I think it's got two problems:

The flickering, check the battery ground cable on both ends for corrosion. People tend to overlook the end where it connects to the chassis. Remove that and scrub it clean if it looks dodgy.

...tried to turn it over twice not a thing not even the clicking. then tried it on the 3rd time

I think this is caused by the starter solenoid contacts being worn. You can either replace the starter, or get a kit and replace the contacts. It's not hard to do, and the kit costs a lot less than replacing the whole starter. And you get to keep the OEM starter, which is far better than the aftermarket crap.

If you get a kit, make sure it has the contacts and the plunger, like this pic below. Just search the web for "toyota starter rebuild kit". Here's just one I found on Amazon.
