Check the tach input wire with a test light and see if it pulses rapidly when the engine is running. Or you can use a multimeter, set it to ac volts and ground the black lead. You should see 6v to 8v at idle if I remember right. Also check the power connections, I believe there is a seperate power and parking light wire depending on the model, im not sure how yours is. If they did work under the hood, they might have loosened or disconnected the tach wire. Usually that is connected at the dist.
