The dreaded P0441 code

This is my first post on this forum. I'm posting because I read previous posts here and believe that the experts here know the most about this problem.

The code is being set on my grandsons 2001 Celica GTS. Also, whenever he gets gas the engine either will not start without depressing the accelerator pedal, or will start but runs rough, or starts okay but shuts off soon thereafter. All of these symptoms go away after a few minutes.

I've done various tests by referring to my Celica manual, and the official Celica wiring diagram manual. I won't go into details about the tests now though because I found one problem that could be the one causing the code.

On his car the blue headed connector is connected to the VSV for EVAP. From reading prior posts here, and referring to the Celica wiring diagram, this is wrong. The black connector should be connected to the VSV for EVAP. But, when I disconnected the blue, and connected the black, the ABS light started flashing. I don't know what this means. So, before I permanently switch the connectors, I'm trying to find out if someone else has had this occur, and what they did.

not sure if this helps, see if the gas cap is bad.
