Problems starting?

I am haveing problems starting my car....It starts sometimes and doesn't others. The Starter is not clicking, is seems to be working as normal. Car runs fine when started its just getting her started sometimes.... I have heard numorous things it could be just tring to get a idea from some people who actually have an LS1. When it doesn't start, the starter is turning the engine over, its just not starting could it not be getting fuel at these times, could the coil be bad and not sending enough power to the plugs.....any help is always appriciated.........

Check the alternator. If the car is starting, it's starting via the battery. The alternator keeps it alive

My alternator had a bad connection, was doing same thing yours is. Fixed that connection, it is back to normal again
