I was driving down the road at about 20 or so when my jeep started sputtering and went dead. I started it back up and after giving it gas it kicked on for a few seconds then died again. I was told that it may be a fuel pump but I just checked the fuel pump relay and it works. I checked to make sure its getting power and I hear the buzzing from it so it's working. I checked the rail and it is getting pressure. So all signs are pointing its not the fuel pump. I had even put its a full tank of gas in it a couple of days before it went out. Everything else seems to be working properly as far as the electrical parts and the spark plugs all look good visually. I was told that it may be my coil though and I have no idea how to diagnose that.
The only thing that could have messed up my jeep is that I went over a really shitty speed bump that knocked my jeep a good bit but nothing it hasn't done before. I'm worried it may have knocked something loose but I haven't found anything that looks like it as of yet.
