My 1974 260z 2+2 was running but now is not, i don't know what the problem is, well i kind of do. I think its my battery but not sure because wheni try and jump the car it does not work it hardly makes a noise, when jumpers are off it make very little noise or no noise at all. What could be the problem?

Thanks

Re: !!Help!! 260z wont run !!Help!!

With all due respect, what does "it does not work it hardly makes a noise" mean? With a quality set of jumper cables properly connected to the battery from another charged battery the car should at least turn over when the key is moved to "start". This means that the starter should cause the engine to rotate. Does it do this? If the engine turns but the car does not start, then the problem is NOT the battery. Taking a wild guess based on the utter lack of information that you have provided, I'd say that there is a chance that the alternator has quit charging, which, in turn, allowed the battery to run down. If it ran all the way down while you were driving it (headlights getting dimmer and dimmer at night, for instance) the car would quit when there was not enough voltage left to support ignition. It could also get so weak while driving it that, once you cut the car off, there was not enough voltage to turn the starter over to restart it. Do not purchase another battery until you determine whether or not the alternator is still charging. Get a good set of jumper cables and try to start the car again.

Agreed with TurboSi. You really haven't provided any info about your symptoms.

IF the car doesn't turn over, the easiest thing to check is the battery. Local auto parts stores will test your battery and even charge it for you for free if the battery is good but run down. If the battery is good, have it charged, then drive the car back to the auto parts store. Have them test the charging system while the car is running. If it's not charging, there's another clue. Then it's time to pull the alternator and have it bench tested. If it's good, it's somewhere else.

There's a good chance you simply have a bad battery and replacing the battery will fix it. Try the things I suggested then post back if you're still having problems.
