What Happened
The Delphi fuel pressure regulator in your vehicle helps control the fuel flow to your engine. Unfortunately, some of these regulators can leak fuel at an unusually high rate, which could cause problems.
Risk if Unfixed
If the regulator leaks, fuel could enter your intake manifold and cause a backfire. This could lead to a potentially serious situation: the intake manifold could rupture, which could pull out a fuel injector and cause a fuel leak and possible fire.
Free Fix
Your dealership will replace the faulty fuel pressure regulator with a new one designed to prevent leaks. This repair is free, and you should schedule it as soon as you receive your notice, which will be mailed in phased batches starting from June 30, 2004, and September 30, 2004.

Original — What Happened
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH 3800 V6 (L36) ENGINES AND CERTAIN DELPHI FUEL PRESSURE REGULATORS, THE REGULATORS HAVE A MUCH HIGHER THAN USUAL RATE OF FUEL LEAKS. A LEAK CAN ALLOW FUEL TO ENTER THE INTAKE MANIFOLD THROUGH A VACUUM LINE. IF THE ENGINE DOES NOT START WHEN CRANKED, THE FUEL FROM THE LEAKING REGULATOR AND A MISTIMED SPARK CAN CAUSE A BACKFIRE.
Original — Risk if Unfixed
THE BACKFIRE CAN RUPTURE THE INTAKE MANIFOLD. THE RUPTURE OF THE INTAKE MANIFOLD CAN DISPLACE A FUEL LINE, PULLING AN INJECTOR OUT OF PLACE, AND CAUSING A FUEL LEAK AND POSSIBLE FIRE.
