Need service manual help!!!

as stated it the title I need a factory service manual for a 2003 silverado 2500HD 6.0L.
Can anyone direct me where to download one for free. I found the old thread for the Fbody service manuaI but cant find anything for the 03 2500hd. I need the wiring diagram to help diagnose a "cranks but no spark no start issue"

Thanks
