Thank you for your help and tips I am not familiar with Porsches and your tips pointed me in the right directionI think I have found the problem
I checked out all the circuits of the DME relay and all seem to be working okay specially Earth and positive feed to pump when turning over engine was present
I managed to locate fuel pump and when cranking I had earth and positive feed at pump but the pump was not making any noise at all So would I be right in thinking that the pump is faulty

Hi I have sorted this problem now
It wasn't the fuel pump in the end I spent some time trying to diagnose this thought I unplugged crankshaft sensor and speed sensor and checked for resistance I found there was no resistance on the speed sensor so I jacked the motor up and put on axle stands went to have a feel of the senses and found that the bracket has come loose the bottom bolt had fallen out and Swan in to the ring gear which grounded speed sensor down so fitted new sensor new boult to bracket set up now running fine
Thank you all for your help
