I would do a scan for any codes first and just make sure all electrical plugs that you have undone are tight. There are simply too many things that can cause this to just guess or throw parts at it

See the guide below

What is the engine code / size of engine?

Yes, that could be a crankshaft position sensor. The engine will not start if there is a problem with that sensor.

You should get a code if that sensor is faulty.

Sudden engine stop after 3 km, later the mechanic remove the thermostat and it has failed completely after even fixing back the thermostat. What could it be? Now the car does not move completely, the mechanic has failed to repair it.

Is the engine running? Was the engine overheating when you had the initial problem?

No it was not heating, the problem was the engine stop after short drive. Mechanic thought the thermostat was the problem. He was trying to get the problems. But now the car not starting any more like there is no current for the ignition

First be sure all your connections are clean and tight. It may be the starter isnt liking the cold weather and is drawing more amperage than your battery can supply. You can have a cranking draw test done on the starter to see how much it is pulling, but I suggest you do this when it is cold out so it is the same conditions of when it is failing

Listen to your car's pump. If you hear it check for the spark, if you don't see the spark, look into possibly replacing plugs, wires, cap or rotor. Hope you'll get it running soon.

Hello
I have a 2006 vw polo 1.4 tdi, and I'm having a bit of a problem to solving a fault in which the engine sometimes won't start, the engine cranks at a good speed, and after a few tries it starts. I replaced the heater relay and checked fuel press all seems ok no faults are showing.
Any idea what the problem might be?
Regards
Matthew

If you crack an injector line do you have fuel pulse on cranking? Compressions ok, maybe a fuel drain back problem, any signs of fuel leak around the injection pump?

There are no signs of any leaks, cannot check for fuel pulses since this is a pompe duse engine, compression seems ok too, replaced the camshaft sensor but still problem remains. Some times it starts for a second then goes dead again, and after many more tries it fires up. Have checked all wiring for damage and cleaned all connections found, I'm now starting to give up

If you remove the inlet pipe to the injectors, why is there no petrol leak?

I'm not sure you are removing a fuel line. Can you post a picture of what you are removing?

Engine does not start. We replaced the motor with another one. All the wiring has been put back exactly the same way as it was. The engine turns perfectly but does not start. I have checked the plugs for a spark and there is none

Please advise
