    as far as i can tell the relay is good. there is a relay next to it. i switched them out. the same result. the fuel fuse in the same box is good and has power to it. thanks though!

    I tested the relay terminals as you suggested. They all lit up as you said . With the key on the ground was bright and the other two lit up well. Does this mean a relay is bad? Thanks for your help!

Hi, have you checked the fuel pump relay? It is turned on by the PCM. You can try swapping it with a similar relay in the box under the hood. If that doesn't work, probe the relay socket with a 12 volt test light to see what's going on. With the key off, there should be one hot terminal in the relay socket. With the key on, there should be 2 hot terminals and one ground terminal. To find the ground terminal, hook the test light clip to battery positive and probe the socket. A grounded terminal will light the light brightly. The pump terminal should light the light dimly. The 2 hot terminals should not light the light at all. Please let me know if you have questions, and thanks for using FixYa.

    since you have swapped the relay and all the relay socket signals are good, the problem is downstream from the relay. Just for grins, pull the relay out, turn the key on, and then push the relay in to make sure it clicks when you push it in. Doublecheck for voltage at the fuel pump. If there is no voltage there, trace the wires back to the relay. You've got a hard one. :-(

Where is fuel filter


The last picture below is a picture of The fuel pump inertia switch for a 1997 Ford Escort. it is located inside the trunk immediately below the hole in the trunk side trim on the drivers side. You first should disconnect the electrical connector for the inertia switch. Then start engine and let run till the engine stalls as to relieve the fuel pressure. Make sure to reconnect it after finishing the replacement of the filter.

Replay pulled out of box car still runs 1997 Thunderbird


The fuel pump is failing the pressure check valve is no good, it should hold pressure after shut down and not drop more than a few pounds. the pump will; need to be replaced. You need a car lift to replace the pump as the entire exhaust system must be unbolted and removed to get the tank out of the car, there is not enough clearance on the ground to do this.

1991 Ford Thunderbird V6 3.8 - Starting Issues


Maybe something wrong with inertia switch? Part of diagram so you can see inertia switch wire colors. How long since a tune-up? Any applicable trouble codes? Also, use a gage check proper fuel pressure, my info says 35--45 psi. I've seen fuel pumps that would run, but wouldn't make proper fuel pressure. I'm not saying the fuel pump has a problem, at the moment, I don't know?

My explorer starts up, runs a few seconds and dies. what could be the problem?


Sounds fuel related, change the fuel filter if you haven't in the last 30K miles, if it is still doing it, have fuel pressure checked. If it still does the same thing it could be your fuel pump system. Check fuel pump relay, inertia switch (if applicable), fuses and lastly the actual fuel pump.

1997 Ford F150 Electric Fuel Pump will npt pump


Did you check the fuel inertia switch in the passenger side kick panel ?

The fuel pump is powered :
the fuse to the fuel pump relay.
The fuel pump relay to the fuel inertia switch
The fuel inertia switch to the fuel pump itself.

At the fuel inertia switch in the kick panel, power from the relay is the Dark Green w/ Yellow stripe wire and the pink w/ black stripe wire is the power. from the fuel inertia switch to the fuel pump.

If you jumper the fuel pump relay, you should hear it run. If not pull the fuel pump relay, and check the pins in the relay socket, pin 30 should be the power from the fuse.

50b0c31.jpg

If you have power at pin #30, jumper the relay socket as shown with the red line above, and check the dark green w/ yellow stripe wire at the fuel inertia switch for power.
Press the button on the top of the fuel inertia switch, and check for power leaving the fuel inertia switch on the pink w/ black stripe wire.

This is tests good, check for power at the fuel pump, same pink w/ black stripe wire.
Fuel inertia switch info is in the owners manual, If you did not get an owners manual with your truck ( purchased used ), you can download one from Ford :

?87 F-150 5.0 stalled and won?t restart. Electric


Is the fuel pump inside the fuel tank? If, so, you could try disconnecting the wire harness at the tank, and hot-wiring the fuel pump directly to a 12 volt source, in the correct polarity of course! If the pump runs, your problem may be a fuel pump relay, or a wire problem or connector problem. If the pump does NOT run, post that info. There may be a way around the problem!

Fuel Pump Circuit Operation When the ignition is switched to the ON position, it turns the EEC Power Relay on. The EEC Power Relay provides power to the EEC-IV processor and the control side of the fuel pump relay. Power for the fuel pump is supplied through a fuse link or high current fuse attached to the starter solenoid (battery side). From the fuse link or high current fuse, current flow is through the fuel pump relay and Inertia Fuel Shutoff (IFS) switch to the fuel pump. The IFS switch is a safety device used to shut off the fuel pump in the event of a collision. If the IFS switch is "tripped," it must be reset by depressing the white or red button on the top of the switch. The fuel pump relay is controlled by the Powertrain Control Module (PCM).
When the ignition switch is turned to the ON position, the fuel pump will operate. If the ignition switch is not turned to the START position, the PCM will shut the fuel pump off after approximately one second. The PCM will operate the fuel pump when the ignition is in the START position to provide fuel while cranking.
After the engine starts, the PCM will continue to operate the fuel pump unless the engine stops, engine speed drops below 120 rpm, or the IFS switch is "tripped."

System Diagnosis Note: Grounding the FP lead at the DLC will allow the pump to run continuously with the ignition switch on.

Change fuel filter 1988 ford thunderbird 6 cylinder


In the trunk left side is inertia switch.  rap ******* side with fist, causing button to pop up on top, when this happens the fuel pump will no longer receive power.  Now try to start vehicle, should attempt to start and die.  Fuel system is no de pressurized.  PLease be careful as there is still some pressure in system! and remember to reset inertia switch when done by pressing pop up button back to the down position.
