Yes. It is located under the right (sitting on the bike) below the seat. The fuel fitler is located there as well. Remove the seat and forward rear wheel guard portion that is under the seat. The fuel pupm can be operated by pressing the starter button only, if your clutch safety switch has not been bypassed. If it has, then the starter wil operate (and your cruise control will never operate) Pressing the starter only, allows you to "Prime" the carbs to fill the fuel bowls up proir to starting.

No power to fuel pump

If the old fuel pump failed, it may have blown a fuse or damaged a relay, so check those first. Your owner's manual should show where to find them. Usually, you can borrow a relay from another circuit for testing purposes.

Then, you need to determine if the wire from the engine compartment to the fuel pump is receiving power. A $3 test lamp with thin probes at each end should answer that question. While the engine is cranking, touch one end to what should be a "hot" connection and the other end to a good ground -- if the lamp lights, you've got juice.

If the wire has power, then check connections at the fuel pump that may have been mis-wired or come loose. If you have to remove the fuel pump to do this, hook it up directly (and briefly) to your battery to see if it runs ... even brand-new fuel pumps have been known to be defective.

If you're satisfied that the wiring, pump, connectors, fuses and relays are all OK, then the engine computer probably isn't activating the fuel pump relay for reasons best known to itself. Assuming the computer itself is receiving power (check fuses and relays), then you'll need to do some systematic electrical diagnosis, since there are many sensors that influence the computer's decision-making process.

Your best bet is to find an online forum for your truck. Since it's such a popular vehicle, there's likely to be many forums ... with other people who have encountered similar problems, and solved them. A factory service manual also may help to troubleshoot electrical problems.

I have a 1986 Cavalcade that runs great then without warning stalls out. I think the fuel pump relay is bad. Does anyone know where this relay is located on this bike?? Thanks

Does it stall suddenly...or start sputtering as if its running out of fuel. The fuel pump stopping shouldn't kill the engine suddenly....each carb will empty and you will lose one cylinder, then two etc.
If its dying suddenly I would investigate your sidestand switch....when the bike you ever find the starter won't immediately crank?

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

Trans Sport 1998 fuel problem

What you just did is most of the test. Just check that there is power at the pump. If so, change it (don't forget the filter) Problem is common to most if not all electric pumps.
