Chevrolet Repair: 2002 Chevy 1500 5.3 liter v8, compression gauge, chevy 1500

Question
truck going down road simply shut down ( report as I know of). I arrived batt. was died while there replaced batt. sounding like the starter is free spooling but its not the problem at all pilots on bok are moving sounds like nothing is happening from crank up in motor? please help step farthers truck lol

Answer
This is very vague to pinpoint, but its sounds like there's no compression in the motor. The only thing I can think of is that the timing chain jumped some teeth.  What I would recommend is check all the cylinders with a compression gauge.
If the compression is good then I would check for spark and fuel.
But I think you will find that you've got no compression in a few of the cylinders, by the way that you explained this to me.
Hope this helps,
Tom
