Got into my car Thursday to drop my mum off at work, started and ran fine.

Got home, parked up, turbo timer counted down like usual.

Got into it today

to bring it around the back of the house to fit brake pads etc.

Started first time and I got 10 meters and it cut out and wouldnt start

.

I thought the engine had flooded again so left it for 30 mins.

Tried it again it started and then stopped instantly and wouldnt start again at all just turned over, left it for 10 mins turned the key and it started and again instantly cut out and again would just turn over after that, left it another 20 mins, started and cut out again etc etc.

I Thought it might have been out of fuel so off to BP for some BP Ultimate, fired that in and again starts but then cuts out.

I remember the mechanic that did the cambelt said he had to use a jump pack to start it

(car had been sitting for a week so lost some charge most liekly) so we decided to try jumping it off the BMW and it started first time! This left us a bit puzzled as the car was turning over fine on its own and didnt sound like it was flat at all.

Left it for 5 mins, turned it off and went to start it again but again would only turn over! Connected BMW back to it and jumped it again and it started straight away so left it running for 10 mins.

Gave it a few revs, dump valve was dumping off like normal and it all sounded and seemed fine but went to move it and it instantly cut out from 2,000 revs to nothing without warning

(no splutter or anything just instantly off) and again wont start only turning over.

Car has had New Spark plugs, new distributer, new rotor arm in the last 300 miles and they look fine.

When started the car was ideling

/ revving fine with no spluttering or dodgy smoke

Checked under the oil cap for mayonaze looking stuff but nothing

Checked coolant water and that seems fine

(little dirty looking due to the old coolant pipes)

Checked oil by the dip stick and thats all still fine and at the same level and clean looking.

No Error codes

What other symptons do you get with a blown head gasket? Car idles and revs fine when jumped.

Has anyone had a similar problem and know how to fix it? Realy need to try and get this done by Mon night

Thanks
