2000 Mercury Marquis Repair Question
2000 Grand Marquis no acceleration and no rear lights
If the check engine light is on, have the computer scanned to identify trouble codes. As far as power, make sure the catalytic converter isn't plugged, check fuel pressure, check air filter for blockage...
If all tail lights went out at once, check for a bad body ground. Also, check to make sure the headlight switch is good. Power runs through it for the tail lights too.
