Is there a way to check individual injectors on a SCFI jimmy 97 with a noid light or something to verify that injectors are being pulsed? The only procedure I found is GM's coil test and involves some fancy gadgets. And if the answer to the question is yes, how would I go about doing that on the FI module plug?

You would have to back probe each of the wires at the connector on top of the spider. You would have to remove the top protective cover and then back probe using some thin back probes.
