I had a misfire on #3, so I changed the plugs and wires. I had to use an insert on 5 of the plugs. Drove it for 4000 miles, now I have misfires in 2, 4, 6, 7, and 8. It died on me and will not start. It backfires when I try to start it. Could this be a coil pack or some sensor problem?

I would start with a compression test.

I did a compression check and got no compression in any cylinder. Also My new plugs on 2, 4, 7, had the elecrode burned off. Not sure where to go now
