i have an 88 supra turbo and it has a push start button. now whenever i flip the switch to turn on all the elctronics in the car my fuel pump makes this buzzing noise almost as if though it was a bee. i know i need a new ECU but i was wondering if anyone could shed some light into telling me what is wrong with it. i have also heard of a couple mods that you can do to the fuel system due to the cut off problem MKIII have. any kind of help would be greatly appreciated.
