When you say: 'the car will not crank', does that mean that the engine will not turn over at all, or does it mean the starter motor causes the engine to turn but not catch?
Check corrosion on terminals, ensure that the proper battery is installed. I'm sure there is a reason why the battery sat for 3 months and the car not driven. Care to share?

when i say ito wont crank.
when the i turn the key there are no noises at all. you don't even hear the starter..
lol 3 months ago, we were having problems witht the battery and were constantly jump starting it, but then the battery finally died from discharging too much. Then we had a family emergency these past 3 months, so we've been using our Nissan Murano. that emergency just got under control ,and we decided to fix it.
the battery was installed correctly because all the dashlights work, alarm works, radio lights etc.

I'm thinking ignition switch. These have been known to go bad and may be the source of your battery drain. I'm going to go out on a limb here and say that there is a write up on www.e38.org.
Okay, I looked at www.e38.org and there is a write-up on replacing the ignition switch. Do a Control F and type in IGNITION SWITCH and this will bring up a write up by Dave Cecil. Hopefully you are handy with tools, as it is not labor intensive but do take your time, if you decide to replace the switch.

well, we finally decided just to tow away the car (flat bed because I still care about that car!) and we have an car import specialist near us. he has all his credentials, and he is much cheaper than the dealer, and he still uses original parts. thank god. but we should be getting a word anytime soon. I'll post up the diagnoses, but you're probably right.

starting problems
What's the latest? I am having the same issues and have to follow sequence. Battery dead from trying to start car (battery needs to be replaced ANYWAY). No crazy electrical issues, they are pretty much the same symptoms as a dead or dying battery. Once battery is replaced, will test load to starter and go from there. Hopefully it is the switch. Car would not start properly, - turn key, delayed start, no clicking. Start got more and more delayed until car would not turn over at all. Sometimes while in start position, car would just start after not turning over, is this a sign of the starter or the ignition switch? Jake, you want to chime in? M. Wong? Anybody??

I had some of the aforementioned glitches (seemed that way) and just needed careful diligent analysis to nail down that my problem was the starter. Battery issues can always cause the glitches to occur and that CAN be a sign of a lot of things electrical. Did dignostic, checked power to the starter (that was the culprit), changed the starter and am now good to go. Turns out my glitches were just the way MY particular starter decided to die.
