According to the books, all of Harry’s grandparents were deceased by the time Voldemort attempted to kill him, which is of course why he was shuffled off to the Dursleys’. He came from a prominent pureblood wizarding family that refused to join the Death Eaters, which would make them a natural target.
The Potters: Harry’s parents James and Lily were killed by Lord Voldemort. His grandparents, Fleamont and Euphemia, passed away after James’ marriage to Lily Evans but before Harry was born.  The Evans: Harry lived with his mother’s sister, Petunia, and her husband Vernon Dursley and son Dudley.
Because both sets of grandparents had passed away before Harry was born. Petunia Dursley, the sister of Lily Potter, was Harry’s only living relative. Harry could not go to his grandparents because he HAD no living grandparents. They had all passed away already at the time his parents died.
At some point between 1979 and 1980, James’ parents died of Dragon Pox, and he inherited the vast Potter family fortune from them, which enabled him to comfortably support his family without the need for a paying job. James also used his wealth to support Remus, who was unemployable due to his status as a werewolf.
