Chevy S10 in 2001 didn't have a 2.0L engine. They had a 2.2L engine and it has a (DIS) distributorless ignition system. There is no timing to set.
If you have the 3.8L engine, ignition timing is controlled by the computer and cannot be altered without making changes to the computer. If you have the 3.1L engine, which has a distributor, you can set the timing as you would on any engine with a distributor.
