Cold Start problem?

[Sean]

Why has my FC3s suddenly lost the ability to start when it\'s cold?
it\'ll restart from warm no problem but when starting from cold it\'ll eventually fire..... rev for a split second and cut out again. It\'ll do this for about 3-4 mins until it begins to warm then it\'s fine again

Any ideas anyone?:confused:

Sounds like fouled plugs to me??

Maybe too cold a grade??

[Sean]

Hmmmm ........ Never thought of that.

Ring square seals?
(water in your engine when cold - takes time to leak back in hence when warm it\'s o.k) - mine does this!

[mikeeech]

mind you when it does do this it runs really lumpy too!

[Sean]

You have just described the problem I\'ve got!!!

Whats a Ring square seals?:confused:

[Sean]

Just spoke to pip he said the common fault with this symptom is the water temp sender being disconnected causing the ecu to think that the engine is already warm. Where is this sender so I can check it out?:confused:

[grinder]

not sure on this one - but according to one of the manuals it looks like it sits on the back top of the water pump ( thing with the fan connected to it ) but its called a water thermosensor connector !

happy hunting

[grinder]

[Sean]

Right, the master cylinder is back together (just needs putting back in the car!! WAHOO!

Only problem now, is I\'ve lost nearly all the fluid and I don\'t have any and I can\'t nip out to get some cause theres no clutch fluid in my car D\'oh!:spank

[grinder]

Step 1 - Make sure you have all equipment at hand before starting job ( jack , spanner , new fluid )

It\'s okay... I walked to the local petrol station, they had some:rolleyes:


All thats left now is the cold start problem!

ring square seals...

This is the problem with mine. Rotechnics diagnosed this one when the coolant leaked out. The ring square seals are the engines equivalent to a head gasket and separates the combustion chamber from the water courses in the rotor housing.

Mine have deteriorated with age with the result being that - after not being used in a while - the coolant leaks into the combustion chamber and makes the plugs wet etc. This makes it lumpy when cold.

As the engine warms up then the coolant will just be burnt off as steam providing a leak is not too bad.

Mine is not too bad at the moment - I only get this problem after 3 - 4 days of the car not being used but whilst I save my pennies for a replacement engine (yep it gets that bad) I\'m running around in a vw polo (1.0!!!)

...It\'s o.k my ego can stand it - I have strength of character... and despite what my wife says about the size of the wing on the back and it\'s relationship to the size of my... well you know... it\'s now so clearly not true. By driving a vw polo daily I must have the biggest...

I\'m going on too much I think!
