GMC Engine light

In Nov 10, the engine light came on, 2001 Sierra 5.3. 1st replaced the gas cap, then a sensor on the front of the engine, then a canister by the gas tank, then the sensor in the gas tank, then some sensor by the engine. Now the light is still on. I have spent almost 2,000 dollars - Mechanics tell me that they have to do what the codes tell them. I'm basically trapped - no way to even choose what I can do. I just have to keep spending money with each new code, The mechanics can not even tell me if the next thing will fix it.
Very, very frustrated.
Is there anything I can do that will tell me what the true problem is?

The code had to do with the evap system p1441 or similar?

After replacing everything, charging over 2,000 dollars they found that the second component they changed had a crack in it. The issue has been solved - the system GMC has designed to find the problems is a very poor design. Mechanic's could not know for sure which component was not working - we just had to keep replacing based on the cheapest to the most expensive(kept getting the same code). Frustrating to deal with. I have enjoyed my GMC but this sure put a damper on it. The process even got the mechanics upset at me because I just wouldn't allow them to keep spending my money without asking lots of questions(which they had no answer to). If the system could have told which part was bad it would have cost me $200 to get it fixed, instead I had to replace 4 other parts that really were not broke.
