Is it a boom? If so, then the car is getting too much gas when you start it. Check the fuel injector(s) and the carburator.
If this noise is like a loud ticking at a fast pace, it would be your starter going bad. If the noise is a loud boom/pop sound from the rear of the car, it would possibly be that the exhaust is backfiring..... not sure how to fix that aspect to fix the issue.

If popping sound is coming from carburetor or in take port it could be a broken vavle spring or a flat camshaft lobe.
According to Dr. Eric Dibble, the popping sound you hear isn't actually coming from the water lilies. The sound is produced by fish, often sunfish, feeding off the lilies. The suction action of their mouths cause popping noise.
I would not worry to much about this noise when the motor is cold; engines have clearanaces that come together at operating temperature. If this noise happens when the motor is at operating temperature then you might have a problem.
the most likely cause would be an improperly tensioned serpentine belt
If the 1999 Suburban noise is a sort of loud banging noise, the problem could be that the engine have jumped time. Jumping time would cause the noise and jerking in the engine.
Friction in the transmission system may cause whining noise when a car is accelerating. A poor engine or clutch assembly may cause the excess friction in the transmission system.
