My sister has a 1999 Saturn station wagon. Check engine light came on, they brought it to a mechanic and they ran diagnostics, said it was the oxygen sensor, so replaced it. They had the car back a few days, got home from work last night, went to go out 20 minutes later and the car won’t start. Could it be a related problem to the repair?
G-man: She said the lights and radio come on when they turn the key, and that is all.
