It's behind the console, in front of the gearshift on the ride side (not the big flat one, that's the ECU) but it's not called a Fuel Pump relay:

Why the fuel pump don't run and the relay don't click when i turn the key on?


If you can't hear your fuel pump priming then either, the pump needs replacing or the relay. If you replace the relay and you still don't hear the pump prime then it's the fuel pump.

Car will turn over but won't start. Through the


No noise from fuel pump when you turn over the car .First thing get voltage at fuel pump relay checked, is there 12 volt to the relay.If no, then problem is again the relay.--------- To reconfirm the problem, try other test, that is remove the relay and by pass the relay terminals with a jumper wire .Then with 12 volt external battery give power to fuel pump connector and see, if the fuel pump starts, then its clear that fuel pump relay is faulty.----------- Also other problem can be fuel pump inertia switch.If the inertia switch is faulty then also fuel pump will not start.-------- The fuel pump relay on a 1995 Ford Explorer is in the power distribution
box, in the engine compartment, driver's side near the firewall.----------
The fuel pump inertia switch is in the right front passenger area
it is below the dash but above the carpet in the right hand corner.--------
Its a push button type inertia switch.
--------
Fuel Pump Activation
When ignition switch is turned to START position, PCM operates fuel pump relay to provide fuel for starting engine. PCM senses engine speed and shuts off fuel pump by opening ground circuit to fuel pump relay when engine stops or engine speed drops to less than 120 RPM. When ignition switch is in ON position, EEC power relay is energized (contacts closed). Power is provided to fuel pump relay and timer in PCM. Fuel pump receives power through fuel pump relay contacts.
Inertia Fuel Shutoff (IFS) Switch
All models use an electrical interrupt switch in fuel system. During a collision or vehicle rollover, electrical contacts within inertia switch open, shutting off fuel supply to electric fuel pump. Fuel supply is interrupted even when engine is running.
A reset button is located on switch assembly. If electrical circuit trips, vehicle will not restart until switch is reset. Fuel system should be inspected before resetting switch.
IFS switch is located under instrument panel, near right side of transmission hump.
----------- If the fuel pump relay, the inertia switch and fuel pump all checked ok, and fuel pump is working with direct 12 volt source to fuel pump.Then problem relates to computer.The computer (power control module, PCM) is faulty and has to be replaced.--------- This will help.Thanks.Helpmech.

Fuel pump removale


Hi there,

Note: as your vehicle is 2009, it may still be covered under Manufacturer's Warranty. If still covered, you should have them replace at no charge.

Firstly, unless you have read your codes from your vehicle's computer and confirmed your fuel pump is actually faulty (ie Code P0203), you should should check your diagnostics first - as other electrical components could contribute to the fuel pump not working.

Start by inspecting the following circuit components:


FUEL PUMP RELAY INSPECTION


1. REMOVE RELAY BOX COVER
2. REMOVE FUEL PUMP RELAY (Marked: F/PUMP)

3. INSPECT FUEL PUMP RELAY CONTINUITY


(a) Using an ohmmeter, check that there is a continuity between terminal 1 and 2. If there is "NO" continuity, replace the relay.


(b) Check that there is no continuity between terminals 3 and 5. If there "IS" continuity, replace the relay.

4. INSPECT FUEL PUMP RELAY OPERATION


(a) Apply the battery positive voltage across terminals 1 and 2.


(b) Using an ohmmeter, check that there is a continuity between terminals 3 and 5.
If there is "NO" continuity, replace the relay.

5. REINSTALL FUEL PUMP RELAY
6. REINSTALL RELAY BOX COVER


FUEL PUMP RESISTOR

INSPECTION


1. REMOVE FUEL PUMP RESISTOR
2. INSPECT FUEL PUMP RESISTOR

Using an ohmmeter, measure the resistance between the terminals.


Resistance: 0.70 - 0.76 W at 20°C (68°F). If the resistance is not as specified, replace the resistor.

3. REINSTALL FUEL PUMP RESISTOR

If all the above components prove satisfactory, then proceed with fuel pump removal.

Access to the fuel pump & sender unit is via a service hole. The service hole is located under the No.1 Rear Seat (through the floor), so you will need to lift the rear seat & carpet, then remove the service cover.

Where is the fuel pump relay located. i have a 2003 honda odyssey 3.5 v6


  • A clogged fuel filter or problems with the electrical system powering the fuel pump can result in symptoms similar to a failed fuel pump. Have the shop verify that the pump is the problem before replacing.
Best Practices
  • The fuel filter should always be replaced when replacing the fuel pump.
Common Symptoms
  • A failing fuel pump will not create enough pressure in the fuel system, potentially resulting in a loss of engine power or a "no start" condition. You may also have a lean running condition that can set a diagnostic trouble code and turn on the Check Engine Light.
  • Fuel pumps require replacement if they leak or begin making too much noise, which is a sign of malfunction. the fuel pump relay is located under hood inside a box with alot of other fuses in it and relay it will be maked fuel pump relay

Both fuel pump relays run hot. I have replaced both of them. The truck started and ran for about 30 minutes then quit. I replaced the relays and it ran for a few minutes and quit again.


You could have a bad fuel pump relay switch. The fuel pumpmag-glass_10x10.gif relay switch gets the fuel pump running in the vehicle during the start cycle. The terms fuel pump relay and fuel pump relay switch are used interchangeably. The fuel pump relay begins its job when the automobile operator turns to the ignition on, but before the motor is actually running. At that point, the fuel pump relay in some cars sends a signal to the ignition switch, which in turn sends a signal to the fuel pump to turn on. Others fuel pump relays have actual circuitry inside of them that receive the ignition signal and directly signal the fuel pump to engage.

Have a great day!

Fuel pump relay keeps blowing on my 1996 Cadillac STS, why?


Sounds like the fuel pump is drawing too much amperage. If so, it will burn up the relay.

94 dodge grand caravan no fuel in fuel rail


Dear Ron, you have replaced fuel pump and fuel filter. You have checked the fuel pump relay. Still no fuel in rail. Try bypassing fuel relay with jumper from batt to fuel pump. If o/k then check computer for ground to relay. This system uses a relay that is operated by the computer that supplies a ground for the relay to operate. The wire color is green,16 gage. If the ground is not available then "no fuel" Check this with a test light. Key on and crank apply test light to ground wire and other end of light to ground. You should hear relay click and get fuel. If this checks out you will need to replace computer or get creative with rewiring the relay so it works without computer input. Good luck Moe

Fuel Pump Relay Switch


Underneath your hood, behind the passenger side headlight, behind the core support, is a bank of 2-8 relays. One of those relays is the relay needed for your fuel pump. There will also be a fuel pump relay fuse located there. The relay designation should be on the cover of the relay compartment.
