Ok see whre you are now Al . . Op was recently asking for an ECU from the same model so thats should be ok .
But can see that if this issue has caused all the original dash bulbs to blow . . .by changing the complete pod (hopefully for the correct one to suit the car & engine) the same bulb blow would occur when the replacement was fitted & switched on .
IMO what the OP needs to find out is . . .is power getting to the ignition circuits ?
hence my question about the ignition switch.
is it possible to check if power is getting to the ignition switch & then is it coming out again & powering up the systems ?
Just remembered had a very similar thing on a transit van . . no ignition lights at pos 2 but engine would turn over at position 3 (start) but would not start . Fault was faulty ignition switch
