Please Help!!!! Ok so i went to go get gas...and for the 10th time since this started happening, i put the nozzle in my tank, and i start to pump, and it cuts off, so i pump again, and it overfows my tank, when its on empty, all over my car!!! 
Its SOOOO frustrating and i can't for the life of me figure out why its doing that.
The only way I have found to get around it was looking for a gas staion that had an extremely short nozzle, and slowly pumping. But slowly pumping doesn't help my situation at regular gas stations, it just overfill's slower...
It's been happening for about a month now.

Take the rear splash gaurd off in the left rear quarter and see if the filler neck, that goes from the panel to the tank which should be rubber is rescited in any way. Sqeeeze the hoses and see if there is anything in the hoses. Good way to play practical joke on someone.

Poor Fuel Fill Quality
Problem
Causes
DEFINITION: During the fueling process a continual, occasional or no fuel nozzle shut-off condition has occurred.
Difficult to fill
• Fuel fill limiter vent valve stuck closed
• Evaporative emission (EVAP) canister restricted
• EVAP vent valve stuck closed
• Hose between canister and canister vent solenoid twisted or kinked if applicable
• High fuel temperature
• Fuel filler hose is kinked
• Faulty dispensing nozzle
• Ignition switch ON, vent valve closed
Over fill
• Fill limiter vent valve stuck open or leaking
• Fuel inlet check valve stuck open
Pre-mature shut-off of the fuel dispensing nozzle occurs immediately after engaging dispensing nozzle, tank empty
• Restricted vapor lines or fuel fill pipe
• High fuel temperature
• Inlet check valve at tank stuck closed, fill pipe full of fuel
• Fuel tank full, gage not accurate
Pre-mature shut-off of the fuel dispensing nozzle, more than 1/8 of tank capacity dispensed
• Kinked, pinched or plugged lines in fuel tank vent system
• EVAP vent valve stuck closed or restricted
• EVAP canister restricted
• Fuel limiting vent valve stuck closed or obstruction at top of fuel tank
Fuel Spitback
• Restricted EVAP canister
• High fuel temperature
