Can you please define 'no chance of it starting'.
1. Is it that the starter spins the engine too slowly?
2. if so take all plugs out & see how fast the engine spins then..
Whilst they are out check that you still have a spark by grounding 1 of the plugs to a bolt on the engine?
Recharge the battery before you do this & do not spin the engine for longer than 15 secs approx.
Next thing to try if it spins over at roughly the correct speed!
after test 2 ARE THE PLUGS
Are you engaging the COLD START before starting?
You should here a click on the engine when turning it on?
Remember, if you have corrosion in 1 area you may have it elsewhere as well.
Hope this helps.
