`00 GMC 4X4 with a 5.7 liter with a starting problem. Sometimes starts
first try and other times not. When it fails to start there ares no
instrument panel lights. The engine still turns over but will not fire.
When the instrument lights work the truck will start. Does this sound like
a computer problem? Ideas please.

No, it sounds like a battery connection problem.
Believe it ot not, corroded terminals will let battery turn over, but
corrosion on the leads off the terminal can and has caused that problem in
three of my friends ani's tahoes.
we had to remove terminal wires and clean with baking soda and water, VERY
hard cleaning and never had a problem after that.

If it was a battery connection it would not crank. I would be looking
at a common ground proble with a ground being shared by ECM and panel
lights.
