Oh great Cadillac gods, I had a random thought in my brain. (Hide save yourself). What if everyone who has a secondary air injection pump that has not failed yet go underneath their ca, take off their splash shield, take off bottom sound barrier cover on the air injection pump, drill a hole in the bottom of the white plastic piece. Let the water drain out. put a piece of duct tape or something to seal the hole back up, put the cover back on and put the splash shield back on. This could become a maintenance idea for after some heavy rains or during the winter season?

Like I said random thought thought I'd ask you guys (bowing)

Water will kill the pump, but the usual cause for water injection is that the pump cover falls off. Some people notice when that happens (you'll hear a turbine noise for less than a minute after the car is started cold), fix it, and the pump is fine. If it isn't noticed, the pump pulls in dust and water and fails.

Unless you drive through standing water while the pump is running, there's no water in the intake hose.

Also, the snorkel air intake hose with silencer cracks at the pump, due to rubber old age and dry rot allowing debris and leaves to get ingested. A new pump is not a bad thing since cars driven short distance cause the pump to cycle more often. I have replaced it on mine.
