My check engine light is on, the scanner reads code 1401, means some kind of vacuum or pressure loss. When I fill up with gas, the gas pump pops as if my tank is full, sometimes while driving ill loose power and it will putt putt until it gets enough gas to take off again. I have seen other posts like this and it seems they solved their problems. How can I? What parts do I need?

I looked up that code it says diagnostic module tank leakage malfunction. From the gas pump turning off like the the tank is full sounds like the vent solenoid is sticking shut. Also for the code says no testing info available from the manu factor. Let me o some checking.

There is usually the vent hose and sometimes the vent solenoid right along side the fuel filler neck. Unless something was jambed down in the filler neck restricting the flow of fuel. But that wouldn't set a code.
