Issues with supercharged s2k need help!
hey guys so recently my car (2003) with a V2 vortech and Hondata ecu has been misfiring. I assumed it was bad coils or the stock spark plugs that Billman installed when I brought it to him for the first misfire issue that turned out to be a bad coil. So the misfire came back (he gave me an old coil to get me on my way) so I did all new coil packs. Everything was good but the car would kind of hesitate if I pushed it hard in the upper rpms. Recently the car had another misfire and left me stranded. So I just switched to a colder plug and now the car won’t even start. (It wouldn’t stay running with the stock grade spark plugs either). Here is a video, tell me what you think because the car is stuck in my drive way. Thanks !
FYI, the spark plugs Billman put in the car (stock spec) were black toward the lower threads when I pulled them out.

ill have a look... I bought a compression tester but I think it’s the fuel pump for some reason. It whines loud during ignition and I saw a YouTube video where a failed fuel pump gave the same misfire Subaru sound. I think I’ll spray starting fluid in the throttle body to test. Will update tomorrow

The fuel pump should be audible at key on, it should prime for several seconds. Since the video started after key on I couldn't listen for it. I think those plugs look fine btw. Trying different injectors is going to be much simpler than changing the fuel pump IMO. But if you don't have anyone to swap with a pump is cheaper than injectors.

If it doesn't start compression test to check the mechanical components
You can put a spark plug in the coil pack and earth the spark plug body to the engine -ve and turn the engine with the ignition key and watch for a spark. You can see if the plugs are sparking. Check for fuel leaks first.
Maybe do another vid after leaving car a while so we can listen to pump and a have a chance to hear more noises
good luck

Can you post a pic with all electrodes facing same way? 1 and 3 look cleaner may be just the light
