can anyone help,got a 95 wrx runs perfect just sometimes wont start.it can start and stop for 2 days without problems.then out of the blue will not start,just cranks over but will not fire,then after 2 mins of messing around it will start.it has a meta immobiliser but that seems to be turning off ok.when it does start it is like offering to fire then does and the car will then run fine????
