My 2000 XJ was throwing codes for a major evap leak. After visually checking everything and coming up empty it turned out that the pump was bad. I took it to a mechanic because I wanted it verified before wasting money and he did the test and found no leaks. The cost of the whole job was under $200, could have done it myself if I had more confidence.
