1.6 won't start when warm

[skifree]

My tired 1.6 starts right up when cold all new glow plugs.If I shut it off, it will still start back up, but if it sits for a while and is still warm the glow plugs won't come on and it won't start. The battery is fresh. Has any one put a over ride switch for the glow plugs? Or is there another solution other than a rebuild?

Check your cables to and from the starter. I had the same problem and it was bad wires

The engine turns over,but it won't start when warm without the glow plugs

I have had that same problem- my compression is a bit low I think.  
   My solution was to pull the wire off of the coolant temperature sensor near the head which goes to the glow plug circuit.  the plugs will then glow as long as you want, every time.  they go off after you turn the starter.

Thanks for the help. That will help me till I put my rebuilt 1.6td replacement.

I accidentally SLIGHTLY bent all the intake valves in my first TD engine while monkeying with cam timing. Started great cold, but wouldn't start hot.

I set the timing to .88 mm and have been leaving the cold start on all the time (cable sticks) is this ok? Started warm same way, when cold start was off.Does any one know how much the cold start advances the timing?

If I remember correctly, the cold start advance advances the timing 2.5 degrees.

And, it doesn't hurt to leave it pulled out.  As I remember, the pump overrides the advance internally at speed.

I have my pump "advanced" externally at the mounting bracket by about 2 degrees.......engine "whacks" a little louder at idle.

You will wear out the advance piston with time, especially if you sit at idle or low RPM a lot when the advance is not taking over
