I have a 2001 GTP and had some stalling problems. I swapped out the fuel pump and idle control valve and it runs better but now it is hard to start. It has to crank longer or multiple times but once it starts we seem to run fine.

I had some help swapping the fuel pump and wonder if it is possible that the outside fuel lines on the top of the pump could have gotten swapped and cause this problem. Does anyone know a way to tell other than swapping the lines to see?? If they were swapped what would the symptoms be?

Thanks,
Jerry
