I have a new body 2007 5.3 chevy truck. i started it last night and then the ses light came on and now today my truck won't start it won't make any nosies or anything the lights and gauges come on but don't cycle like normal so i have no idea what it could be the battery it good the starter is good so any help would be great thanks

 

My bosses 2003 did the same thing. He swapped the starter relay with another under the hood and it worked a few times but he ended up having to put a new starter in. No issues after that.
