Question about 1998 Chevrolet S-10 Pickup
That’s what you need to diagnose swapping injectors is the way to go to see if the problem follows injector one to the new cylinder and also can plug a mood light into injector harness to check for injector pulse should flash steadily

I would swop injector 1 with injector 2 and see what happens before changing unneeded items.

Do you have any engines codes like P 0300. Sounds like ignition coils ,check input wires to coils if okay replace both coils.I have seen this few times

Thank you for all the information. I don't see how you made it worse unless the injectors were not installed correctly. If you remove them you are suppose to replace the o-ring on each of them and oil them (the o-rings) before installing them. I would check the air filter and the CAT (for excessive back pressure. Also check the rest of the exhaust for damage. If a pipe is kinked or flattened it would need repair. Also GM's are known for some issues with there e-vap systems. You may want to check it out. The gas cap, charcoal canister, vacuum lines. Well good luck.

You said the the 2 cylinders in the middle has no fire. That will be 2 & 3. It has 2 coil packs. One runs 1 & 4 the other runs 2 & 3. Check the coil pack that runs 2 & 3....The firing order is 1,3,4,2... It runs because it hits,miss,hits,miss....just enough to keep it running....
