Nah no worries, I don't think it is stupid at all....I agree with the whole one differs from the other...

Just thought I would put my own personal experience out there lol

What condition is the fuel pump in? Leave that as your last checkpoint since it's the one that would be hardest to get to.

dont need to pull it out just do a fuel pressure test... youve got a fuel pressure reg so you should be able to have a look at the gauge on idle and give her a rev.. see if it drops off or goes back to a constant reading

Check the sparks from each of the plug leads with engine running (idling) is easiest.
I've had a stuffed DLI coil before on GZE - failing coils are usually worse under load.

I've done that were u pull the leads off n there all firing that's the problem

did you gap the plugs?

It ended up being the wire for the number 2 injector connector being loose causing it not to pulse thus the missfire,

It took my boss all of 5min to figure it out
