Nissan Repair Questions? Ask a Mechanic for Answers ASAP
What leads you to believe you had the cables wrong? You would have experienced a pretty good arc.
Have you drained the gas and put in new gas? I think the fuel filter sounds like a good next step, modern gas in the last few years starts to break down in a matter of a few weeks unless you put gas preserver in it, if it sat for a long time before that you likely have varnish buildup, and maybe even rust particles.
Most of the time whe.n you reverse the cables, you will either blow a fusible link (if you are lucky enough that your car has one) or you will fry a circuit in the ECM. I'd hate to condemn it right away though, so I would check your ground points (battery ground to the body, other wiring grounded to the body or to the engine block) and clean them up before retightening them down.
