I have a older gas engine gator. We ran it out of gas and I couldn’t get it to start after refueling. I thought maybe the fuel pump went out so I replaced it. I also replaced the fuel filter and plugs. It now will start and run about 5-10 seconds and then cut off. I’m getting plenty of spark and fuel I just can’t figure out why it’s cutting off. Before running out of gas it ran great. Any ideas would be greatly appreciated.
