car wont start

[jdms-14]

so i have my s14 running after the new sr20 swap and its running good, tonight i came home and i tried to started and it didnt, im using the miata battery and im starting to think that it might be to small for it and there is something sucking the battery and no, is not the radio bc its off... does anyone have this problem??? or know what is it?
thanks
