Can't put gas in my tank

I have difficulty filling my gas tank in my 1996 Sebring convertable. The pump keeps shutting off as if it is filled. Thought it was a venting problem but my mechanic couldn’t find anything. Need help!

I found this on the web. It was about slow, but it should fix your problem.

There is a system that traps vapors when filling your car with fuel in a carbon canister.
The vapors are directed through a carbon canister, though an open vent valve and then to atmosphere.

Most likely this vent valve has stuck closed and blocking the flow of vapors thus causing your fuel spit back.

I believe in your Sebring this valve is part of the leak detection pump.

Make sure you do not have any pinched hoses as well.
