i went out to start my Supra which is sitting in my driveway with a BHG, but it will still normally start except for today. I went out there and tried to start her up and all i get is" fwap fwap fwap fwap" really fast, its not turning over its just going "fwap fwap fwap fwap" then i popped the hood to see if i could find any obvious reasons and i couldnt but i did happen to take the radiator cap off and the coolant burst everywhere! WTF is goin on?
