Thank you for your thoughts. I replaced the vacuum pump probably fifteen years ago, but I probably only have 10,000 miles on it.It shows visual signs of age, but not necessarily wear. The pump I installed would have been the cheapest unit that I could quickly find, because things were tight for me, financially speaking, at the time. Among the spare parts that I keep in the toolbox in my truck is a fresh vacuum pump, vacuum pump pulley, and a fresh belt. I also keep a pulley puller and installer kit in there. So, I should be good to go in the event that a roadside repair becomes necessary. I'm hesitant to use the spare, though, just because they do cost money and I would then want to get a new spare to keep in the truck. That, and the vacuum gauge indicated that it is making sufficient vacuum, and the frequency of the intermittent issue seems to change depending on what I am doing with that electrical plug.

When I get some time, I may try installing my spare vacuum pump and then keeping the old one in the toolbox as a spare. Then, I suppose if the light goes away, that would condemn the old pump.
I did almost everything to get my light out until the pump crapped out on me. I did not even know the pump can cause the light. Then following replacement, no more light.

unfortunately, a good pump is hard to find. Only could find aftermarket. So I feel my days with the pump are still a concern.

Thank you for the information. When I get some time to work on this, I will give it a try. I guess I already have the replacement pump, so it is worth a shot.
