No crank no start?

Car won't crank or start there's power to solenoid and to dash with key turned on but when I turn to start car the brake indicator light on dash lights up and I get a ding sound from the dash at the same time but no they sound or indicators of anything else . There's the same voltage getting to solenoid as the battery output, but car still won't start. Sometimes it will start up and run okay for a little bit but then chokes out and shuts off like it isn't getting any fuel or air but most of the time it just plain will not do anything but the dash lights and interior and exterior lights including the head and tail lights all work and I have been working on this car for two months now but myself with very minimal auto mechanic know how being self-taught because I can't get anyone to help me work on it and can't afford the repairs or a different car. So, I'm really kind of stuck between a rock (AKA my POS car) and a hard place (AKAbroke) one might say, lol.
