the computer sends power to the coil, but it needs a distributor refrence signal, crank sensor signal ect. before it will do so. If the pickup coil in the distributor is bad, or the crank position sensor is bad or cam sensor is bad, the coil and the fuel pump will not get any power. You could also check the auto shut down relay. Start testing, my self , I would look at the distributor pick up coil first.
