4WD QUESTION FOR A

1988 Dodge Ram

1988 Dodge Ram 150 4WD, 105,000 miles, 318 engine. The 4WD in the truck will not engage. The vacumn pump is brand new and was just replaced before I bought it. There is no air coming out of the hoses. It as if their is no suction for the fork to flip over to 4WD. Any suggestions on where to start looking for a possible problem?
