Engine just shut off while coasting and will not start

It has been a good truck but about 4 months ago my engine light came on and I was told it was my number one and number 6 cylinder rings then today it died while I was going to the store I was barely doing 5 miles an hour and it will not crank like it's getting no fire, I don't know if it's my timing belt or if it is my fuel pump relay on my fuel pump I hear my injectors coming on what do you think?
Oh and I left out the part where it idles rough you have to press the gas really hard to get a lot of gas to get it to go at any speed shakes and vibrates hard while driving have to keep punching the gas pedal to make it level out at any speed then it will just start hard vibrating from motor again been doing it for 4 months repaced relay to fuel pump and oil water levels normal. I'm sure I did a lot of damage to a lot things but I'm wondering what I should start with, would jumped time cause all this?
