One problem related to fuel injection rail has been reported for the 1997 Chevrolet Lumina. The most recently reported issues are listed below.
I noticed the smell of gasoline. Initial searches for the source of the leak were unsuccessful, but after1 - 2 weeks it got worse and I was able to find it easily. The pressure regulator was leaking. I checked for a related recall and found that universal pressure regulators (upr's) produced after 1/9/07 had been recalled, but mine, I believe, is the original equipment pressure regulator. Nevertheless, it may have a design defect. The car has about 161,000 miles on it. The dealer indicated that failure of a part with that many miles on it would not be subject to a recall, even though it is a safety-related failure. I sought out the NHTSA site to try to find out if that is the case, or not. The "incident date" noted below is the date I found the leak. No damage was done, and there were no injuries.
