If you've truly lost faith in the founders and business -- which you have -- you should leave now & cut your losses. It's not going to work out, regardless of salary.
As for how to make money after you leave -- get a job or find consulting work. Then jump back into starting a business when you're ready again.
I'm starting a cloud company in Nairobi if you want to do something totally crazy ....
Talk to the people you meet and a new startup will come your way before that year's out.
Since you already are doing consulting on the side, i think you may be able to squeeze 3 months in on trying to get funding, just make every action Fast, Focused and Fundamental to your objectives. Godspeed!
If you're out of money it might be hard to pull this off as I've heard seeking funding is a full time job (or two, as your cofounders have shown) so the product has to be mostly good to go (for at least the time being) if that's going to work.
Using the product you already built with company funds is almost definitely off limits (IANL), so I'm not quite sure how that strategy could be feasible.
