2001 Pontiac Grand Am Nuts in Torrington

Engine Mechanical problem
2001 Pontiac Grand Am 6 cyl Two Wheel Drive 75000 miles

My mothers car starts sometimes and others not. It turns over but wont start we pulled the codes and replaced everything but a couple days later it does the same thing. We have replaced fuel pump rely and all fuses and total tune up and still wont start. Checked the fuel pump and it works but she will go somewhere and have to call a tow truck to get home.
