I'd suggest doing what Cruiserfied has suggested as so far everyone who has looked at this vehicle doesn't appear to know what the hell they are talking about, it could all come down to something as simple as a stuffed battery but unless someone professional is inspecting it then you'll only end up ruining your car.

Testing the battery with wire is plain stupidity and one way to kill yourself if there did happen to be enough charge in it :Shocked: a standard household power point is 10 to 15 amp's and can easily kill you...your cars battery is 400+ amp's :whistler:

Never check a battery with wire. Hydrogen & Oxygen gasses are produced when shorting a battery and any spark will cause an explosion, possibly resulting in acid in your eyes and engine bay contamination. Use a voltmeter   :idea:

I only ever did it once when I was about 10 y/o at my Mum and Stepdad's garage.. Melted a big groove in my thumb and index finger (still hurts to think about it!)

If air is pumping out air box, it's got to be the head gear is not aligned properly with the crank and the inlet valve is open for a duration of the up stroke of the piston. Hope it's not a bent or stuck valve but start with the timing marks and check they are where they should be.

Exacty as I thought......sorry to hear it. That sucks :( Is your engine an interference type i.e. valve and piston meat when out of alignment? Seen a few YouTube vids where cam tensioners have become sticky and don't apply the correct tension allowing belts/chains to jump teeth.

So its deffo not a battery or connection problem, garage says the car needs new timing chain and guide rails, he doesnt think the engine has any other damage so hopefully il be lucky and the new chain and rais will sort the problem :) but without taking the head off he obviously isnt 100% sure. He has quoted me £415 parts and labour for the job, ive said ok to this as what  ive looked at seems to be an ok price for the type of job. Just hope theres nothing more to it :)

Make sure that the timing chain tensioner is replaced as well as a stuck tensioner can cause this problem, I believe.

Just spoke to the mechanic, he repllaced the chain and rails and whatever else was needed for that bit of the job, hese done a compression test with the new parts on and says it looks like there is some damagae to the valves or other things in the engine, so hese gunna strip the head and have a better look and il know in a few days the extent of the damage :(
