Starting issue

I'm having problems starting my 2010 SS. I had the battery replaced a month ago and checked the connection on the starter and everything was good. This problem just started about a week ago, they're 56000 mi on the car. Upon starting the car sometimes it just clicks and won't turn over at all, sometimes it takes a few turn overs to start, and other times it fires right up. It took me like 5 minutes to try and get it started this morning, it just kept turning over acting like it was going to start then die. Upon turning it over I get a CEL for oil pressure sensor and multiple random misfires, but once the car is started and running the CEL goes right away and runs fine, oil pressure reads good as well. For the record I change the oil every 3k with Mobil 1 extended performance, just changed it 3 days ago. I have no idea what is going on.

mine did something like that yesterday. It did it on a warm start though. I turned the key and it seemed like the engine wanted to turn over but didn't. Then I heard a chime and the DIC came on with a traction control light. When I let go of the key the car started the traction control light went away. I looked at a few threads and some where saying that the starter may be heat soaked with roughly the same modification or long tubes and cam.

This can happen anytime of the day and has progressively gotten worse

UPDATE: I have an elite catch can that utilizes a stud on the front of the block for mounting, there is a ground on that same stud, I adjusted the ground and re tightened the catch can, car started 5 times in a row perfectly, fingers crossed.

The black cable on the right front of the cylinder head is the main ground. If it is loose you will have all kinds of issues.
