Intermittant starting problem
 

My car is suffering from an intermittant starting problem and looking for your advice/suggestions please? My car is a 99MY turbo and the last time it failed to start was about 2 weeks ago where I had to bump start it. The sigma alarm and immobiliser operate as normal but only on the odd occasion when I go to turn the key nothing happens. I replaced the starter motor 3 weeks ago now and obviously this was not the solution :wonder: Ideas welcome...
