I have a problem starting my 1993 Nissan Sentra. I Just bought a new battery and replaced the water pump. I also replaced the oil filter, spark plugs,and spark plug wires as well as the oil. I can only start the car if I do it with jumping cables hooking it to another car. I Unplugged the battery while the car was on and it did not die; therefore, I know the alternator is working well.
There is something I just noticed recently if the car is on and I turn the light on, the car dies. What can the problem be? The car passed the smoke test last year without any problems.
Any suggestions, I will appreciate it
thanks,
Juan
