You do not have turbo injectors. They are pink.
That red one is a 270 cc NA injector. If you can make it to portland again, I will give you one.

As in, have you tried maybe trying to arc the wire against a ground to see if it sparks?
Most cars with coilpacks use a waste-spark design. That means that the coilpack on a 4cyl engine, for example, only has two coils. In this case, the #1 and #3 plugs fire simultaneously, as do the #2 and #4. One of the sparks fires in the power stroke, like it's supposed to. The other fires I think in the exhaust stroke, essentially doing nothing, being 'wasted.'
So I don't think #1 is firing while #3 is not. You changing coilpacks and getting the same result is, to me, further indication of that.
Is the #3 injector stuck open, thus drowning the spark, causing the misfire, and soaking the plug in fuel?
HMMM, I thought 1/2 & 3/4 fired together.

OK, replacing the injector was what I needed. Thanks to Douglas Vincent for kicking down an injector that was not only free, but it was even the correct one!
Rather than fool around pulling the whole fuel rail out, I made a tool for pulling the injectors, out of an old pair of needlenose pliers. Turned it into about a 3 minute job. Car runs great again.
Thanks to all!

That's a nifty fuel injector puller you made for yourself. If I wanted to do the same, what do I do? It looks like you heated up the tip, then bent it. Does it have to be quenched in oil or some liquid after it's bent? And does the metal have to get to a certain color before bending it? Thanks for your help!

No, I didn't bother paying any attention to temper and I didn't quench it at all, just let it cool at room temp. I just heated it up and bent it. The first tip I actually got a little too hot and burned a bit of it away. It was literally about a 5 minute job, including dragging out the torch and lighting it up.
