So my R32 was sitting there doing nothing for about 2 months while i was away. I got back changed the oil and now it wont start, it turns over but no starting ? Any help would be appreciated. Never had this problem before.

Only 3 things needed for the car to start, fuel, air and spark so it's one of those.

Air is pretty straightforward and I would even say difficult to have something wrong going on there. But maybe a faulty air flow meter or loose wiring loom. Try unplugging the AFM wire and plugging back in again in case the contacts have oxidized a bit.

Fuel can usually be figured out quickly by listening for the fuel pump prime when you switch the ignition on before cranking over. If no fuel pump noise, then check the fuel pump/relay etc.

Spark is a bit more difficult to test on Skylines (very easy on old cars with normal leads), but there are plenty of forum threads on how to do it.

Most likely it's the battery though especially after 2 months. It can have enough charge to turn the engine over at seemingly normal speeds but not have enough juice for the spark, so just listening for slow cranking does not always work when diagnosing the battery. Try jump starting it or charging the battery for a few hours and try again. If the battery's stuffed though, charging won't help.

Lead acid batteries die fairly quickly when they are sitting around not being drained or charged, that's why many motorcycle batteries have no fluid in them when you buy them, and you fill it up after you buy it.

Just replace the battery first. 2 months is enough for a battery to die.
