I've owned the Downtown Cab Company for quite a while but it hasn't made money for ages.
I did screw up a few calls… One time my car didn't stop as quick as I thought it would and I accidentally ran the passenger down… Things like that have happened on occasion.
Is this the problem? How can I get it making money again? I rather enjoy taking fares myself so I don't have a problem driving the taxis myself if that'll help.

The Wiki doesn't say that accidents such as the ones you've describe can impact whether or not the cab company can generate revenue. I'm not sure how long "ages" is as you said, but it is suppose to produce $2,000 a week (in-game time) for Franklin. There doesn't appear to be anyone else having this issue out on the internet, making it difficult to answer your question.
It has been a while since I've played the game, so I don't remember if you get a notification of some sort when you receive the money. I recommend taking note of how much cash Franklin has on him, and waiting one week (in-game) and see if his cash goes up by $2,000. This will at least prove if you actually are or aren't getting any money from the business.
