When you crank, do you a see any extra fuel or a mist of fuel coming out of the affected cylinder ?
Do I need to do this if I hear them opening? I did the test with the fuel pump off.

Cool, but does it matter that this car has sequential fuel? The test tells me everything is working properly on the fuel side. What are your thoughts on the coils and do you have a recommended testing procedure?

Thanks for the help, all.

.
Do you know if they are closing ?

Had a fuel pressure regulator go bad once and all the extra pressure would blow right by the weakest injector putting out the flame.

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?

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.

Wow, such expensive. doge_face.jpg

Ok get just one to test each driver individually, and if need be, get more.

Try swapping the injector with another cylinder to see if the problem follows that specific injector or that injector output.

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.

Do you have a cheapo HF compression gauge?

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.

Then swap coils? If shipping back and fro' weren't a pain in the dick I'd lend you my set of VVT coils.

The wires going to the coil read 2 and 5v, so swapping the coils won't matter, and I"ve already swapped them around with my spares.

So, wiring before the coils. Pinched wire, bad solder/crimp joint, faulty connector.

I can clean and flow your injectors for you if need be.

Dude, I measured with a multi-meter, lol. I guess it's time to chase wire.

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?
