I have a 1991 Integra and fro some reason im getting no power in my car I thought it was my battery so i took it to get charged but still as i turn my key no light turn on or anything...

 

there is a little black fuse in the fuse box under the hood,check it.did you, by any chance,hook the battery up backwards?

if that doesnt work,try replacing the main relay under the dash.

 

......didnt see any black fuse?... and no didnt backwards the battery

 

The main relay, [PGM-FI Main Relay] has nothing to do with batt. power.

If you get no power at all, no head lights, no dome light, no horn, and no brake lights, [all constant powers, ign. does not have to be on] then it is most likely a grounding problem, check your main grounds, batt. post and cable clamp, batt. to chassis ground, [under batt. "box"] and chassis to engine ground, [the batt. to chassis and chassis to engine ground is all one cable, do not just eyeball the connections, remove/undo them clean both contact surfaces and reconnect, making sure the connections are tight but do not over-tighten. 94
