Question about 2002 Buick LeSabre
Where is it leaking? If its at the fuel rail fuel pressure regulator you may need a new regulator if leaking on the metal part. If its leaking at the rail side its just the "O" ring. Relieve fuel pressure(push in valve under plastic cap right side beside alternator on rail. Remove the torx screw holding regulator bracket. Pry out and replace "O" ring, reassemble. If its not the regulator it may be a fuel injector, you need to remove the fuel rail and replace both the upper and lower injector "O" rings. This however needs the intake manifold removed to repair.

Hello Sandy. This is a dangerous problem that will result in a terrifying engine fire if you continue to drive. Please call a repair shop as soon as possible and tell them what is going on. You may have to have the car put on a flat bed truck to get it to a repair shop safely. Joe
