The Pontiac Montana minivan has undergone two generations of designs since it began production in 1998. The first generation, from 1998 to 2005, features a 3.4 liter, 6-cylinder engine; the second generation, from 2006-2009, has either a 3.5 liter or 3.9 liter engine, depending on the model. For whichever model Pontiac Montana you own, the process for removing the fuel pump is similar, since the fuel pump in all models has to be accessed by removing the fuel tank.
