Ok, every once in awhile my 4 banger 07 Colorado wont start. I'll turn the key and it WILL turn over but wont start. I'll do this a few times with the same results. It turns over like it's not getting any gas. Let it sit for 5-10 minutes. Then finally.....BOOM it starts up. I've tried to recognize some kind of pattern in which I end up getting the truck to start but can't seem to find one. It's not the battery, I have a new one. I'm thinking maybe some kind of relay or a strater problem. Any ideas?
