    checked fuses related to fuel system/switched relay/ pulled wire connecter under rear seat check for power up when key turned on only one wire has power at all times (key on) . Is sending unit and pump one unit. or possible inertial switch triggered can not located checked a/b/c/pillers

    In addition the only wire hot with key in on position is yellow with a red tracer.Located in center between orange and a brown wire.There are also one blue with red tracer and white with a black tracer.the connecter is located at the top of fuel tank under rear seat. Vehicle is low on fuel. Quit while driving. Had a dead cell in battery, replaced it .Alarm system seems to be functioning properly. Could fuel pump be the culprit.Note all fuses good and switch relays in fuse box relays do have power.

    There is no inertia switch on that model vehicle.

    The fuel pump and the sending unit are seperatly wired.

    *** What colour is the wire with the power in it under the rear seat access hole?

    Please advise.

Most newer cars have a relay in the fuel system to shut it off when fuel pressure drops below the norm. this keeps your car from running lean and burning a piston. i whould replace the fuel pump. the fuel pump may work when you take it out but that dont mean it has enough pressure to opperate your car.

hope this helps . good luck

I backed into another car to hard and it triggered the cut off switch to my fuel. I would like to know where it is located


NO, my guess no start, and you didnt check fuses first, the FI fuse kills the pump dead, fuses are always first.
94 metro? no engine size stated, so ahd to look at them all. 3

its not a ford is the answer, its really a suzuki swift .(in Gm snake skins)
and you busted a wire to the pump back there.
or the connector just popped, the suzuki cooler for pump is pink.
the pink is the biggest wire in the harness there.
the fsm shows this in the last sections for harness wring.
12vdc cranking engine, is the power to the pump and rules.
got spark? x3 or x4 (engine options vary)
if spark is lost on all cars the ECU brain cuts fuel.
(for 3 reasons total , ask)
1.0L 1.3 single cam, and 1.3L twin cam.
all three have same wiring and colors for fuel pump relay.
and same logic.
here is one , at random, picked.
if the ECU sees good park and TPS not stuck at full throttle (WOT)
then it closes this relay , cranking, (and running held)

FI fuse and IG-coil and dome fuses must be good.
the CEL lamp (dash) must glow keyon, or fuse blew..
i have all diag, info on this car, ask. tell all symptoms first.
no inertial devices , only on fords


>


i learned today how to get larger images.. first time ever.

recap.
1: fuses good
2: CEL lamp glows (keyon in dash) check engine light .
3: spark must happen !!!
4: Fuel pump relay closes cranking
5: 12vdc hits Pink wire here, (PK)
6: the black ground wire, must be good. at pump.

My fuel pump is not getting any power the fuses are ok


Check the fuel pump relay located in the fuse panel under the hood. Switch it temporarily with the horn relay or the a/c relay. Check for power at the pump. If it starts it's fixed and u now have a horn inop or ur a/c is inop. Change relay is the fix. If no power to relay check wires for corrosion and check continuity. If wires are good and you end up with power at the tank , then the problem might be that u need a fuel pump rockauto.com has great prices . Check em out! Have someone set ebrake and turn the key holding it in the on position. Bang on the tank with a rubber mallet. If it starts u kno it needs a fuel pump.

I'm not getting power to my fuel pump fuse. All other fuses and relays are fine. I'ts getting power to them, because I checked them all with 12amp volt tester. My car was broke down about a mo


You may have an inertial switch triggered, or you may have a faulty wire between the fuel pump relay and it's coil ground. If you jumper the switched contacts with a paper clip and fuel pump runs, the issue is likely a faulty oil pressure switch if you do not have an inertial switch- it would be down by the brake pedal pivot at the firewall if you have one. The oil pressure switch would be screwed into one of the galleries and it is not the same one as the gauge uses.

No power to fuel pump on 1999 crown victoria


Hello abzalkhan193
Heres a few things to check that could cut power to the fuel pump. The fuel pump inertia shutoff sw
in the trunk on the left side, there is a reset button on the switch if you push the button down and
you hear/feel a click then the switch was tripped and you just reset it. The switch's job is to cut off
the fuel in case of an accident. Next, the fuel pump fuse located in the battery fuse block under the
hood on the right fender well, fuse #1 20amp fuse. Next, the fuel pump relay, the relay is located in
relay center on the left fender well. Hope this is helpful.

No fuel pressure asd&pump relays energized


The fuel pump relay won't energize if the ignition is bad, or the fuel safety cut out is bad. Don't know what Dodge uses. Ford has an inertial switch in trunk. Many cars use the alternator. Some use extra wires to the oil pressure sender. Try looking at the wiring diagram on relay side, and jumper the outputs where relay plugs into, bypassing the relay completely. The pump should hum and you should get pressure. If not, make sure the tank isn't buiding up vacuum, and make sure the power and gound are good at the pump.

Chevy cavalier 1998 2.4 ltthe motor starts but sudenly stops after 10 or 20 seconds running i cheked the gas pump line and it works ok, spark plugs are ok fuses oare ok the swuitch ignition seems to be in...


the fuel pump is triggered by the engines oil pressure switch upon starting
when oil pressure reaches normal psi the relay takes over powering the fuel pump
you see know that your relay is not operating now for the pump

You could always run a fused wire from the fuse panel to the relay. This way when you turn the key, power goes to the accessory on the fuse panel, the fused wire you installed, and to the relay circumventing the problem and creating a protected circuit.

O sound from fuel pump


Always check the fuses first, because they are so easy. Also, the relay may be at fault. You should hear this click when you replace the fuse for the pump with the car ON, but not started. If no fuse problems, then check for power @ the connection for the pump after removel of the electrical connector. If you have power here, then it is a bad pump, or connection.
Good Luck!

1cant figure out why i only get power to the fuel pump when i run a hard wire from the battery to the relay i have tested the relays and they are ok


Did you see if the inertia switch was triggered. The emergency fuel pump cutoff switch, also known as the inertia switch, cuts power to the fuel pump in the event of an accident - even a slow speed one - any sudden "jolt" can trigger the switch. 

The switch is located inside the jack storage compartment found at the right rear of the vehicle. Remove the cover and it is behind the thin "foam" covering inside the compartment towards the rear of the vehicle. 

It has a red button on the top of the switch, make sure the button is fully depressed. If it is and the vehicle still won't start check fuel pressure at the rail (there is a port on the rail which is under the hood on the engine) with a fuel pressure gauge. If the pressure is ok (about 30 psi) the problem is most likely not fuel system related. 

Good luck and hope this helps.
