Signum intermittent starting problem

[kildrum]

Hi all. My 2004 Signum 1.9CDTI has recently started giving random problems starting from time to time. I have noticed on the dashboard display after turning the key to position 2 if the engine management light comes on and I can hear the intank fuel pump running it will allow the engine to start OK. The times that the engine management light doesnt come on, there is never any sound from the fuel pump and the starter motor will not turn over. A yellow hazzard/skid triangle illuminates. Usually, after switching the ignition on and off a few times the fault will eventually clear and the fuel pump can be heard running before the starter will turn the engine over. I was wondering if the in-tank fuel pump tends to give trouble in these models or am i completely looking up the wrong avenue! Any help is greatly appreciated. cheers

Im no expert but that sounds like the characteristics of immobiliser problems...

Hi, Thanks for that. Do you know of any fault diagnosis equipment I can purchase that would put me in the right direction?
