wiring diagrams?

[Kelhasfun]

I am working on a 05 Neon for a co-worker,
(the long story-after buying their '99 Neon b/c they let some rats/rodents or something out in the country chew their car {trying to get to the animal feed in the car} and chew right through a tranny line and thought they blew the trans. b/c it just wouldn't go no more -their words so we bought it for $450, towed it home and fixed for it $1.18 a piece of hose and filled it with fluid, been running great for a year now) and they are now having the same prob. as mentioned above on their 1yr old car the rats have chewed something else (probably mad about the D-Con that's replaced the food and now the car won't start, it'll try and try but won't turn over. So short story we are looking for a fuel wiring diagram on this car does anyone know where we can get one oh yeah and we pulled these codes:
P0452 Evaporative Emission / Fuel tank pressure sensor low circuit
P0113 Intake Air Temp circuit high
P0499 unidentified
thanx to anyone who might be able to help! they live an hour away and it's their only car but I can't stand to see them go to the stealership and really get ripped off - I'm gonna try to go there to get a diagram to help me find the reason we're not getting fuel. I sprayed carb cleaner and it's starting and running just til it burns off though.
