Yes the connection is covered by the boot. I unplugged it to see if I can see the spark. I don’t remember the volts I checked them when i first ran into this problem. And they were all fine.

So... what injector voltage values do you consider to be "fine"?
You should see little-to-no arcing in those coil towers, even with the boot pulled back. Check for a good spark at the plug end of the wires; it should jump a gap of at least 1/2"
Again, I urge you to post pix or videos of what you are seeing/doing.

I’m not completely sure what they read at voltage wise. Me and a friend of mine who is an electronic guru. We looked at stealth 316 for the values and they all read the right volts. It won’t let me upload pics. But, I unplugged the wires that go to the coil pack from the pack and there is an arc at every coil pack but one. It has 3 coil packs.

I can’t see the video
How is my testing not valid. It’s a spark plug test light.
Your testing may be valid, but it is unclear to me what and how you are testing, as well as the test results.
Clearly this is more than just a "one coil won't spark" issue, as the engine would start and run on the other four cylinders if that were the only problem.
If you won't answer questions, stop challenging why we are asking, and post some pix/videos, I will soon give up here too. I am not insisting everything I say is correct or makes sense; but I need to get a clear picture of what is going on to help you.

Let me try and figure out how to upload a picture or a video. I test the plugs with a dummy light. You know, it plugs into the boot of the plug wires? I’m not challenging why y’all are asking in any means possible.
That is the pack that’s not firing

Let's ignore that coil for now. Let's try to find out why it won't run on the other four cylinders.
What make/model spark tester are you using, and how do you have it connected (pictures!). Have you tried just looking for a spark at the plug-end of each plug wire? I just want to know If you can get a 1/2" arc/spark there, and if it is consistent/regular as you crank.
I am focused on ensuring there is spark to the other four cylinders because that is the easiest thing to check. I don't want to head into checking ignition timing or valve operation/timing until I am sure you have spark on at least four cylinders.
Again, you have tried starting-fluid, and no firing (combustion) on any cylinder? I would try that again, but disable fueling by pulling fuses/relays for both the injectors and fuel pump. Pull the plugs and crank it for several seconds to clear any fuel from the cylinders. Then re-install the plugs and try the starting fluid. Point is, to make sure the cylinders are not inop because they are flooded.

I do t know the brand that it was i borrowed it from my brother. And yes I pulled that boot off that my finger is on and no spark. Did the same to the other ones and there is spark. I did do the front three spark plugs and there was some fuel in one of the cylinders. I didn’t dive too far into the rear because of the intake on the back I have to take it off entirely. I did however just pull the ecu
Te video was no good for me. It "played", but was a black screen the entire time. The thumbnail shows a PCB, I presume it is your PCM. I suggest we don't fuss with the PCM for now.
Your are confusing yourself by pulling back the boots at the coils and looking for spark. Ideally, you should not see any spark there when the plug wires are connected. You need to go to the other end (plug end) of the wires to look for spark. Or, remove the plug wires from the coils and insert a small screw or wire into each coil tower such that there is about 1/2" gap between the ends of the screws/wires. A good coil will jump that gap easily.

Okay so I’ll do it the plug way also then. And then I’ll report back to you. It’s my ecu I pulled it out to check it and see if any caps are popped. I’ll recheck the spark tomorrow in the morning. And I’ll give pics
