Fuel pump inside fuel tank accessed by removing plate on forward facing tank panel.
Inertia switch is inside boot/trunk
Ign module is plugged into side of distributor.
The coil is a standard 12 v ignition coil.
The ecm is located projecting through the bulkhead (firewall) by the drivers feet.
You can access the trouble codes with a scanner plugged into the socket in the engine compartment drivers side or by counting flashes of light on a 12v testing light as described in the Haines Manual

Unplugging the fuel control relay or module will ensure no current is entering the wire heading towards the fuel pump. The likelihood is there is a short circuit somewhere along that part of the circuit though it is possible the relay could be faulty.

Ideally, with the aid of a circuit diagram, the wire should be traced from the source at the fuel pump module along its length until the fault is discovered. There is intelligent equipment available that can locate short circuits.

No driver module shown on the wiring diagram for 89-98 models.
There is an EEC relay that powers the fuel pump relay. The fuel pump relay is grounded by the PCM. The voltage goes from the fuel pump relay thru the inertia switch and on to the pump.

1990 f250 7.5 the injectors will not work replaced fuel pump ecm end the pick up coil in distributer and the ecm

Check with your parts man and see if your Year model uses a ECM Relay. There is a fusible link and an Inertia sensor too.. The inertia sensor is either in the area of the passenger kick panel ( may have access hole) or the drivers kick panel (may have hole). Either side you need to push button on the switch to reset fuelpump.

If that does not help I understand a fusable link is either feeding the Inertia switch or the ECM Relay.

1990 Lincoln TC fuel pump dead

from the ignition switch or the starter, power is taken fromeither of these points to fire the fuel pump on start. This is what charges the fuel system so that you can start. then your fuel pump goes into run mode.

If someone can make a power check on the wiring going to the fuel pump with the engine is being cranked, you can possibly solve your problem.

1999 lincoln fuel pump

My fuel pump on my 1998 Lincoln Continental has no power. I checked the fuse it is good. I checked the fuel shutoff switch it was fine. I have traced the wire from the fuel shutoff switch to the fuel module driver in the trunk. The wire has power. I have also traced the positve wire from the fuel pump to the fuel driver on a different terminal, this wire has no power from the pump. I also changed the fuel driver, the low fuel pressure switch, the alternator, and battery.does anyone have any suggestion's?
