Gravity

So my wife was driving my truck and it died on her. I got it home and looked at it. It will try and start, cranking fine and everything but it just won't start. I went and checked fuel, fuses (big black ones and grey ones confuse me), oil, spark. I have a check engine light on intermittently, the code is p1351. I tried to look it up and got nothing helpful on what it means. Any help would be grateful thanks.
