The lack of a WTS light is an indication the PCM isn't running, (it's Never gonna start without it). This time of year, as it gets colder, lots of people have their fuel heater come on for the first time since last Winter. It gets rotted through over the summer and shorts. This blows fuse #30 that also supplies power to your computer. If that's what you find, unplug the heater element at the bottom of the filter housing before you replace the fuse. The fuel heater is something most people don't end-up needing, so don't worry about it for now you change replace it later if you want.
Other than that, it's still most likely going to be a fuse. Check them All (esp 30, 19, 22) Twice! It's easy sometimes to overlook a blown fuse
