How do you use a Launch CRP123 scanner tool to set timing on 1998 5.7 Vortec?

That model year uses a knock sensor - it's supposed to adjust timing automatically. That being said, from what I can read about the scan tool in question, it's just a code reader, and doesn't have two way functionality aside from being able to clear DTCs. For such functions, you'd want a scan tool like mine - I have a Snap-On Modis. Feel free to go see for yourself how much one of those costs.

How do you set timing on a 4.3 Chevy s10 pickup?
It all depends on what year the truck is. If it is the older version with the round distributer cap, you need a timing light. Connect the timing light to the number 1 cylinder, which is the front one on the drivers side. next you have to put the computer in base timing mode. To do this you need to locate the timing connector, which is usually located in the passenger side under the carpet ,below the hvac unit. Unplug the connector and start the engine, then shine the timing light on the timing marks and loosen the distributor and turn it unill the marks line up .Then tighten the distributor, and reconnect the connector. If it has the flat cap , the timing is set with a scanner .

96 Chevy 4x4 12 ton 5.7 vortec timing reset?
There is no adjustment on the timing, It is controled by the computer. If you did not have the distributor out then there is no reason to worry about the timing, Unless the check engine light is on and you had it scanned with a engine scanner and it said that the timing was off. You will then need to hook scanner up to engine and go into the timing mode and move the distributor until the light goes out. Then tighten dist. and the computer will do the rest.

How do you time a 350 Vortec Chevy?
There should be a sticker on the fan shroud telling you which wire to disconnect. On the older tbi motors it was tan with a black stripe i believe. Disconnect this wire, the loosen the dist. bolt and check the timing with a timing gun. Rotate the dist. until you get the desired timing then tighten the dist. bolt and connect the tan wire. On a vortec engine you have to have a engine scanner to adjust the timing. But if there is no check engine light on then the timing is correct all ready. It is controled by the computor, There is no ajustment needed.
