So I'm having a problem with the car starting and I have no dashboard light my radio works my lights works my battery is good when I turn my key it does nothing will don't crank or anything been trying to figure it out for a couple weeks now I replaced the stater I don't know what else it couple be I thought it could be a loose ground but I check all of them any suggestions what it could be

 

Maybe the VATS / anti theft system would be my next guess if it is dead at the key but you have power everywhere else

 

I would start by bypassing the VATS relay and see if the starter then spins over (it may not crank as VATS also disables the fuel pump via the ECU). The relay is in the driver kick panel behind the insulation (under the hood pop handle) if still not click at starter or no starter spinning then test voltages at starter. Take the battery to a parts store and have it tested (usually free) and if low have them charge it if it will take a charge.

If Vats relay bypass and fully charged and verified battery doesn't get it there then its either wiring or bad starter.

 

I would look at the starter switch on the steering column. It's about halfway down the length of the column and on the top side. They are designed to be adjustable with slotted screw holes. It might have came out of adjustment. Common problem. You'll need to drop the steering column to be able to get to it. Research "How to change starter switch" on YouTube.
