I really need some help dont know where to start! This morning on my way to work my engine lite came on about a minute later at a stop sign she started to idle rough and the died. I tried to restart but no luck just cranked dosnt sound like its getting fuel. The two codes are P0442 and PO455 medium and large evap leak. Would the cause the computer to cut the fuel it dosnt seem like it would or should i be looking at the fuel pump?Hope someone can help
