Hi,
When you say the fuel injectors are not fully working, what are they actually doing? Are you sure the fuel pressure to the fuel rail is within the manufacturer's specifications?
I attached the wiring schematic for the fuel system, so you have a reference. See pic below.
Have you checked to see if there are any diagnostic trouble codes stored that may point us in the right direction? If not, try it to see if something may help.
This vehicle has an OBD1 system which doesn't require a scanner to retrieve codes. All you need is a short jumper wire or even a paper clip. Follow the directions in this link and let me know if you find anything:

Let me know what you find.
Take care,
Joe
