Gee, I have the post before yours w/ an '88 245. To burn up the excess fuel try to pull the fuel relay below the glovebox (white), to be safe I have the key off. Then try starting. Once it trys to start, that's a sign it burnt off the fouled plugs. Then put back the fuel relay & start it (hopefully). I know this is just a temporary workaround, but it beats waiting an hour for the plugs to dry off, if that's what's happening. (I think another way to do this is to disconnect one thing to the fuel injectors to prevent them squirting in the engine, I forget exactly where that is though).
