Not an expert on 1991 systems but in earlier versions the key activates the RSR and then supplies power to the ballast resistor which in turns supplys current to the injectors. Actual grounding takes place in the FI computer(ECC)
You need to work backwards with a test light to find out why the injs. are not powered.
I'm also thinking that swapping RSR's may not be definitive unless you are certain that it functions correctly.



Sorry, I have no manuals on the 1991 so none of what I just said may apply.
