I have my check engine light and check gas cap warning coming on I had the code read and I got the a P0445 code I have tried an aftermarket gas cap and the gas cap off my 2008 silverado and the warnings keep coming. From what I have read it is the evap system problem but where do I start??

Thanks I will try to find it tomorrow, I looked once but I guess not hard enough I am going to check out the condition of the valve and lines and then decided weather to change parts or take it in to have it fixed
Well I changed the purge valve and all the lines I can't find anything wrong but the light is still on, but the check gas cap light only comes on every few starts. Also I am not sure if this is related or not every once and a while it does not like to start you turn the key but it doesn't want to fire, shut it off and back on it fights a bit but it starts, any ideas???
That's what I was afraid of. If the purge valve is new and you're still getting P0445 (are you?), then the fault is probably electrical, either in the wiring or ECM itself. In addition, it must be intermittently failing the EVAP leak test (actually leaking or FTP sensor fault?). As luck would have it, it's really not feasible to work on EVAP problems without a smoke machine and professional level scan tool. It looks like you'll have to take it in for service.
