Is all the wiring back where it was ? Did you break something ? A sensor may be near the thermostat housing . And you're not pumping any gas , sounds like the coolant sensor is not hooked up or broken .

There's a chance the coolant temp. sensor decided to quit at the same time by pure coincidence .
