Sounds like you have an ignition problem. the control unit needs an ignition signal for the box to ground the fuel pump relay. Use a test light at the negative side of the coil and a good ground. The light should flash when you crank the engine with the key. If not, you may have a problen with the pick up unit in the dist, or the ignition module itself. The signal that turns the coil on and off comes out of pin 7 of the ignition module. Make sure the module is the correct one, non turbo cars with EZK ignition have pin 7 missing. The non turbo module won't work on turbo cars.
