Checked timing
Changed spark plugs
My turbo timer shows the battery voltage and it shows up at 8-9 when trying to start and 12v when on idle

Your battery is dead, or your alternator is not working. On idle you should get something like 14v.
Also your battery should be at ~12,5v by itself.

When cranking the volts will drop temporarily, get a multimeter on the battery, look for between 11.8-12.6v, then with the engine at idle you should see about 13.4-14.4v.
If all is fine there, check your coolant temp sensor

Check your glow plugs haha.. No as AdamB says is rite, possible altanator, battery,fan belt, bad earth.. It could be a number of things but hopfully its something small

HAHA i thought the same thing

As above your battery voltage should be abit over 12volts and about 14 on idle and shouldnt drop much if you turn a few electrics on like headlights and rear demister.

Seeing 12 volts on idle tells me your alternator isn't charging the battery properly.
