Did you test for any spark ? Did you test for anything ? Do you hear the fuel pump prime the system when you hit the key ? You should hear a faint whirrr , You can't make assumptions on past performance , things need to be tested .

any codes pulled from the computer? there are stored codes that could provide clues to problems. places like o'reileys or pep boys can do it. maybe AAA too .

If the car was dead when you became involved, the possibility of a cracked head due to overheating. Checking compression on my 2010 lacrosse involved removing the intake manifold but that's what mine turned out to be.
