Spyder 2G Eclipse Spyder GST Cylinder 1 and 3 not firing. Need Help.

My car: 1998 Mitsubishi Eclipse Spyder GST.
My car is pretty stock, only has the Injen intake and a cheap blow off valve. Yes I know, I should not have the blow off valve venting into the atmosphere, I will be fixing this once I get this misfire resolved.

Please keep in mind through out this entire time I have not had any CEL code come up.

Here is the story:
Back in 2021, after switching to work from home, I stopped driving my 1998 Eclipse Spyder GST. Recently, I decided to get it up and running again to go for a cruise. The fuel pump had seized so I replaced it, got new tires, and got a 2-day permit.

After driving it around for a bit, I took it for emissions, which it passed. However, the technician told me my gas cap failed. Surprisingly, they offered me a replacement at no cost, which I accepted.

The next day, after parking it and renewing my registration online, the car struggled to start and had a misfire when it did start. I was so confused as nothing had changed. My first thought was that the fuel filter might be clogged, as the sock filter on the old fuel pump was basically gone. So, I replaced the fuel filter, but the problem persisted.

Next, I suspected the Cam Angle Sensor, replaced it, but no luck. Thinking the new fuel pump might have failed, I replaced it again, but the car wouldn’t start at all. I then reinstalled the fuel pump I had just removed, and it started, but the misfire remained.

I checked the spark plugs and found that cylinders 1 and 3 were wet, indicating the fuel wasn’t igniting, even though I confirmed they are getting a spark (as you see in the video). I'm not sure why they aren't firing and don't know what else to check at this point. Could someone point me in the right direction please?

Oh I forgot to add that when I go WOT it does not respond at all and that is when you hear the clicking sound in that is on the video. Car does not smoke at all and the spark you see near the coil pack when I turn off the light is usually not there if they are plugged into the spark plugs.

TL;DR:
After replacing the fuel pump, passing emissions car started misfiring the next day. Despite changing the fuel filter, Cam Angle Sensor, and fuel pump again, the misfire persists. Cylinders 1 and 3 aren't firing despite getting a spark.

You at least have a problem at the coil pack. Either the wires or the coil pack itself. Look around and you'll see the grey traces. It should not do that.

Listen to the injectors with a stethoscope or use a noid light to figure out if the injector is firing. If not look at ECU.

@pauleyman Sorry, haven't had a lot of time due to work. But I will be checking all of this on Monday. Also bought a compression tester, so I will also check to see if that may be causing this issue.
Also, may you please clarify what you mean by "Look around and you'll see the grey traces"?

When you get spark arcing out of the boots like that you see grey lines or grey dots somewhere on the boot or wire. Look closely. You could also have a crack on one of the coil towers. Either way that must be fixed. It should never do that.
