removing the battery cable shouldn't have messed anything up, unless you shorted something else out in the process (which is hard to do if you removed the + cable)..


does the car have an aftermarket alarm? I took my car to the body shop a few years back and when they tried to disconnect the battery with the aftermarket alarm on it, it fried one of the relays so the car would turn over but not start- similar to your problem.

could also have broken a fusible link or blocn a fuse on the ECU circuitry.

thanks for the reply,thats one of the 1st things i did check,the car started,but it is flooding out real bad.called a friend who is a nissan svc writer.he thinks it is the mass airflow sensor.i think hes right becse after it started and was idling i shut it off and its not starting again and i am smelling alot of fuel
