Starting issue please help
I have a 99 2500 and once I shut the truck off and it sits for like more than 5 mins and when I turn the key it takes like 5-7 seconds to start. It will roll over but just takes like 5 mins to fire up. But if I shut it off and come back before 5 mins it will start right up. And if I get home at night and wake up in the morning to go start it, it will start right up. What could be the culprit??

I'd look at the fuel delivery system first, check fuel pressures for static and running.

SAME THING . check fuel pressure . 60-62 psi key on engine off. engine running need more than 52psi.
if its not the fuel pump the pressure with the engine running should be 57psi in most vehicles I have tested.
if it starts then stalls I would say its around 50 psi.

Sounds like you might have one or more fuel injectors spritzing. Or leaking. When the truck sets the fuel injectors leak gas into the cylinders and is causing a flooded condition. Try cleaning with Seafoam or other injector cleaner. Remove them and clean them. Look for the instructions to test the injectors to see what kind of spray they are shooting,.
