2003 sable wont crank

car had some issues with all dashlights coming on and then not cranking after being turned off and attempting to start it back up. it would just click. battery has been replaced as well as a brand new solenold being installed. started having same issues again. had battery tested and it was ok. car would randomly not crank but after setting overnight it would start. not it wont start at all unless jumped. just clicks. cars in the shop now after being at merchants 3 times before for the same issue. any ideas?! im at my wits end already and my wallets growing thin!

Make sure all battery connections are clean and secure. Make sure connections at the starter and solenoid are clean and secure.

Starter may be bad. Worn bushings in the starter can cause it to lock up, require an extra jolt from jumping to turn.
