WHERE IS FUEL PUMP RELAY PLACED IN YRV position where to find relay

It sounds like either the fuel pump relay or fuse have gone bad/blown, or more likely, the fuel pump itself has gone out. Most times the fuel pump goes bad before a fuse blows or relay goes out. Have someone or yourself listen for a humming noise when you first turn the key on. Its a good way to tell if the pump is working. I usually listen for the pump sound at the fuel fill or gas cap.

Does it have spark ? Crankshaft position sensor . If the PCM doesn't recive an input from the crankshaft position sensor it will not turn on the fuel pump relay ! GM Fuel Pump Relay Testing

It sounds like 1 of 2 problems or both first the temperature control sensor witch tells the computer the ambient temperature outside and as it gets colder out tells the computer to give more fuel the other thing to check is the throttle position sensor that tells the computer what position the throttle is in those 2 things together are like a choke on a carburetor seeing it fuel injected you can't pump the throttle you will flood it so the computer has to do it hope this works

IF YOU TALKING ABOUT FUEL PUMP.CHECK FUEL PUMP FUSE AND RELAY IF FUEL PUMP NOT WORKING.FUEL PUMP FUSE RELAY BOX LOCATED UNDER THE HOOD .IF FUSE AND RELAY OKAY AND YOU DONT HEAR FUEL PUMP TURN ON WITH IGNITION SWITCH IN THE ON POSITION FOR 3 SECONDS, FUEL PUMP MORE LIKELY FAULTY.

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.

COULD BE FUEL PUMP,CHECK FUEL PUMP FUSE AND RELAY. LISTEN FOR FUEL PUMP OPERATION IN FUEL TANK WHEN YOU TURN IGNITION ON POSITION YOU SHOULD HEAR FUEL PUMP RUN FOR 3 SECONDS AND TURN OFF.

Hi,
the fuel pump relay performs a slightly different function than the horn relay. If there is a wiring circuit printed on the outside of the relay's you will be able to see the difference.

AS you have "jumped" the fuel pump relay and the vehicle started, then the relay is not providing sufficent consistent power to the fuel pump. It is possible to check the relay using a digital multimeter, that will indicate which side of the relay is failing.

The most expedient method to address the potential and factual problems which you state, is to hook up a hand held :reader" to the car and observe the information given. That will give you a factual baseline to start with.

Good luck.

The fuel lift pump relay is placed in the fuse box / relay plate fascia 2 for 2007 Audi A3 2.0 TDI. The fuse box / relay plate fascia 2 is placed above pedals behind a plastic cover. See pictures below:

The fuel lift pump relay is placed in "2b" position in the above picture.


Please do rate my response. Thanks!

Good info on the PATS / theft light. Looks to be the PATS / HEC operation is functioning correctly

The Fuel inertia switch only cuts power to the fuel pump, so if tripped, the truck would have a crank no start issue. Do you have a crank no start, or no crank issue.

To reset, just press down on it. To check if the switch is tripped, check for power at the connector to the fuel inertia switch

Engine compartment fuse # 10 ( 20A ) to the fuel pump relay -> Dark Green w/ yellow stripe wire to the fuel inertia switch -> pink w/ black stripe wire to the fuel pump module.
Check the pink w/ black stripe wire to ground with a meter for power, with the key in the run position.

If you turn the key from off to run ( do not start ) you should hear the fuel pump cycle ( hum, then turn off ).

Could be an issue with the fuel pump relay ( my '01 had a crank no start at ~ 35K miles, bad fuel pump relay ). I proved this out ( after a stupid ID10T error in my diagnoses process ) by jumpering the normally open contacts in the fuel pump relay socket, and then installing the trailer tow reverse circuit relay into the fuel pump relay socket ( same full size Ford Relay ).

Jumpering the fuel pump relay in the relay socket ( remove relay and use jumper wire ), red line


If you have a no crank issue, could be the DTR ( Digital Transmission Range ) sensor on the driver's side of the trans is out of alignment.

Check the start motor relay ( on the firewall on the passenger side ) for power on the Tan w/ Red stripe wire when the key is in the start position ( this is from the ignition switch through the DTR when in park or neutral to the starter motor relay ).

You can test another route, turn the key to the run position, and apply power to the Tan w/ Red stripe wire on the starter motor relay in the engine compartment on the firewall. BE CAREFUL, the motor should turn over, keep clear of moving parts.

Post back a comment to this problem with the results of the testing.

Thanks

You should test your fuel pump relay. Do you have any codes in the computer?
