Turn the key and starter makes a clicking noise and lights on inside flash its not the battery its fully charged and it's got a booster/charger on it. At 1st thought was bad starter got new 1 and still doing same thing wold this be some kinda anti theft system doing this or maybe bad connection some where?

If it doesn't start still and starter is good and fuses under hood are ok then get it scanned it may be an anti theft module problem.

Couldn't quite get to theft deterrent relay to unplug it and check but I could see it clearly and it looks spotless. Iv been thru every fuse box checked all the fuse's and the box's connections and for corrosion it all checked out grounds seam good at this point im bout dun with it got a guy says his brother gots a computer thing to check it. If he shows up and that dosent show or giv aney hints whuts wrong im thinking onley thing left is to scrap it at this point eazyer to scrap it then thro 100$-200$ in parts at it.

I got that vid ill uploade it just cause and post link to it hear later

Even if you look at module you can't tell if it 's the problem or not. It has to be scanned for codes. Then they can tell you what is wrong with it. If you replaced it, it would need programming anyhow and it is probably above your limit for the car. Unplugging it will not let the car start.

Ya I know all that.

When I get it scanned im hoping for somfin along the lines of a rat chewed a few wires along such n such path(i know its not that specific)and I can just hunt them down n patch them up

its a shame tho it works fine other then this stuff hell the inside and trunk look brand new. I miss distributor caps hell of a lot cheaper/eazyer then replacing computers/security systems.
