I remember a few years back having my check engine light turn on in my 2002 Dodge Ram (3.7 L). I recall that the evap leak code came up and that I bought a new gas cap. Also, I vaguely remember being angry at myself for buying a new gas cap because I discovered the major (and obvious) source of the leak a few days later. The dreaded evap leak code has returned again, and now I can't remember what the source of it was last time (I've already checked the gas cap and that's not it). Anyone have any ideas about what I should check? If not, does anyone know how to build a time machine so that I can go back and ask my younger self how I fixed the problem last time?

Check the hose going to the leak detection pump. Also check the hose going to the purge solinoid. Both are prone to the hoses splitting out around the ends when they get some age to them. Doesn't take much of a leak to throw a code.
I've checked the hoses going to the evap system (mine is on the driver's side), but I didn't notice leaks. If I remember correctly, the leak that I found long ago was under the hood. Where is the purge solenoid? Is that near the evap canister or under the hood?

Just had this issue with my 2007 Caliber.
When I googled the code for tips on how to fix, the answer was: don't replace the gas cap, get to the dealer, you need a dbrIII scanner and a smoke test machine. The tests will have to be done mutiple times to confirm.
In my situation is was the solenoid and the detector that failed. All rubber was good. They also reflashed the computer with updated firmware.
I noticed the improvement in the firmware. The car acts and feels better.
Too many cars, too many parts, too little coin, too little space to work in, too little time left to make it all happen!
Update: down to one ride, still too many parts, a little more jingle in the pocket, gaining space, and it's going to happen this year!
