Hard to start

I did a cold and hot compression test, but I don't think my tester is any good. I got around 40-50psi on both the cold and hot compression tests, but the car started tonight and I don't think it would even run if it was that low on compression.

When I took the plugs out, THAT is when I noticed a problem. And I feel like an idiot for not thinking of it before. I don't remember when I put these plugs in but they were toast! Here are the pics...
Front Trailing...

Front Leading...

Rear Trailing...

Rear Leading...

As you can probably tell, the front leading was the worst one. All of them were worn down to a point but that one was worn down about half way. After I swapped the new plugs in, I didn't have as much of a problem starting it, albeit it wasn't as easy as it should have been.

I started it again after it was warm, after warming it up for the hot compression test, and as when it was cold, it started, but still not a normal startup. So after that I swapped in a different leading coil, but there wasn't any noticeable change.

That's all I did for the night. I will continue to check and try other things.
