Battery had died on my evo, completely flat. Have charged it back up but now it wont start at all. Doors unlock with the keyfob and all dash lights come on as usual. I think its the standard immobiliser thats on it. The one where I press the other small fob twice beside the ignition as it clicks a third time allowing you start the car. But now it does not click at all. Not sure what else to do? Useless with all this electrical stuff.
