Hi,

My astra has developed a strange fault in which upon turning the key ignition 2 clicks the dash lights don't come on no fuel pump noise or anything no ignition whatsoever. Radio, horn and front lights don't work, rear lights work and so does the electronic boot unlock button and interior lights. Car does not start no crank nothing. From what I can tell the front fuse box isn't powering anything but the rear fuse box is (boot, inside lights etc).

Does the front fuse box go through the ecu first and then power the components up?

12v is at starter but there is no ignition to activate the starter motor.

Where would I find the main earth straps to check they are ok?

I connected a lead from engine block to chassis but nothing, I also found wiring a multimeter to chassis and to positive terminal on battery gave 12v should the chassis return 12v?? Earth issue?

I've checked all fuses they are ok. Including the 80amp strip fuse and the larger fuses above the fusebox.

Could it be no power going to fusebox? Where does the fusebox get it's power? From ecu?

Thanks
