1995 Firehawk

Greetings, first time posting here. So, a friendly hello to everyone! 😊. We have a 1995 Pontiac Firehawk. I didn’t see a board for Firehawk’s. So apologies if I’m in the wrong place. The car belongs to a family member that no longer drives. So it has been sitting in a garage for a while. I tried to fire it up yesterday. But it wouldn’t start. Tried to jump it, thinking it was the battery. But still it wouldn’t start. So I’m thinking now it’s the fuel. I’m not familiar with any Mechanics in this area. So I’m wondering how difficult it is to drain the fuel in a car like this? I drive a Ram Powerwagon. It’s a lot easier to get to under! Lol 😝 I would appreciate a walk through “how to” if it’s not too much trouble. Many thanks in advance!! 😊😁
