Takes a while for the diagnostics to run for P0442 and P0455. An 05 runs the test with the key off.
oh wow didnt know that i guess ill check that after it has sat for a bit, do u think if it comes back if i should take off my bed and find if I have a leak in my fuel lines and EVAP lines to EVAP reservoir??

Look at the EVAP canister really close and make sure it's not cracked from road debris, etc. Check the seal on the cap or have it tested. Make sure to use a GM cap or a GM accessory locking cap...no aftermarkets. Has the fuel tank or sender/pump been removed recently? Possible bad seal on the sender module.
im glad GasGuzzler is the man at anwsering questions lol, no i have never removed any of the fuel system at all they are about 85,000 miles old so maybe a rock cracked my canister can i check from going under my truck?? Thx

Yes, it's the big plastic box with two small hoses and one large pipe. Look at all the black plastic pipes too.
ok ill be under thier today so ill check it all over if the canister seems fine do u think it could be the gas tank leaking??

Could be but that's not really common. The only common gas tank leakers are the 2002+ extended wheel base GMT370 (Trailblazer and clones) that have trouble with the filler neck bung breaking off.
ok just making sure, i looked around the tubes all the way to the inttake but could not find any cracks or leaks, the canister seemed fine but could not see the top area of it.
