I have a '00 Blazer (same body and engine), and we bought a pump from Advance Auto - been in service for about 2 years now without issues. The only thing I don't buy from these discount auto stores are brake pads and rotors. Seems everything else is fine.

BTW, don't go by the computer saying how many miles you have as it's merely an estimate - it's never dead on!!

Just so you know, even just a little leakdown in pressure will cause troubles. Especially when it's cold out. We were getting somewhere around 50-55 PSI when we noticed troubles. It only lasted about 1 more week then we were pulling out the pump and replacing it. That engine needs something like 63-65 PSI to be in good shape. Good Luck!
