‘05 Chevrolet Cavalier died

Was driving my 05 chevy cavalier and it died an never started after a new battery and a new starter and a new alternator and still wont start

Won’t crank? Or cranks and won’t start? Any OBD2 codes? Is there spark? Is there fuel pressure?

So why were the battery, starter and alternator changed? Seems your mechanic was just guessing at the reason it didn’t start. That is a very expensive way to fix a car!

Answer the questions I posted and we’ll see if we can help.
