It's hard to chase an issue when it is posted in two places.
It looks like the "mechanics" you've sent it to aren't very good at fixing this vehicle. Swapping all of those parts is really expensive and probably unnecessary. A good mechanic wouldn't leave you with a non-starting car when it arrived running.
At this point it would be useful for us to know more about the vehicle:
the "rubber" in the electrical connector is a seal against moisture... You might have to replace them if they are swelled... Pull the rubber OFF and install as a TEST.. You need the actual CODE you are getting and the MOTOR SIZE to get a little more response.. Bad electrical connections can cause the same problems you have related to COILS and INJECTORS.
