You have a bad connection. Use a volt meter and trace it back until you find the correct voltage, the thing you just went past is the problem. If the voltage across the relay contacts is more then about 0.7 volats replace it.

SOURCE: 1999 Honda Accord won't start. No fuel pressure,

The relay may be located in the under hood fuse/relay box.
Check your manual for the location of the relay, if listed.
Check for a sticker on the inside of the under hood fuse/relay box for a possible guide.

I have a 1988 ford f150 and have non power to the fuel pump

Sounds like the relay has gone bad (common problem on these trucks) there is no rebuild so you have to replace it (around $10) located under hood, passenger side, by air cleaner you'll see a bank of little "boxes" the fuel pump is the green one. Just go to your local parts store to get the replacement. You just unplug the old one, and plug in the new one. Do make sure the key is OFF when you do it.

My fuel pump is noise.

does the starter turn the engine good?If it is draging or clicks a lot(the starter)it may have low battery voltage.Replace the fuel pump relay,and if that does not fix the fuel pump problem,replace the pump,checking the fuel pump pressure is the thing to do before replacing it.See if fuel is getting o the injectors,if it is,the problem is in the crankshaft sensor.This is where the injectors get there pulse.

2004 Sunfire Problem starting and shutting down on occasion

I'd want to check voltage and ground for fuel pump relay. The load side of relay is the line with arrowhead, when relay is energized that line with arrowhead moves to other terminal and sends voltage to fuel pump on gray wire. The control side of relay is that coil symbol, it has to have voltage and ground, the voltage comes from pcm, the ground is a chassis ground. The voltage for load side of relay is fuse protected, fp/inj fuse. fuel pump-mo2osvehtzbwzhstuaetpz2s-2-0.jpg

check for voltage at the pump. If it has 12v there, (and a good ground) then pump is bad. there may be a pump fuse on the fuse block (can't remember) but if you find it has blown, the pump may be getting ready to fail. If fuse fixes the problem, replace it and carry an extra with you, then change the pump.

Fuel pump non functioning

Hi. here are a few steps that will help you troubleshoot this device.

Step1 Go to the back of your carand take off the fuel filler cap. Ask an assistant to turn the ignitionon but do not start the engine. Listen closely for a brief, vibratorysound coming from the tank. If you cannot hear the sound, go to thenext step. Step2Check the fuel pump circuit fuse. It should be in the fuse panel underthe dashboard or in the engine compartment Verify that it is in goodcondition and the contacts are free from corrosion. If necessary,replace it and test the pump again. Step3Inspect fuel lines, hoses and connectors. Make sure hoses are not torn,bent or obstructed. Verify there are no gas leaks. Step4Locate the fuel pump relay. You might find it in the enginecompartment, at the driver or passenger side and close to thewindshield or at the front of the engine as part of a cluster ofrelays. Another common place is under the dashboard. Step5Remove the fuel pump relay. Ask an assistant to turn the ignition onbut do not start the engine. Using a test light, check for incomingvoltage at the relay connector. If there is no voltage, check for anopen or short at the wire between the relay and the fuse panel. Step6Jump the relay connector to apply battery voltage to the fuel pump.After the jumper wire is connected, ask an assistant to turn on theignition while you listen for fuel pump operation as described in step1. If the fuel pump works now, replace the relay and test again.Another alternative is to test the fuel pump relay for properoperation. Step7Locate the fuel pump connector at the back of the car and check forincoming voltage with a test light. While you check for voltage, ask anassistant to turn on the ignition but do not start the engine. If thereis no voltage, check for an open or short at the wire between the relayand the fuel pump. Step8 Check the power and ground connections at the pump and make sure they are good and free of corrosion. Step9Test the fuel pump. Apply direct voltage to the fuel pump. If youcannot easily remove the fuel pump through the trunk of your vehicle,you might want to take a fully charge car battery to the back of thecar. Raise the vehicle and secure it firmly on jack stands. Unplug thefuel connector and use a couple of jumper wires to connect the batteryto the fuel pump. If the pump does not work, replace it.

Please rate and god bless:)

1995 silverrado fuel pump relay

4.5 volts , that's not right . Resistance in the circuit . before the relay ! Do voltage drop testing , not ohms . That should stay at vehicle (battery voltage ) It should go low on the other side of the circuit . Watch this video on voltage drop . Voltage is not being pulled low , it should not not drop voltage till it goes through the relay coil , on the ground side .You have high resistance in that green with white stripe wire .
