location of inertia switch

Good evening,

The switch is located at the right kick panel by the right front door. You should be able to see it at the top of the panel and you can push the reset as well.

Okay, a little glitch. The manual shows one at the location I told you.

The wiring diagram does not show it. There was a note that said if the switch is not there, the fuel pump control module is what controls the pump. It is back by the tank.

My truck just lost power and died while driving on the highway yesterday. Got a new battery did not do the trick. Truck will turn over but not start, seems it is not getting fuel. Mechanic friend told us to try the fuel pump reset option and we kept pushing the button but not sure how to tell if it is resetting properly or if we need to replace the whole fuel pump relay or where to start with diagnoses issues.

The button should be down if down it is working. Check fuel pressure with a gauge auto parts rent it. Also since you replaced battery try resetting security system if no owners manual look online for your vehicle on how to do it.

Also I have read some things about the fuel sensor module malfunctioning being common in an f150. Located near the spare tire, do you know anything about this?

I do not see any tips on this as normally if they go bad most mechanics put a tip in out manual with it. it would need to be scanned for codes by a mechanic to see if it is bad anyhow. If you spray choke cleaner into intake and truck starts it is probably a fuel problem but you would want it scanned prior to putting a module on it just to verify it. They cost anywhere from about $60 to 160 at rock auto, more at a dealer and a little more at a garage.

Alright so we have now tried all of this including replacing the fuel pump and the fuel line, any recommendations????

Although we do now believe that it is getting fuel. Thinkin possibly something in the motor now!

have you scanned for codes and try doing a secutity system reset. if no manual look online for your vehicle on how to do it.

Inertia Fuel Shut-Off Switch Located Under right side of dash # 7

i turned the truck off and it would not start it turns but thats it i have replaced the fuel filter and checked the pressure the fuel pump puts out but no luck there is a sticker that says to check the fuel shutoff switch where is that located and how do i check it

The inertia switch is located near the passengers side kick panel. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Ford F-150 2000 4.6 does any one know where the fuel pump cut off switch is located. I bought My truck used and cant find an owner's guide. the under hood says if I'm having problems starting the truck to reset the fuel pump with the switch, but I dont know where the switch is located.

In the passenger compartment, on the passenger side, below the dash, behind the right kickpanel.

So if you are sitting in the paseenger seat and take your right ankle and move it to the right you'll be kicking the kick panel that you need to remove.

Engine Performance problem
1994 Ford F150 V8 Two Wheel Drive Automatic

i have an automatic 2 wheel drive 1994 ford f150. i was going home one evening when my truck just died on me. i thought of everything it could have been but i just didnt work checked all my fuel pumps, lines, everything. i asked a mechanic buddy of mine from my home town what he thought it was and he said to check the fuel inertia switch, although he couldnt tell me where it was through the phone he told me to go buy a haynes repair manual book. i looked through that book backwards and forwards but never could find it. so could you tell me where miine is located?

If you have a console in the truck, it will be on one side or the other forward nexe to the firewall. If no console, it in the kick panel on on side or the other up next to the firewall.

The truck will not start... When I turn the key on the fuel pumps run for a few seconds and then shut off. I tested voltage, grounds, and resistance at different pins on the EEC computer plug. Everything checked according to fordfuelinjection.com. When ground to the #6 pin of the EEC test plug the fuel pumps run nonstop. So, I replaced the EEC computer and am having the same result. The fuel pumps continue to shut off and I don't know what else the problem could be. Please advise. Thanks.

hthe fuel pump is only supposed to run for a few seconds and turn off.

it gets the pressure up and then turns off untill you get a response from the ignition ssytem to turn it back on.

is the fuel pressure building?

I say no because i can take the fuel line off on top of the tank and it still does the same thing. I read that with the fuel line off it should continue to pump, is that wrong?

well unles your vehicle has a sensor rigged on the fuel line for pressure that cuts out the relay then no there is no way disconecting the line will do that. it turns on primes the rail and turns off should turn off when you hear the relay click off. its located near the air cleaner box.

I dont think I was clear enough in my explanation earlier. The fuel pump is supposed to pump until proper pressure is built, no? So if you remove the fuel line, then the pressure cannot be built and pump should run and run, right? In oher words would the fuel pressure regulator still cut off pumps with fuel line disconnected? It still stops running.

Also, so long as I ground pin #6 on the EEC test connector, the pump will run all day.

We know the results of that test mean: I am getting power from EEC power relay to fuel pump relay coil, from the Fuse link at starter solenoid to fuel pump contacts common pin, from the ignition swith to EEC power relay coil, also that the fuel pump and EEC power relays are OK, Inertia swith is OK, selected fuel pump is ok, wiring and plugs are ok from fuel pump relay to pumps, ground for pumps is OK, and I am getting power from Ignition switch to EEC Power Relay Coil. Also, the test bypasses the EEC computer. That is why I replaced the EEC computer. So why does it work when grounding that pin only? (And could it be the Stater bad?)

when you bypass it it just turns on the system. the fuel should stop. and then turn back on when engine is cranked. if it keeps running. like in an accident and the relays and the pump still runs but the line is split it will keep pumping gas. which is a no no.

to find out if its good or not you need a fuel pressure check guage

Use a test light check for power before and after the blue fusible link 20ga at the starter relay if okay instead of pin 6 go to pin 20 and ground it and tell me what happened.

Sorry I cannot highlight the circuitry-not allowed

Will it run if you feed it some gas by hand? Could be a bad distrib, or ign mod. Also this old, check PCM power and grounds near battery...

Okay, I had problem getting my engine to start after sitting for six months. Messed with the wiring around the rec switch did some testing and was able to start it by using starting fluid . I had removed the front tank but then faced the problem about the fuel reservoir tank. I took a small copper tube and pushed the quick connect fittings one from rear tank the other to back of main fuel pump then got wired the pump from the battery. Everything started to run okay. But now there was all the hanging front tank straps wiring for the front pump and front fuel lines hanging all all over the place. Okay, where I'm at now is I have power to the inertia but after trying to reset it was unable to get power to the pump. Was thinking maybe I can splice a new wire from pump to the inertia switch.

Hello,

That would definitely work. Have you tried to see if were getting power at the connector on top of the fuel tank? That might be where the problem lies. Regardless if you run new wires to the inertial cutoff switch, which has 12 volts, from the fuel pump, it should be running.

Thanks,

I'm working from the main high pressure pump backwards. I have power in the brown wire at shut-off switch, the second wire is kind of red. the diagram says the wire goes to the selector switch on the dash for tanks. From there to pumps. If I don't use the front tank then I ought to be able to wire the main pump to the brown wire at shut-off switch . I also noticed fuel leaking at the quick connect fitting hmm something to do with the 30 below weather hate thinking of buying a new fuel reservoir at $250.00 plus new pump and front tank but the truck has a really good C-6 transmission, lol. maybe be the first to drive from Anchorage Alaska to None the Gold Rush City, lol.

LOL. Sounds good to me. Try to stay warm and thank you for using 2CarPros.

Hmm, leaking stopped once. The main outside rail pump started {sucking} fuel . Which I hot wired from battery positive to the pump guessing the hot wire from pump goes up to the tank selector switch. Put three gallons of gas in rear tank shows the added gas so I know there is electric to the sending unit but no electric to the main pump or inside tank pump. hmm, I wonder if the fuel tank switch from my 1991 which has fuel tanks would work but it only uses pumps within the tanks.

Hello again,

A switch, is a switch, is a switch. It will just open and close the circuit. If you run a hot wire into the switch and a hot wire out of it to your fuel pump and a ground from your fuel pump, it should turn on when the switch is closed.

Thanks,

where is the reset switch, how do you reset it?

it is located under the driver side dash up on the fire wall it is a black box about the size of the pack of cigarretts. there is a white button on the top all you have to do is push it down and it should be reset.

Hi, I was driving down the highway and all of the sudden my truck died and it would crank over but not start. I have two gas tanks and switched to either...still would not start. I changed the fuel filter and now it will start and idle for a few minutes and die.Also, when I try to rev the engine it dies immediately. An auto parts store person told me he thought it was the ignition control module but I wanted to get your opinion.

The inertia switch is behind the right (passenger) side kick panel. As for the computer I have only replaced about 2 computer on a Ford in more then 20 yrs of doing this. If the switch is not causing this then I would like to check the fuel tank switching valve next. Here is a pic of what you are looking for and what you do is just push the red button this resets it and see if it will start. Let me know how that goes.

I found the inertia switch and the red button was pushed in. There was a slot that was to the side of the button and when I put a screwdriver in it the button popped up. I tried pushing it in again but this did not help. I even tried starting it with the inertia button up but I couldn't even get it to start in that position. So I guess we are off to the next item. let me know how to check the fuel tank switching valve (location would help also). I don't know if this helps or not but the truck will start and run longer on the rear tank than the front tank. neither will stay running however.

Ok remind me how old is the fuel filter? As for the switching valve it under the truck on the frame or crossover. You will need to check the red wire with the yellow stripe and make it has power to it and then you need to check the red wire to the front tank for power when on front tank and the brown wire with the white stipe on the rear tank when rear tank is selected. Now you still should check the fuel pump relay to make sure it is working as this will also affect both tanks. Let me know what you find.

The tank switch seems to be working fine. I replaced the fuel filter and I replaced the fuel relay. These helped the situation thank you.
