READ THIS CAREFULLY 700 1985

As Aleekat and Aye Roll have tried to tell you, the problem is NOT the fuel supply. It is most likely to be the hall sensor or its connection in the distributor. This sends electrical pulses to the ignition computer which then powers up the FI relay, then the fuel pump. It is a CHAIN of events. You have to try to understand how the car works. If the hall sensor is dead the fuel pump does not operate (to prevent the engine from flooding / fuel leaking). You seem to be assuming that if a component fails to operate, then the fault is with that component - a common mistake with amateur mechanics (we ALL do it sometimes). The fuel injection system is more complicated than that - if you take time to read the FAQ (which Steve Ringlee has spent hours compiling for the benefit of all of us including yourself) you will learn a lot about your car. You need to read the section on what happens when starting, then you might begin to understand the bigger picture instead of keep guessing at the "quick fix". Regards.
