Alright guys the SES light recently came on. I scanned it and it said P0440 which is an EVAP code. I did the basic thing first i tightened my gas cap and deleted the code. The code came back. Here's a little background...I have a 1999 gtp with an '02 engine. I put in a new fuel pump maybe 100 miles before I swapped engines. The car runs great I just need to fix this problem. Also right before i seen the code for the first time I was getting gas and put 11 gallons in and the gauge read half a tank. Any ideas?
