That happens when 1) You buy cheap pumps… way cheaper than an AC Delco or Delphi and/or 2) Don’t clean the tank of any crud you see in the bottom of the tank when you change the pump. Pumps don’t like crud.

But I got off track… Did you have a question?

Could also be a bad connector or damaged wiring.

Yeah for sure go OEM but the shop said they had two Delcos in row that were bad. Also check wiring, connections, and the relay. The pigtail should be replaced with the pump along with the relay. I’ve bought a few pumps and the last GM car that had a pump problem I called the junk yard to come and get it.
