So, how do we know if a starter is'nt turning fast enough? & how can we tell is the fuel pump is producing the min required pressure?
Lexia can read the starter speed from the crank signal and the fuel pressure in the common rail from the common rail pressure sensor. In fact the ECU uses both of these to inhibit the injectors from firing if either are below threshold.

Thanks for leting me know this. I do have a lexia diagnostic interface, I just dont use it very often as my laptop is a real slow slug with the software running on win98 and often just frustrating to use. But i will get it out the cupboard to check this out and make comparisions about the starting data.
