One problem related to fuel injection has been reported for the 1998 Buick Park Avenue. The most recently reported issues are listed below.
Fuel pressure regulator: the fuel pressure regulator went out on my 1998 Buick Park Avenue 3800 v6 and I had it replaced on 8-19-03 at a cost of $142. 79. It has come to my attention that Buick has now issued a recall on the Buick Park Avenue (NHTSA campaign #03v473000) for fuel pressure regulators and Buick has informed me that my Park Avenue is not part of this recall. I believe that my car is involved with this problem since I have had the exact problem that Buick is now involved in. I believe that if my car is involved that Buick should be held responsible for my repair and the cost that I have incurred. I have documents to support the fact that the part was replaced and I paid for the repair.
