No power to my injectors!

If this is like most other car brands, the first thing you must do is check for spark. If that is missing, it is likely 12 volts for the injectors and ignition coil(s) comes from the same source, and that relay is not being turned on. If that is the case, start by checking the wiring for the crankshaft position sensor to see if a mouse made a meal of it.

Check for 12 volts on fuse # 16B, a 30 amp, in the left side of the instrument panel. That feeds the injectors, but it also feeds the "ignition discharge module". Voltage for that fuse comes from the main relay, and that one is fed from fuse # 2, a 60 amp maxi-fuse on the right side of the engine compartment.

If you have spark, all that has to be working. That leaves splices buried in the harness. It seems very unlikely all four injectors would be missing their 12 volt supplies while the ignition system still works.

Let me know where you have 12 volts, then I'll check back on the diagram to see where to go next. By the way, that 12 volts at the injectors is on the green / red wires.

Dandy. All four green / red wires are spliced together in the harness. Assuming your probe was making good contact with the terminals, so your readings are to be believed, pull the tape off the harness and look for a splice that's green with corrosion.

Nope. If your Christmas tree lights don't work, you don't go over to your neighbor's house to diagnose his lights. When there is a problem with the red / green wire, you don't go looking for a problem with other wires. If you have 12 volts at the splice, those wires only run a few inches to each of the injectors. The problem has to be a broken wire right next to where it is crimped to a terminal in the connector or your meter probe isn't making good contact. At this point it is acceptable to unplug a connector from an injector, then touch your meter probe to the terminal on that side. If you find 12 volts that way, your meter probe wasn't making contact. I've been in tv repair since the early '70s, and as an "expert", I can't tell you how many times I've gone in the wrong direction after getting an incorrect meter reading.

If you do not find 12 volts that way, tug gently on the red / green wire. If it acts like a rubber band, the wire is broken inside the insulation. That is not too uncommon, but it would be very unusual to happen to multiple wires at the same time unless the car was previously flood-damaged.

There's a red / green wire at each injector that supplies the 12 volts. I'd have to dig out the diagram again to know for sure, but that 12 volts will be there either with the ignition switch on or only during engine rotation, meaning cranking or running. The other wire for each injector gets grounded by the Engine Computer only when it wants to fire it. When the injector is off, that control circuit is open, so the 12 volts from the red / green wire will go through the injector and be seen on the other wire. You can't measure the firing with a digital voltmeter because of how they work. You have to use a scanner to view the number of milliseconds listed that the computer is holding the injectors open during each pulse.

You can't measure the voltage on the control wire to determine if the injector is being pulsed on due to the way digital meters take a reading and display it. I have a web page that explains this but I can't find it at the moment. I'll try looking again tomorrow when my laptop battery is charged up.
