Hi, I am Mike, welcome. I'm reviewing your question.
Turn all of the spark plugs out 1-2 turns and relieve the compression and try again.
You might have a piston partially seized or something else mechanical.
I assume you want to find out what.
First of all, remove the spark plugs and check if anything at all is on any of them such as coolant, motor oil, metal shavings or even if any are damaged like the piston hit one.
Why just 5?
Could be. next you should probably remove the valve cover and see if anything obvious is broken.
What about the valve cover, did you remove that yet and if s, anything under it broken?
have you removed the valve cover yet?
If not, do you need instructions on how to do so?
ok. dont forget to rate me well
