My Omega 2.5 has an intermittent fault, sometime's it will start up straight away other days it will just sit and turn over. To get it to start up when the fault is happening, i get a little tow from another car and it start's all day long.
Does anyone have any idea what the fault could be or if the immobiliser can be by-passed.
Many thanks

do a paperclip test, bet you get a code 19 - crank sensor  :y

Whats a paper clip test, and thankyou

have you done the paperclip test,if the sensor is gone you should see code 19 and 31 but ignore the 31 as its because the engine is not running
