the filler tube and I have noticed my car is much harder to fill if I leave it running. I seem to be able to fill it at a very slow but steady rate if I leave the car sitting for a minute or so before I stick the nozzel in. If I try to pull the lever up to one of the auto fill setting it will shut off everytime.

OP good luck on your troubleshooting. Dont forget to tell us what the fix is if you track it down.

I've had this problem for a couple of years. Chevy can't figure this out, but something gets stuck down in the neck. What I've done is take a copper wire (like pull some 12 gauge out of some romex), and feed it down the neck to the tank and just fiddle around with it, rotating the wire etc, you will bottom out on something, give it a little push and this valve will open and watch out cuz it may spit on you. I showed this to my mechanic and he can't figure out why it does this. I will tell you this, DO NOT top off your tank, when you fill up and it clicks off, put it back in the pump. I haven't had problems since not topping it off.

I happened to me again this morning. On the fuel line on drivers side theres
a schrader valve with a green cap. I simply poke it to let the air out and viola! I
can pump gas again.

This indicates that the fuel tank is not able to vent... it vents thru the EVAP vent solenoid/valve and thru the charcol canister and out to atmosphere... something is plugging the vent path.

I'm really interested to hear what has caused this. Looking forward to hearing what your solution is.

Good luck, OP!
