fuel pump cutoff switch in the trunk in a 98 towncar. it is on the driverside
on the top shelf in between the body and trunk lid mounting bracket. push the
button on top of it and see of that works. if not theres a fuel pump relay under hood in relay box
check the spark plugs to see if they are getting any spark-pull one of the plugs, reconnect the wire, and hold near something metal on the car while someone turns the engine over-if no spark-it's electrical-maybe just the plugs-maybe something more serious
try restting the inertia switch in the trunk. When you turn key to "ON", the fule pump will run for only 5 seonds if the engine does not start. Listen at the fuel tank for humming of the pump.
The PCM, Powertrain Control Module controls the fuel pump relay. So, when you turn key on, the power relay powers up the PCM and the PCM powers up the fuel pump relay.
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.
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?
