This is how to do a proper explanatory video for those newbies in Auto electrics. Thanks for this. Thumbs up .

[@MrDidrill]

Thanks for the comment

[@tomtricot1430]

best video on this yet. simple, straightforward, directly answers question. Thanks

[@MrDidrill]

Thanks for the comment. Makes editing worthwhile.

[@elvismanrocks]

I agree!!!

[@joggerman1234]

Best video on this topic. After watching so many guys waste time. First, it's 5 minutes of "please like my channel" Then it's 2 mins of similar relays and situations Then it's 1 minute of scrounging around And finally 30 seconds of the content I needed. You are old school cool my friend.

[@MrDidrill]

Thank you so much for the comments. You are right on target. if I ask what time it is, don’t tell me how the clock works first.

[@aletheiaquest]

Very good instructions. You clearly thought about being the other person watching your video who may not understand this at all. Well done.

[@MrDidrill]

Thanks for the comment

[@MA-si6lx]

Excellent clear description of all parts of the relay. This enabled me to identify the prongs on the relay I am testing. TY. Mark

[@MrDidrill]

Thanks for the comment. Glad it helped you

[@Engineerboy100]

Good job on the video, thanks for posting, nice and clear and simple.

[@MrDidrill]

Thanks for the time to post a message. I am glad you liked it.

[@heatherowenby3862]

Great video!!! They make cars more and more difficult to work on! I miss my 1966 Mustang it was so easy for me to work on,lol The newer cars I am lost! Your video is very helpful :)

[@MrDidrill]

1966 mustang is still a great car.

[@petrosaguilar8916]

90's cars are simple compared to today's vehicles.

[@JAlex-ng1mu]

Thank you. I like the still shots showing exactly what you're talking about.

[@MrDidrill]

Thank you for the comment.

[@millyc.7925]

very good job, was surprised to see any dislikes for your teaching moment here.. goes to show cant please everyone, great job & keep up the very helpful/informative videos..thank you for you help

[@MrDidrill]

Thanks for the comment, as it is very enlightening to read.

[@rodneybeliso3242]

You have the best detailed instructions I've seen. Thanks for your video.

[@MrDidrill]

I am glad that you enjoyed it, and thank you so much for the comment.

[@douglasolsen1208]

Thanks for the video about this. I had not checked the relay and was looking at a fuel pump replacement. Sadly, the relay checked out OK and I am still looking at a pump replacement,. Even so, knowing the relay will not turn out to be the culprit after the pump is replaced is worth a lot. Thanks again.

[@MrDidrill]

get a new fuel pump online for as low as $20 at carparts.com, or rockauto.com Alternatively, if you do not have an access door,you do not need to drop your tank. You can make your own access door with a hammer and chisel, grinder, nibbler, saws all, etc., but first look at some videos on how to do it safely kzbin.info/www/bejne/b2qpla2bd7WhpMk and kzbin.info/www/bejne/eYCyfZiprs6JhMU and kzbin.info/www/bejne/f3_RY355eNeJisk

[@elvismanrocks]

Simple and easy that's the way everyone should do their videos Thank you!!!!

[@MrDidrill]

Thanks for the comment.

[@Dave-mf5fv]

Nice Info. appreciate it, Have a crank no start on our 2000 wagon dohc 3.0, and your video helps out alot, at least I won't throw parts at it, but in the end believe it's the FP.

[@MrDidrill]

Dave Nevotti There are 2 relays that control the fuel pump. On my 98 Taurus it was the 2 on the top right side looking from the front of the car. you might also try to jump start the car, as more current will sometimes start it. If it does start with a jump, then your fuel pump needs to be changed.

[@MrDidrill]

Please click on "thumbs up", if you liked the video.

[@brickinthewall8752]

just dx'd my car with this video! new relay for 15 bucks and im back on the road. great vid!

[@MrDidrill]

glad to here that the video helped you.

[@alexg8849]

very well explained! Your video just saved me from dropping the tank in my car. Thanks!

[@MrDidrill]

I am glad that you found my video, and in case you do need to change your fuel pump in the future, and your car does not have an access door to the fuel pump under the back seat, then you can make your own access door with a hammer and chisel, grinder, nibbler, saws all, etc., but first look at some videos on how to do it safely kzbin.info/www/bejne/b2qpla2bd7WhpMk and kzbin.info/www/bejne/eYCyfZiprs6JhMU and kzbin.info/www/bejne/f3_RY355eNeJisk Also I have found the cheapest price to be at carparts.com where I got one for a 1998 Ford Taurus for only $16 (list price was listed at $173). Quite a bargain. I always try there first when price checking for anything automotive.

[@juandoe4953]

You sir are fantastic. Quick and to the point. 👍

[@MrDidrill]

I appreciate the comment.

[@billpenn7492]

Great easy test thanks you explained it very well. If your stuck on the road ,you can swap out relay with one off the others to get you going THANKS BILL PENN Phila PA

[@MrDidrill]

Swapping out is good sound advice, thanks for the post.

[@charleslindley1596]

Very good.Just what I needed

[@MrDidrill]

Glad it helped you. I have to watch it myself, when needed, because I just forget after a while.

[@jerryrodriguez6263]

Very well put clear and concise thank you

[@MrDidrill]

Thank you so much for the comment

[@camomanofcranham]

thanks never done this test, its been a great help...

[@MrDidrill]

I am pleased that it has been of help

[@jfarinacci0329]

Good explanation. Thank you.

[@MrDidrill]

You are welcome! and thanks for the comment

[@alanspicertelecom]

Thanks for the video. I was going to swap relays in a 2001 Ford Taurus - and I thought I tried once to take out the Fuel Pump relay. I broke a plastic tab. After seeing your video I got more brave because you seemed to just grab it from the sides and pulled it right out. So I did too. Tested it with Bench 12v Power Supply just like you showed and it clicks and gives good continuity between the right other 2 pins. Still don't know why car won't start sometimes ... but now beginning to suspect fuel pump ... or connections on the actual fuel pump. Seems to favor having more gas in the tank. For awhile it had trouble at 1/4 tank. Now it seems to have trouble at or below 1/2 tank. Used to just leave me stuck somewhere - spitting and sputtering and not starting, to start 1/2 hour later. To now sometimes not starting on Cold Start after being parked all night long. I hate the prospect of paying over $400 for the mechanic shop to drop the tank and fix it by fixing connections or replacing the pump.

[@MrDidrill]

Alan Spicer Sounds like the fuel pump just go weaker and weaker. When it starts after a 1/2 hour it is your fuel pump armature cooling off and contracting enough to make a connection again. When it does not start when it is cold, sometimes a battery jump will give it enough extra electric juice to kick the fuel pump on. Sounds like a new fuel pump is over due. I got one for my 98 taurus for $10 at @qzq9stz an changed it out myself. You need to take the gas tank off to change it.

[@MrDidrill]

Alan Spicer I'll try that link again. if it does not work this time, it is in the next comment down below this one@qzq9stz

[@alanspicertelecom]

I had my fuel pump replaced and the external fuel filter. Both were original from 2001. Now it starts just fine everywhere I go.

[@reddrw1]

The explanation was simple ..Thanks....enjoyed it

[@MrDidrill]

Thanks for the comment.

[@petrosaguilar8916]

I am working on a '98 Taurus wagon. I have found the relay to be good and there is power going to it. I have removed the fuel filter and turned the ignition key and there is no fuel being pumped. Is it safe is call the fuel pump bad so I don't drop the tank for nothing? Fuel inertia switch is pressed in.

[@MrDidrill]

Instead of dropping the fuel tank, you might want to cut an access hole in the floor board above the pump. That is much easier, and quicker. There are several videos on youtube, about ways to do that, but if you can;t find one, I would be glad to link to a few if you wish.

[@badass98kx250]

awesome video your videos help out so mich thank you good sir

[@MrDidrill]

Thanks for the comment.

[@MG38601]

Good video. Could you just swap the AC relay with the Fuel pump relay, and turn the key to listen to see if you can hear the fuel pump come on?

[@MrDidrill]

you can swap it with any other identical relay, like air, horn, lights, etc. You can also check it be putting the pump relay, into one of the others, and see if they still work

[@windycityben4850]

Great explanation

[@MrDidrill]

Thank You

[@edwardquintana7281]

I have a 2000 taurus 3.0. Is there a cover over the fuel pump for easy access to replace it without having to drop the tank? If so is it in the trunk or under the back seat? Thank you!

[@MrDidrill]

Edward Quintana Than would be nice, but it does not exist. If you decide to do it yourself and save $300-$400, you can buy a new fuel pump cheap at the following online parts store. I bought one for a 1998 Taurus for under $11 and with shipping only paid less than $17 using the following link tinyurl.com/qzq9stz - Good luck

[@Mustangladyme]

No you have to drop the tank unfortunately.

[@MrDidrill]

You can make your own access door with a hammer and chisel, grinder, nibbler, saws all, etc., but first look at some videos on how to do it safely kzbin.info/www/bejne/b2qpla2bd7WhpMk and kzbin.info/www/bejne/eYCyfZiprs6JhMU and kzbin.info/www/bejne/f3_RY355eNeJisk

[@riccosuave1975]

Great video, got to the point. Thank you.

[@MrDidrill]

Thanks for the comment.

[@CannabisStocksAnalysis]

Thanks. Interesting. I'll test mine now

[@MrDidrill]

Thanks for the comment

[@tfurin30]

Do all 5-pin fuel relays work the same?

[@MrDidrill]

I think that they are similar, but different makers have different designs.

[@dimplelau5401]

Thank you! I have a mains powered charger for a 12V battery, can I use the charger to energize the relay?

[@MrDidrill]

I am not sure what you want to do with the relay. Are you wanting to test a relay? If so, check out my video on testing relays kzbin.info/www/bejne/qXOoaJiGaM19h7s

[@MrDidrill]

Sorry, I just noticed that you were looking at that video. Yes, anything will activate the relay, even a 9-volt battery.

[@dimplelau5401]

Thank you very much for replying so quickly, I really appreciate it. I look forward testing the relays using the information you have provided. Hopefully will save me taking it into the garage if it's just a bad relay causing my latest car troubles.

[@MrDidrill]

You can also just switch the relay, with another one that you know is working. like the headlight relay. Also, in some cars, there are two relays that control the fuel pump.

[@DrPGnGM]

Great video! Thanks man, helped a lot.

[@MrDidrill]

Thanks for the comment

[@terrymiller9763]

1st thank u for the video and i have a question. When measuring 3 to 5 it jumps and then rests at 0.00 is that ok?

[@MrDidrill]

Test with another to see If the same thing happened

[@carlosgraphic]

if it reads 0.04 or 0.03 Ohms, are they still good?

[@MrDidrill]

You should have more that one of the same type relay, so see how the others read, or simply switch it out with one that works, like the horn, or light relay

[@loganpitts7037]

Yes finally someone not trying to hear themselves ramble on nice work. K.i.s.s.

[@MrDidrill]

Thanks for the comment and I hope the video has helped you.

[@loganpitts7037]

Not really i made my first tesla coil when i was 11 but my non mechanical inclined friend was amazed. Not magic just magnet

[@MrDidrill]

Tesla had some interesting projects..

[@lesleyramsey7789]

Can the check engine light come on if it is a bad relay?

[@MrDidrill]

If you have a bad fuel pump relay, you will not be able to start the car, so the light will not go on.

[@robertpc100]

where is the relays on a 1991 mercury sable.my fan runs all the time and car act normal at times then acts like it isnt gettin gas.i replaced fuel filter and did tune up.pls hel;p.pob

[@JM-ue5gj]

Can you tell me where I should look if the relay does NOT click? I have put different ones in and a new one but still no Clcik.

[@MrDidrill]

If the relay does not click using the procedure in the video, while out of the car, then it is bad. If it clicks out of the car, but does not work when plugged in, then you have a connection problem

[@JM-ue5gj]

Hi Mr DiDrill, okay. I am going to try to test it again after watching the video again. I cannot find a spot on fuel rail to test psi. It is a 2003 Explorer Sport XLT 4.0 SOHC built 12/02 I do not know if it has fuel psi regulator or if that is in pump/tank. Any help on how to test fuse block as a whole both inside and out would be great. Also, I want to try to check grounds. But I cannot find how they run through to back. I also do not think trailer light attachment has power/ground not sure which but I couldnt get test light to light. So I was thinking a short or not grounded or broken wire? Thanks so much

[@MrDidrill]

you can see a picture of the location of the fuel rail schrader valve at www.explorerforum.com/forums/index.php?threads/fuel-pressure-101-mini-diary-fuel-pressure-regulator-test-fuel-pump-test.142801/

[@robertorochamartinsrocha7041]

Hello. Nice video. One question? How much Ohm i should have in a fuel pump relay of a motorcycle? Thanks.

[@MrDidrill]

I do not know, but maybe the same as a car

[@andrewfagan9273]

My relay clicks when energized, but seems to hover between 16 and 24 ohms when i test resistance between 3 and 5. Is it a bad relay or no?

[@andrewfagan9273]

After getting a new relay, it does the exact same thing. So I suppose the relay was good all along. Still confused why I am reading so much resistance though

[@jerusalem4426]

Nice video good information😎✌

[@MrDidrill]

Thanks for the comment

[@Keeping-It-Real-55]

Thanks for the video it helped!! :) I tested my fuel pump relay the same was as you did in the video. Of course I get the click meaning the relay is working. But when I tested the ohms from pin 3 to 5 I got 0.00. I tried it several times to see if I would get 0.01 or any other reading. Does that still mean its good? I am testing a fuel pump relay on a 99 Ford Ranger. The relay's are identical.

[@MrDidrill]

Could have been that the tester was set for a reading too high. It is also good to just switch the relay out with one of the other ones.

[@GaniBebri98]

Very thorough

[@MrDidrill]

Thank you, I hope it helped.

[@AstroBananna]

Will leaving the relay energised for too long melt it down

[@MrDidrill]

It is basically just an electro magnetic switch.

[@greengrow2367]

Hey I'm havin a issue with my car when I start my car it doesn't turn in I believe it my starter relay switch its not the battery cause the car light turns on also I tryed to jump start it doesn't woke and when tryin to Start it make a clickin noses could u please help me in the right direction

[@MrDidrill]

Did you find the problem, and if you did, what was it?

[@DougHinVA]

MAKE a simple video of what to do when the car will NOT go out of PARK.... Easy and quick and can be VERY handy.

[@MrDidrill]

Depends on the situation, but it is usually caused from being in a bind, from parking on a hill.

[@JM-ue5gj]

Good info!

[@ortiztony67]

Thank you brother

[@MrDidrill]

Thanks for the comment

[@brianlindsay5972]

[@MrDidrill]

Thanks for the comment, and I think that it is great that it helped you.

[@the2ndgendodgeramspot299]

Should I set my Ohm meter to 200 or 20k ?

[@MrDidrill]

200

[@doulikepie2]

My car doesnt have a box like that under the hood. the relays are mounted on the side next to the battery. And I can't simply pull it out like that. They are connected to a bunch of wires. What do I do? I don't even know if the fuel relay is the reason why my car doesn't start and I have no way of knowing. It's driving me crazy.

[@MrDidrill]

What is the make and year of your car? The video is of a Ford.

[@doulikepie2]

It's a '93 Plymouth Grand Voyager LE. There is no fuse box under the hood, but it's underneath the steering wheel.

[@MrDidrill]

Yes, you are correct about there not being a box under the hood, however where the fuses are wired in, the replacement fuse seems to detach from the top portion by clips. If you look at a picture of the fuse, you will see. If the following link does not work for you, then go to the autozone web site, and you can find a picture of it there. Here is a link the autozone replacement fuel pump relay. www.autozone.com/electrical-and-lighting/relay-fuel-pump/plymouth/grand-voyager-2wd/1993/6-cylinders-3-3-0l-mfi-sohc

[@doulikepie2]

Thanks a bunch, but I don't have any way of knowing which one is the the fuel relay. The repair manual I have only gives general information on them and diagrams I have looked up give the wrong image. Or it simply doesn't show everything I need to see.

[@MrDidrill]

There should be 5 relays, and the fuel pump relay is the 4th one from the firewall, as seen in the following diagram. www.2carpros.com/forum/automotive_pictures/12900_fp_29.jpg I just put "1993 plymouth voyager relay location" into the Yahoo search box, and went down a few results, to the image results.

[@robertgross2947]

I also did that once with paper clips to get me home

[@MrDidrill]

Good thinking.

[@tesfay555]

What will happen if I forgot to premix my antifreeze with water,

[@darylsowers6500]

Some use 100% in their car. The danger is not having enough to protect you engine from freezing.

[@theogdirkdiggler]

thank you

[@MrDidrill]

I hope it helped your situation.

[@catdakman1273]

What the meter shows did not match what you said ???

[@MrDidrill]

Listen carefully what I meant, not what I said. I must have had too many unresolved problems in my personality structure that day.

[@Mike-fe5bq]

[@MrDidrill]

Thanks for the comment.

[@helalbouhasson3696]

Thanks alot

[@MrDidrill]

Thank you for the comment. It is very much appreciated.

[@aliefman]

My fuel pump will not shut off ever and my car won’t start since this started

[@MrDidrill]

If it does not shut off it is probably not pumping anything, as the fuel pump pressure is what turns it off.

[@jessegodinez5968]

Omg

[@MrDidrill]

Thanks for the comment

[@jessegodinez5968]

I fix my car
