I have a 96 z with a few basic things done to it exhaust plugs stereo cold air and its acting up. I did some basic mantience one night and when i disconnected the battery to clean the terminals i was putting it back and and bumped a bracket and the positive and got a spark i dont know if this is my problem but i also had removed a alternator bracket to put a new clamp on a line and thats it. It started and ran then it died on me while driveing and my interior lights went out but headlights stayed on. After sitting a while it started and ran then repeated it did this a few times until eventually i pulled it home. Its in my garage and started this morning and ran for about 15sec with a little bouncy idle and now wont start again. Please help.
