this is a *long* shot but I've seen it on two cars...
there are three connectors from the inside of the car that go to the area directly beneath the fuse block under the hood. We had a no fuel pump situation and my buddy the Saab Master traced the signals to the center of the three connectors and we thought why not, it's free, take a shot. We unplugged and reseated (plugged back in...) the center connector and life was good again. did have to do it about 5 or 6 more times over 2 years. symptom was crank and crank but no start. determined it was the fuel pump signal that wasn't getting through, jumped power directly from the inside rear light to the pump and it worked. Just about *all* of the signals from the inside of the car (and all of it's fuel ecu, relays and the like) go through one of these three connectors.
So if you want to take a free shot...
Best way to do this is:
Open drivers door, squat on the ground, using right hand put it up and above the hood release, go more and slightly forwards and you will feel the three connectors (they are about the size of a pack of gum), wiggle and pull to the center of the car (one at a time please) to disconnect, and then reconnect. do all three and see if you get lucky.
