starting issue with my 96

Use only GM fuel pumps.

Here is some good news,Carquest did change fuel pump manufactuers and they are the only ones that did.Carquest did away from Airtex and switched to Delphi whom makes GM's fuel pumps.I saw this recently and it says on the box with the Delphi logal in it.
