Misfire on a 2003 Chevy celta 1.0 L

I have a question about a 2003 Chevy Celta 1.0 L engine. 
The engine has 1 crank sensor but it does not have a cam sensor.
I figured it has a wasted spark system on it because of only 1 crank sensor
Unfortunately I dont have acces to any source of wiring diagrams, the only one I have little acces is to Carmin and  it does not have information about description and operation of the system. 
My snapon verus wont have acces to global obd II, neither does my autel M906, 
The car has according with my snapon compression gauge, all 4 cylinder have same compression, about 120 psi, 
Car only runs on two cylinders, 1 and 4.

1. Can a car show good compression on a gauge, but have compression leak when the engine is running?  
note, When the engine gets warm.  cylinder 2 appear to be running better, but cylinder 3 has no change when I do cylinder drop test by disconnecting injectors.  if disconnected 1 and 4 engine dies, but when its warmed, it only drops because cyl 2 its countribuiting a little. 
2. how would I find out how many transistors there are for the injectors without a wiring diagram?
I have tested fuel injectors with oscilloscope and the graph looks the same in all 4, battery voltage, when its grounded, when its switched and the  pintle hump, in all 4, i dont know if what  Im seeing its graph from the injectors 1 and 4 only, 
2 and 3 have a misfire, and it looks like fuel pressure should keep the car running and it does but only on two cylinders until gets warm. 

Thanks for even reading my questions,  its sad to have some ideas on what to do with a car but not to be able find information about operation. 
An idea would be more than appreciated.  
 

You did not mention if you check for spark on all cylinders or what your oxygen sensors are reading in your pids of your scan tool

right,  i did not mention that,  but i does  have a spark in all 4 cylinders,  I dont have a spark mesuring tool to measure how good it is,  but I can tell that sparks  are the same in 4 cylinders,
I did that by taking plugs out and cranking it over looking fisically the spark plugs tip.  
Coil pack was previously replaced before i got it.  and both are working the same, 
 

1. Can a car show good compression on a gauge, but have compression leak when the engine is running?

Yes.
A compression gauge only shows the maximum pressure that is achieved on compression. This maximum pressure may, or may not, be achieve on every compression stroke. An in-cylinder pressure transducer will allow you to see the real time-pressure within the cylinder, on EVERY stroke. Not just every compression stroke but, every stroke of every 4-stroke cycle.

2. how would I find out how many transistors there are for the injectors without a wiring diagram?

You can use all 4 channels of your scope. One channel per injector. If the 4 injectors fire at 4 different times, you have 4 different drivers.
Or, you could use an Ohm meter to check continuity between the injector control wires.


 

I regret not to buy a in cyl pressure transducer when I could.
anyways
my next step i think it ia going to be check for leak down on cyls 2 and 3.

the injectors test is something I can do, I will do that thank you very much
