CAR SOMETIMES WONT START

1996 Nissan 200SX • Automatic •

My 1996 nissan 200 sx sometimes wont start, sometimes it does. I have to sit there turning the key, waiting, and retrying until eventually it starts. The problem seems to be getting worst and I have to sit there longer until it will start. Sometimes I can hear a rapid ticking/buzzing sound when I turn the key but it wont start. Im afraid eventually it will stop starting altogether. Battery? Alternator? Starter? Help pls.

Next time it refuses to start don't wait for it to make up its mind-do below immediately to determine if its fuel or spark problem

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if okay-check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,cap and rotor,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing
