P0303 misfire cylinder #3
P0455 evap leak monitor large leak detected

How's the plug on #3 and the wire?

It could be a rotted fuel filler, it's a common problem. Get someone to smoke test the system for the leak.

 

new plug new wire all tune up double checked connection all good new fuel pump ill check fuel filter

 

Large leak sounds like back of the truck. One of the two 5/8 lines at the charcoal can, the 3/8 line at the charcoal can, or the fuel filler neck/filler neck vent tube.

 

checked and replaced evap hoses but ill check neck filler
