The cylinder compression specification for a 2001 Chevrolet S10 with a 4.3L V6 engine is typically around 120 to 160 psi across all cylinders. For the 2.2L inline-4 engine, the compression should be in a similar range. It's important to ensure that readings are consistent across all cylinders for optimal engine performance. Always consult the vehicle's service manual for precise specifications.
The year and engine size would help but you may have a bent valve or bent pushrod for # 4 cylinder if that is the only cylinder that has 0 for compression.
You can tell a bad valve by doing a compression test.
If its a 4 cylinder its the very front toward radiator, if its a v6 its the very front cylinder on the drivers side
Need more info, is this the 4 cylinder or 6 cylinder engine and which sensor on bank 1.

You need fuel, compression and spark to run, you are missing one of those.
Do a compression test on all the cylinders. You may find a mechanical problem with that dead cylinder.
Hot at idle, 20-30 psi.
The firing order for a 180 degree 4-cylinder engine is 1-3-4-2
Check the compression on the cylinder that's not firing. If you have little or no compression on that cylinder, you need a valve job and depending on the total miles on the engine, you may need a complete engine reuild or replacement. If compression is up, replace sparkplugs, wires and distributor cap and rotor if it has a distributor. GM has been going without a distributor on many engines but probably not an 82 S10.
There are several on that vehicle. They are all threaded into the exhaust system at various points.
It will vary from one engine to the next. What you want to see is that all the cylinders are within 15% of each other.
