After i switch my i pod off, it goes into a self start up for a few secs and thens shuts down, it does this until the battery is drained, the on/off button feels not as clicky has when it was new !!

I would think it's a problem with (CCRM) constant control relay module . This module has relay's inside that control the fuel pump , cooling fans , A/C compressor clutch , PCM - engine computer power relay . And thier are electronics involved , solid state circuity . Google CCRM

I would try a freh AC Adapter as it may well be the cause of your problems!

i had the same model and i found that the spark plug that was shipped with it was rubbish I changed that and it ran fine for a week or so the it seemed to overheat and would not start until it cooled down or flooed its self again had to wait till drained in the end i chucked it away and got a sthil in stead not a single problem with in in years and still the same plug

Try taken the bios battery out for about 30 secs, replace it and then reboot, after post press F8 untill you have a screen pop up with a safe mode option use the arrows keys to navigate to safe mode and press enter. In safe mode goto my conputer c:drive(boot drive) windows. In the windows folder look for a file called prefetch, delete all it contents. Exit out of everything and restart the pc. If same thing happens post back.

HI. I would start by isolating the actual drain.

Here is a procedure I use to isolate a battery drain. Remove the negative battery cable from the battery. Using a 12-volt test light, hook one end to the negative battery post the other end to the negative battery cable you have just disconnected. The test light will glow or "light" if there is a drain. If the "light or glow" is faint, that is probably normal draw for the clock or computer. If the "light or glow" is bright, this will indicate a large drain is present. That should be corrected,asap. Now start removing and replacing the fuses one by one until the light goes out; The one fuse that causes the light to shut off, will be the circuit with the drain. Remember to close the car doors, when testing. If not, the interior doom light will interfere with the results of the test.

Once you have isolated the drain, have it repaired, asap.

gtet it checked have the code reset

The problem seem to involve a number of circuits, I would suspect the Key switch as it supplies power to all affected systems. The dieing on release of the clutch is usually the kickstand safety switch. If the kick stand is not up, and the bike in gear, then when the clutch switch detects release is kills the engine so you don't kill your self.
Check or replace these switches.

Hope this is of some help.

the above memory stick which will turn on but after between 3 to 10 secs it shows either the shut down screen and turns off or just shuts off any way..
then it will just keep starting and turning off untill i pull the battery out or put the key lock on.
ive rechaged my battery but hasnt improved at all.the only way i can get i to act noamaly though ( at least briefly ) is to conect to computer and delete all music stuf and relaod it. but it works fine for a while but just goes back to square one..

any one able to help ??

Have you tried removing and replacing your battery? What about the connections and cord, are they damaged at all?

Hold the Menu and Center Button until the screen goes blank.
you will then see the apple logo and you should be set.
