engine wont fire

[corymcrae]

so after i put my new headers on i started my pickup up just fine and let it ran. when i got back to it a few days later it wouldn't start. i discovered my distributor had gotten loose somehow and moved itself all the way to the right, after timing it by just cranking the engine it still wouldn't fire. i traced the plug wires back and everything is where it would be. it pops when i crank it but nothing promising and only on the passenger side of the engine like it wants to start and a couple times it did start but only for around 10 seconds. so i take the plugs out and find a few that were saturated with gas. on the drivers side nothing happens but the plugs get wet. its getting fuel so what could be the problem? do i need a new ballast resistor or coil or possibly a new distributor?
