    Opened this thread a little late. I had this issue in my 03. A few dealers checked it out couldn't find the problem. Local mechanic ran electrical tests to find the short, turns out a dime got in the lighter slot since i keep my change in the ashtray. I ran out and bought the male piece to the car lighter after that. Problem solved. Running the computer diag didn't help one bit.

    If the starter gets hot....would/could it become faulty?

    Interesting. I just posted my experience in the other 03 wont start thread and found this one.

    Out of curiosity, did this condition also kill your battery at times? I replaced the starter on my truck and the problem never reoccurred. I was thinking a short in the starter or solenoid since I was also killing batteries.
