I would use my ***** but I don't have much feeling left in that thing from all the dolphin "relations".
Thanks for the help, all.

Have you converted to sequential fuel?
If so, have you performed the test I described (replace all 4 injectors with light bulbs, test each driver/"injector" using the output test mode.
Do you still have the stock 90-93 coils?

Yes
No, it's $100 so I was trying to get around that. I guess it's time to get out my wallet. Listening for the audible clicking noises from each injector is insufficient for a test like this?
No, this is VVT with VVT coils, son.

Is this what I want? I'm not sure which plugs into the EV14 from the pictures and searching is failing me.

Why are you guys focusing on fuel and not the coils? Serious question. The injectors seemed to work normally, audibly in test mode, the coil clearly did not in test mode.

You said it is getting spark. My assumption is if spark is functioning correctly, you're dumping in too much fuel. Even if you can "hear the injectors" who is to say the injector is coming completely closed/getting hung open?
Swapping bad cylinder injector with another and having the problem on the same cylinder would immediately rule the whole fuel thing out. Then you can say without a doubt it's a spark problem.
Or your engine is blown.

I used a spark-plug light to determine that each coil is at least activating the light.
So today I used the multi-meter to determine that each injector is firing in test mode with similar voltage numbers. (The light I bought won't work, so I might have to buy another.) Injector A is the only injector that made a mist of fuel shoot out the spark-plug hole when using test mode, the rest did not but they are clearing squirting fuel. Time to rewire and replace injectors?
