Engine died after water splash

I have a 97 Grand Cherokee. I went through a water puddle at 40mph, the car immediately began making a clicking sound on the passenger side when the car was in motion and when it hit approx 40 mph a second clicking sound was heard inside the car under the automatic gear shift on the floor. After driving another 15 miles the car shutoff at a stop light and would not turn back on. No check engine light but the empty gastank light stays lit even after adding gasoline to the car. Any ideas?
