Lumina 3.1L

  • Automatic transmission

This problem could kill people. The fuel pressure regulator fails and the fuel pump sends huge amounts of fuel back through the vacuum hose and into the intake plenum. The intake is located directly above the exhaust pipe. It's a very scary problem. If the fuel regulator fails, the fuel pump in the gas tank sends gasoline under high pressure into the intake plenum. This fuel drips down into the rubber intake hose and pools directly over the exhaust pipe. The engine will continue to run, albeit richly. Meanwhile, the intake plenum fills up with raw gasoline, which drips directly onto the hot exhaust pipe. I am very surprised that people have not died from this problem.
