Starting issue after spark plug porcelain broke off inside the spark plug hole?

I changed out 2 spark plugs and on one the porcelain broke off inside the spark plug hole, but I tried to start it anyway. It wouldn't start. So I it most of what I could see if the porcelain out replaced the spark plug started vehicle it started but sounded like it was going to shut off, I gave a litter gas and it help for a few sec but sounded the same then it shut off and wouldn't start.I found that a bolt was broken that hold the coil pack onto the spark plug hole. I it a new bolt finally and seen that there rubber seal on the boot of the coil was ripped in 2 spot. Got a new on of them but I had lost a park plug in the time, so I put a used one in that wasn't bad but I want new. Now the vehicle started once and shut off fairly quick only ran about 45 seconds to a minute if that. It won't start now. I'm wondering if the old spark plug, I used is probably the issue or if maybe the camshaft position sensor went out during all that. I did have a code from a code reader that said something with the timing of the camshaft that was like a month ago. I the vehicle only ran long enough once now for service engine to come on and it said something about random misfiring issue. But I deleted the code. I was told if I spray starting fluid and it doesn't start the it's the spark plug if the starting fluid does start it then its something else maybe camshaft sensor or possibly fuel related? Please help with any thoughts or recommendations.
