A service manual (not a Haynes manual) would probably provide the wiring diagrams complete with color codes, correct? If I measured the resistance of the fuel injector from the connector located by the alternator as you indicated, wouldn't I also be measuring the resistance in the wires? Or will it be quite obvious if the injector is a problem (possible short or open condition)?

Is there any other way to test the injector to determine if it is the faulty component, particularly after removal (maybe apply a voltage across it and look for a reaction?)

I'm no stranger to the IM - I performed a LIM a few months ago. If I remove the fuel rail to access the injector I'm assuming I will have to replace o-rings on all the injectors, correct? I will also need to replace the UI gaskets. Am I missing anything else or is there anything else I should check while I'm down to this point?

AutoZone has a Gp-Sorensen fuel injector:Part Number:800-1087N
Has anyone had any problems with this AM part or should I go OEM or OEM/junkyard?

Thanks again for the troubleshooting assistance.
