My boyf subaru wrx impreza wont start?? we've tried jump starting it, also checked the fuses which are ok,?

sounds like some botched electrics. My subaru's electronics were ******* up and the mechanic told me I needed to put a paper clip into a wire port. Seemed to work, but dont go trying it in any port, because he also mentioned that you can short the whole ECU and wreck your car
