05 Impala fueling issues. The gas pump handle clicks off so much it takes forever to gas up. I replaced the fuel vent solenoid behind the fender skirt by the filler tube. I blew into the hose thats goes from the solenoid to the canister and pressure builds up in the tank and releases backwards out the tube i blew into. I suck on the tube and can hear air circulating from the filler tube at the gas cap through the tube freely. what else would cause the filling of the tank to e such a battle?

It seems that when filling up, the vapors build and make the pump handle turn off. I tried with the ignition key on and off to test the solenoid to make sure the purge system was open and closed.

At a loss, help please

Sounds like the canister may be clogged...

the tube seems to be correct and not damaged. I was gpoing to start looking at the canister, but wanted input before i get into that mess. No engine lights for the canister though?

How long has it been happening? Evap codes aren't read every start, just after 3 cold to warm runs of the engine and when your tank is between 1/4 and 3/4 full.

No reason to drop the tank, none of those items are attached to the tank. Even if you needed to do something with the pump, there is an access panel in the trunk right behind the back seat.

didnt realize there is an access panel. that will create access to the vapor canister to be removed along with disconnecting vacuum lines? I seen pics but only big enough for the fuel pump/sending unit to pull out?

The access panel will not gain you access to the vapor canister. It is attached to the top left hand side of the fuel tank and the tank will need to be lowered to gain access to it, you may not have to remove it completely but it will need to come down some to get at it.

Check the filler tube, believe it or not; spiders, stinkbugs, ect build "nests" in any crevice they can

ok, i just do not get any MIL and tank between 20-80 full for proper OBDII diagnostics. I have a cable camera for looking into eclosed spaces, ill put it down the filler tube or just take it off. Is it a screen for anti-theft of fuel or is it a metal plate in the filler tube?

Inside of the tank their is a cage with a ball in it to discourage fuel theft right at where the fuel filler neck attaches to the tank.

This happened to me for a while. What i did was get a hand pump and pump gas in from a clean container and then pumped it out, as much as i could. I stopped putting cheap gas in it and been great since then. Just let it run to almost empty after you hand pump the gas in and repeat if necessary. If that doesn't help then your canister might be clogged.
