My skoda 1900 diesel starts every time when cold but never when warm?

i have to wait 1 hour for it to cool down, then it starts without problem. it runs perfectly, there are no leaks in fuelpipes, no air in fuelpipes, starter perfect, battery perfect. fuel cut of cellanoid works fine. HELP please

Answers:
Fit a coolant temperature sensor. No tools needed, fits in 1 minute. This is the most common fault for non start when hot.
put an ice pack on it when you turn the engine off.
Is it flooding when you try n start it warm?
Its possible you have a faulty fuel injection pump or fuel injectors?
Sounds like you have a vacuum leak, change the fuel filter
and fill it with fuel conditioner, this is often the culprit.worth
trying this first.

Interesting! During the really hot weather in July I had a similar problem with my Mercedes E190. In the morning she started as bright as ninepence and with her sitting in the car park all day in the burning sun I had a problem.
I suspect that it has something to do with the fact that I haven't had her serviced for quite a while and maybe the contacts or the spark plugs are getting that little bit further apart for the ignition.
The heat will cause expansion and so the gaps may be bigger.
I have to take my car to the mechanic - sorry to tell you this - but I am female - haven't much of a clue!
check the engine code so that you can ask dealer if manual/hydaulic tappets ,if latter tight tappets could be the culprit.
Skoda diesel? Wow! If you fill it with fuel the diesel must be worth more than the car?
you are very blessed i did not know that a skoda would start at all my advice would be to pour petrol all over it then it would start straight away and it would probally be worth a bit more
