My 95 Lebaron Won't Start Possibly Due To Something With The Fuel Pump/relay Hel

Please someone help me. My husband and I have a 95 Chrysler Lebaron we bought recently. We barely only started driving it for a few months before someone punctured a hole in our fuel tank. The person who did it did put JB Weld on it and it seems to be holding up alright, so far. Then one day we were driving it and ran it completely out of gas and then put in 4 gallons of gas into the car and it just wouldn't start after that. We're assuming that it has something to do with either the fuel pump or as my dad says the fuel relay please help if anyone's had this problem before. I don't want to have to buy a completely new fuel pump for no reason if it was just the fuel relay. I just don't have the money like that right now so please help if you can thank you.
