Polo tdi fuel pump

SOURCE: vehicle just keeps cranking wont start.

Make sure that your fuel presure is up to at least 60 psi if not that could be your problem. If not, make sure you are getting spark, if not could be your Crank sensor or ingniton module ECM. Usually if your Engine control module wouldn't be bad because of your fuel pump is working, but may not be putting out the proper pressure for the fuel system. Fuel Pumps are a Problem with that year..

What about the fuel filter????? Have you changed it out??? If you can spary something like a started fluid, that means it is a fuel problem. My last check, it has to be above 50-psi on the fuel pressure to make it run right. I had 35psi, but whould not get over 30mph or down hill maybe 45mph. Check both filter & pressure, but check pressure with a New fule filter!!!!

This is very important for Audi 1.9 TDI engine: IT IS FORBIDDEN TO RUN WITHOUT DIESEL FUEL IN RESERVOIR !!!
This type of engine is equipped with pump-nozzle injectors which develop up to 2050 bar injection pressure !
Remove the fuel filter, fill up with diesel fuel and put in place. After that try to start the engine with accelerator pedal to the floor. Heed of electric starter motor temperature and battery status! After 40 - 50 sec. of start attempting wait for 1 - 2 minutes for battery and electric starter motor revival. After few starting attemptions the engine must start.
