gas tank presurre pump?
 

I got the check engine light go on three times, taken to dealer and was reset each time. The dealer said each time that the code
was for evaporative fuel emmisions and that I need to bring the car in to replace a pump that presurrerises the gas tank.
This sounds strange to me also this pump is located above my exuast system so they need the car for two days in order to replace it. anybody got any info on this? Thanx.

Have they just tried new gas cap yet? And did they reflash the ECU with the newest release?

No new gas cap or reflash
