Hey folks I need your help. 2000 Buick Lesabre with approximately 210,000 miles I had the fuel pump replaced 3 months ago and yesterday when my grandson turn it off after a short drive it will not start .The fuel pump will not run as if no power is getting to it,I tried different relays to no avail. Any ideas?

Your going to need to check to see if it'* getting power at the fuel pump. Was the fuel pump replaced with a factory part or was it aftermarket? I have had no luck with the aftermarket pumps. I always go AC delco or Delphi on GM vehicles.

2000 may have inspection plate in the trunk for trouble shooting pump, just have to look under carpet
