Question type: Maintenance & Repair

Can't find where to replace the fuel pressure regulator for my 2000 Chevy LS Blazer. I bought the part, as Auto Zone lent me their decorder to find out why the service engine light was coming on. I don't have the book for my Chevy, and a friend who is a back yard mechanic can't find it either. Can someone help me with this? Its do for reg/smog, and I have to get this fixed so I will be legal.

It's part of the Spider injector under the upper intake plenum. However I see 2 things wrong with what's going on. #1 if your problem is in this area it's best to replace the whole injector assembly. #2 there isn't a code for the fuel pressure regulator.

The part # for this is 815-300. I looked at my paperwork and I don't see a code that Autozone gave me.
