I had a 2000 ZR2 S10 with the 4.3L in it. Same thing happened. The air pump was in a area that would draw in water and cause problems in the pump. Had it replaced and GM even made a kit to put on to help solve the problem. It did not help. fter the 3rd pump, I put a peice of black tape over the check engine light.
