Fuel Pump Relay TESTING and REPLACEMENT

[@PeaceBWithU101]

Best tutorial of relay testing...period.

[@ericrodrigue893]

Worked to check my snowmobile relays! Thank you!

[@ernestomartinez7910]

Great explanation and detailed and obviously it’s not for my car but you did mention that all you would have to do is punch in your vehicle information and the fuel pump relay so it really doesn’t matter what car you just have to punch in your information

[@HiGHnP753]

Great Video and explanation, easy and thorough style to follow and learn. Thanks!

[@mark.r8900]

Excellent tutorial. But can the relay give an intermittent problem? Thanks.

[@brianobrien]

Connecting current through 1 and 2 to get connectivity between 3 an 5, does that mean the current runs through 3 and 5 when installed? Is the relay in effect facilitating two seperate circuits that don't connect?

[@strawz007]

Very helpful, thank you from RSA👌👍

[@eltonsipes3713]

That is a good description and explanation. However a worn out relay can show good using your test, and be erratic during operation. Those relays have contacts exactly like the old points in a 1970 Briggs engine. Those contacts can become worn and burned, giving you a good indication with your meter, but can fail after having several amps going through them.

Good video tight but what kind of car your working on that would really help if I knew what kind of car is this ????

I have a 94 ford ranger with 2.3 I am not getting power to fuel pump I checked fuses under hood even the fuel shut off under dash an carper any thoughts please

[@ryans413]

Mine was a bad relay not sending the right amount of current to thepump causing it to run weak and it couldn’t build up the right pressure. New relay now pump gets its full power

[@Swahiliangift70x7]

Thank you much for showing us how to us ho to read information on the relay, how to use a multeter to test this relay and any other relay, as well as how to detect a bad relay. I really enjoyed your video. If you would do a series on how to test other electrical car parts using a multimeter I think it would be very helpful for all of us novices in KZbin Land. I love your teaching style. Will you do a video blike this on how to test a Mass Air Flow Sensor ?

Car had been starting normal without issue. Yesterday, same thing then I get on the road and it sputtered once for a split second before going back to normal. Got a few miles down the road and it started to do the same thing but more intense, like hesitation before completely dying. 94 Corolla 1.6L

[@can2266]

My RR sport 2012 fuel pump is pumping more fuel than it need while engine start. Because of much fuel, it doesnt start. Can problem be fuel pump relay?

[@cw5118]

Either that or fuel pressure regulator. Even the ignition (coil) relay can cause issues with the fuel pump if the relay is bad.

my nissan armada doesn't like to start when it's hot (80 degrees and up) outside, cranks for 3 to 5 seconds before turning the engine on. When it's cold outside (70s and below ) it cranks immediately 1 second. Does it sound like the relay?

[@cw5118]

Reading through the comments heat seems to be a factor with the relay... "park under a tree in the shade and crack the window."

You probably could but these relays tend to be inexpensive. You may save time just by replacing the faulty relay. Good luck!

If it keeps going out is it the fuel pump going bad?

[@theC0NNMAN]

how much resistance should you see passing through to consider good once the meter is hooked up? my relay clicks, but once I meter it also I get anywhere from 0.0ohms to .5ohms

[@javiertorres9666]

hello Nice video can you send the link of the Voltmeter so i can get it

[@CarsNToys]

Yes of course - amzn.to/2KOdFZD

[@PlasmaHH]

Better yet to measure the actual resistance of the relay, most multimeters beep for continuity testing at a couple of Ohms, but even a couple of Ohms relay contact resistance will drop enough voltage to make whatever is behind that act up.

It's an RC lipo battery pack. You can also use a car battery if you have an extra one.

[@michaelcochrane4417]

Where did you get it? How much do they usually cost?

[@CarsNToys]

[@Arcturian1111]

Temp fix.. If your cars interior is hot from the summer heat it can definitely effect the relay, especially if your car is old. If your car doesn't start, air your car out first and try it. It just worked for me. You can avoid car heat, by parking under a shady tree and crack the windows.

[@tunakpreston8240]

I really appreciate this man!

[@CarsNToys]

[@benc82]

Why did you do a continuity test and not a voltage test? Arent you trying to test for 12v or are you just seeing if the connection is made and that there is continuity?

[@modrarua4594]

The continuity test shows the link in the RELAY is OK and that the problem lies somewhere else, i had to think about the logic myself.

I have a ticking noise coming from my fuel relay , fuel pump is going crazy on and off , I replaced the relay nothing , I put my finger on the fuel relay and u can feel the ticks anyone know what the hell it is

[@joshjames76]

I see you answered someone's question 2 weeks ago and hope you get this. I just had my pump replaced and when I drove it home, it stalled on the ex-way again. So from my reading, it could be faulty relay: One of the first symptoms of an issue with the fuel pump relay is an engine that suddenly stalls. If the fuel pump relay has an issue while the vehicle is operating it will cut off power to the fuel pump, which will cause the engine to stall. A faulty relay may allow the vehicle to be restarted a short while later, while a completely failed relay will not. And that's exactly what its doing......The million dollar question is there a way to test for this? The towing is killing me. Thanks so much........Josh

[@CarsNToys]

Why not just replace the relay? On average, they cost $10.

[@joshjames76]

Yep that's what I did. 16.00 seemed to be the problem. I finally read an article call "Symptoms of a bad or failing fuel pump relay". Wish I had read it before the fuel pump. But its all good. Thanks for you quick reply. I was getting burnt out on being towed. Thanks

[@joshjames76]

Well its 7-31-17 and I am back to square one. I dove it home yesterday; no problems. Today I drove about 40 miles fast and slow. I pulled into a parking spot and it stalled. So keep driving and I turned and it stalled at a stop. And then again in a parking spot. Then it ran fine and I went to wash it at the end of the day and it did the exact same thing is did in the beginning. Stalled at the car wash : died. And I couldn't get it started. Tried 4 times. Nothing. Then I figured I would wash it. Then I tried again. Nothing. Then I prayed and it started and got it home, but it seemed like it struggled on the way. I am wondering what else could it be? Any ideas? Running out of money. Andy thoughts would be great. Thanks Josh

Sure could. Start by checking for spark and fuel.

That could click and you could have continuity through the contact points but what's the resistance value supposed to be. You can have a relay making like it's supposed to but if the resistance is off at the contact points it still may not work. You're almost there.

Helo, sometime there are relays with five prongs, what's the fifth one for?

[@denistuohy6420]

relays with five pins, the fifth one goes to another thing that would be powerer, when the relay is powered the pins 3 and 4 are connected but when the relay is switched off the solenoid in the relay powers down and there is no longer a connection between 3 and 4 but now between 3 and 5, its used for things like headlights, when on dipped beam the power comes from pin 4 but when on full beam the power comes from pin 5, all controlled by the switch in the car...relays with 3 pins use one of the pins as a shared earth and the other two for the circuit
