So my 2009 Silverado 4.8l has started doing this thing in the last 6 weeks where it will crank over once and not start. I turn the key off then crank it again and it will fire right up like nothing is wrong. Truck is running great. But this only happens once in a blue moon. It's not a consistent thing. The truck is a 2009 and has only 60,000 miles and just had new plugs and wires installed. Anyone have this issue as well?

Is it just when the engine is cold or does it also do it when warmed up? What does it do or sound like when you try to turn it over? Fast cranking sound...or labored?

Possible fuel pump issue. May need to check the pressure to confirm.
