I have a 1990 Dodge w250 and the smog pump was making a popping sound. I took the belt off and the noise stopped. I am not sure what I am to do. Should I replace the pump? The belt? Or could it be something else?

Actually, the pump is required by law for emission purposes. THe truck will run fine without it, but it should be replaced. If it was making a poping sound, it is bad. I would recommend trying to find one in a savage yard. I question if you find a new one.

Let me know if you have other questions.
