65k Read first. the "now what" in the thumbnail was because I had a Brian fart 😕 Must of been a bad connection. For some reason my mind thought 6.5 ohms giving a commutator at rest sounded reasonable giving other variables~ but 65k clearly wrong 🙈 I opiligize
high resistance and wandering meter is classic sign of an open circuit, which you found to be the pump.
robinsonauto I am a Brian and when I fart it makes a noise from gas coming out my A hole and you can smell it. Sometimes a lot of smell sometimes not so bad. Never used my thumb nail or thumb at all when I fart. Not sure about my resistance oms or what my commutator even is. 65K ? how do I know I do not measure how much I walk or run. I suggest not using your thumb at Brians ass when he has a fart. It would be a punch to the face from me with no permission and that is far from likely.
brianbirc yeah I know what you mean Brian. I don't always have the best timing, however I just blame it on my girlfriend at that point
Great video hey robinsonauto I have an 2002 Buick century with a 3100 motor and I’m having this same issue motor seems fine and does start from time to time but it gives me issues sometimes far as starting and idle

,,,,,,As a 71 year old active [working] mechanic and Drag Racer,,,,,,I applaud your professionalism ,,,great video [No stinkin distractive music] ,,,just on point facts and proceedures,,,,Thank You.......
Like how you go about troubleshooting and not just replacing. That's doing it the right way and so many mechanics don't take the time or just don't know. Thanks for sharing.
I like that at key points your video overlays the wiring diagram on the screen at the same time you are doing the specific task. I can pause and see exactly what you are doing. This helps me relate what you are doing to the wiring diagram in my Haynes manual. Good job. KEEP IT UP.
I truly appreciate the fact that you used basic tools, thank you so much for taking the time.
Your pop-up color coded diagrams are very helpful to people who learn better by visual demonstrations. Thanks for making this video!
Thank you for the feedback, I'm a visual learner myself glad to hear others find it beneficial as well
@@robinsonsauto isn't it true if you constantly run low fuel in the tank, to the point the car is running out of gas, that it will burn the pump up? Great videos brother!! Thank you
I like this no-nonsense diagnosis and repair. He doesnt waste anyone's time with a lot of useless chatter and diversions.
Best crank no start video I've seen. Staring at new fuel pump, building motivation to drop my tank. Grrr. Great video!
Thank Will... That is how to verify 12VDC from a battery all the way to a fuel pump... Absolute practical video!!!
Nice job. I especially like your showing how to check stuff without a scan tool, as some of us shadetree hacks just don't have the scratch for that sort of equip. Thanks, mate. :-)
aussiebloke609 thank you! And your welcome anytime~ most of what you seen using a test light is how I would have approached this off camera as well, just a couple verification and on to the next 😉
Excellent video Will. You are one of the You Tube techs with the trifecta IMHO...#1) You are an excellent tech, #2) a great teacher and #3) an incredible editer. I put you up there with Scanner Danner, Eric O, ETCG and you know the rest. Thanks for taking the time to make these videos. You are making a difference in people's lives.
Let's not forget the most scientific tech on YT which is Matt over at Schrodingers Box and then we have Duane over at realfixesrealfast who has more experience than the names you mentioned probably combined.
I like your videos, I have watched a couple, very straightforward, logical and informational. You seem to have a bunch of people in the comments that want to throw parts at the problems they have though. One thing I would say is when I knock that ring off I try to always use brass so nothing sparks and no big booms happen. Thanks for sharing your work.
Wow... This is very thoughtful safety input... Thank to point it out... Gasoline is very flammable liquid!!!
I had a bad fuel pump on a 88 GMC truck which ran great but stopped crying shortly after. It would start sometimes & other times nothing. Eventually I found the wires going from the pump to the lines. I soldered the connection & fixed it for cc good. I had replaced everything before finding the factory loose wire connections.
I just found your channel
I really love the graphic showing the fuel pump and where the wires are going that appears
Great way to explain to a new home mechanic what you’re doing
Keep up the good work
I’m a subscriber now and I will be watching all your old stuff
Kevin Lenderman thank you for the positive feedback!! Comments like this keep me posting content 👍👍👍
Kevin Lenderman some of my older stuff is kinda well lol I let you be the judge😂 but hey we all grow along the way
robinsonsauto
Yes keep posting
Your channel will grow
You’re as good as these guys with a million subscribers by far
Great demo, Will! Gotta love how you walked us through your diagnostic thinking.
spelunkerd Hello stranger 😊glad to see you stopped by!!! Hope all is well. Glad you enjoyed
Great job Will Robinson! Nice step by step. A few basic tools and most can check this themselves! Great tip on "can you hear the pump run on key on"? no noise, probably no pump action. This older video just came up in my suggested videos. Nice to know TH-cam is suggesting them.
Good thing you checked the wiring and changed the filter, most will just drop in a fuel pump and for get about things like that and ruin a pump because of bad wiring or a clogged up fuel filter. Good Job!
Jeroen Schuuring thank you for highlighting. I agree and to be honest I was one of those people once. once! Learned my lesson fast. From that point on I replace the fuel filter at the same time! Every time.
Nice. You ask what I assume at 1:35. Based on your initial questions, he could have a bad PRE-PUMP in the tank, there are TWO Fuel pumps for that car. By the way, a lot of car-owners don;t know what " Cycling the Key" even means. I would pour fuel in the fuel injection boot, after the filter assembly, usually I just add it to the spot where the crank-case ventilator pumps blow-by into your incoming fresh air. BRILLIANT DESIGN.
I loved this video! I love watchng the testing. I would have skipped the connector at the fuel pump but I need to get in the practice of checking all of these things! LOVE IT!
Wow that vehicle looked very clean for it living up north. Another great vid Will. An as usual I’m always lookin forward forward to y’alls latest vids. Until then Chive On!!!
Thanks for your time Will. Appreciate the step by step diagnosis!
White Tiger your welcome anytime!! 👍 And thank you for the feedback
My car is doing this same SHIT!
Nice... great step by step. The added images were also a good visual addition! I'm used to 30 having power all the time (in the VW & Audi world).
Thomas EXOVCDS Hello Thomas thank for the feedback!!! It's appreciated 👍 yup seen that a couple times even faster! No Tammy needed for the step 😁💃
What’s the issue if I replace the ECu. And the check engine light flashes
Very well done Will and helpers. I can almost feel your back pain.
wysetech2000 thank you 👍👍👍do you have back issues?
Yes, Will i do have back problems.
wysetech2000 sorry to hear that
Very nice video Will and it's very nice how you're putting checkmarks and Xs to show what works and doesn't work. I was going to comment on the 64K for the fuel pump but I see someone else has already done it and that you had explained. Keep up the good work and don't work too hard! 😀👍
stuzman thank you for the kind feedback! Takes some extra effort but thought it may help someone less experienced. Yeah I slipped up pretty good there 🙈
Runs like a champ after your magic touch Will!
Ozzstar thank you!!! I Appreciate the compliment means allot bud
You are a thorough teacher. Thank you.
You're very welcome!
Including the schematics great feature! I hope your back problem resolves itself. Be careful and make sure you do not twist your torso around your feet, move the feet. Good luck.
Great work here and love the test one pin at a time for the fuel pump to work .. I had a problem when I pulled that fuse and I put it back in and now Im not getting Can through pin 85 and I was just driving it !!! But thx for the help of understanding this circuit .. So watch how you pull this fuel pump fuse and put it back in !!!
Great Job as always and you taught the owner some things as well. That's a fancy exhaust hanger lol to bad you had to cut it.
Robinson's Auto Diagnostics thank you 👍 I appreciate your feedback and support~ hopefully I didn't teach him to much 😂
Once you tested the load side of the relay you could just have gone right to the tank, supplied it voltage and called it a day there. Great video and good demonstration of all variables in the fuel pump circuit.
Evan absolutely 👍🍻 just wanted to share everything you could do prior to lifting the car digging deeper. Thanks for the feedback
WOW !!! AT 0:45. SIMILAR TO MY STORY. I FINISHED INSTALLING A FRONT WHEEL BARING, PUT ALL MY TOOLS AWAY, WENT INSIDE THE HOUSE. NEXT DAY, THE CAR BATTERY WAS DEAD. I NSTALLED A NEW ONE, CRANKED PRETTY STRONG BUT WONT START. A P1682 CODE POPS -UP, WITH; IGNITION 1 SWITCH CIRCUIT 2. AS OF TODAY, CAR STILL SLEEPING ON MY DRIVE WAY. CADILLAC SRX, 2012.
thanks for all your hard work especially in the video editing side with great graphics much appreciated, sandy
Your welcome anytime! im glad the extra effort is recognized and appreciated. thank you
Very well done video.
Love the details and the explanation on how the electrical side works and how to troubleshoot it.
Thanks again..
I was having the same issue
After i got a call from my wife saying her car wouldn't start ok so i checked it and it had a good Battery it wanted to start but wouldn't....everything on the car was working....tried jump starting it anyway still nothing i heard it all timing chain...starter...alternator and to me none of that made sense so i took off the wheel and when to work and yes indeed after taking off the belt my wife's car did start up. So i checked the ac pulley and it would not move so i took off the clutch and the bearings to the pulley fell out. The compressor did not lock up the pulley did so it prevented the belt from turning. After replacing clutch and pulley as well as the coil on the compressor everything is back working normally i hope this do help someone because it had me lost for words.
Great work Will and a thorough diagnosis. Why can't everyone put the fuel pumps under the back seat where they take five minutes to change? Cheers
Badgertronix thank you for the compliment and feedback! I always ask myself that same question 🍻☝️
" Why can't everyone put the fuel pumps under the back seat...."
Cause then my mechanic buddy would forget how to curse!
@@jackjohnson9989 and we'd all be happy folks everyday if the stealerships couldnt rob use for money with stupud designs.
You are such a great mechanic. Your depth of knowledge is amazing. I wish your workshop was in Abbotsford!
Ben Robertson thank you for the kind words and feedback bud it's greatly appreciated
2 helpers for a gas tank and a lift, boy have I been missing out :))
throttle bottle easy peasy lemon squeezy 😂😂😂
Great video and very informative. Your lady is a trooper for helping with the gas tank.
You can take 18v drill battery. And hit the fuel pump connectors, starting it like paramedic jumping a human heart.
My car started up! I tried to listen to the click noise by turning the key to the second position, I did it twice and then the car started. I wanted to record it on video to explain to my mechanic and even after unsuccessfully using an emergency battery and trying many times, it only turned on after watching the first 5 min of the video with the emergency battery connected and trying the steps I mentioned.
At 3:15, you did indeed state the obvious. You could have added fuel manually, bypassing the fuel injection computer, both fuel pumps, and at least eliminated the compression, or the spark. But, you have a big tool, one that nobody has at home. good for you.
I did enjoy this vid. Excellent troubleshooting before jumping at parts changing. Also good that you changed out fuel filter as well. Good vid
Melvin Schmecklebak thank you 👍 went a little over kill on it I realize just wanted to share a few approaches. Thanks again
You really put an effort into this video. Showing how do diagnose this issue without guessing. Nice :-)
Krille's Garage thank you for mentioning the efforts! It's good to know the extra time is recognized! Hope all is well my friend
New video is out soon, and the Smoke machine will be when I have some more energy. Thanks for asking :-)
Krille's Garage nice! Looking forward to it 👍
Another great job Will. Great information on the way you break it down. Keep up the great work sir.
thank you! i appreciate the compliment and feedback
Excellent Tip at 5:33.
Well done Will! I hope your back gets better!
I have a 1994 Chrysler Concorde that cranked fine but wouldn't fire a single time. Turns out it was the anti-theft system going bonkers and turning off the injectors. The anti theft needed to be reset for it to start. Each make is different but mine involved using the key to lock and unlock the driver side door in a certain order.
The problem would resolve itself for days/weeks before returning. The car had ALWAYS started immediately when cranked so I suspected it was something quirky. Only after a lucky internet search did I finally find that anti-theft systems often act like this.
Sorry to hear you are having back problems . :-(
Getting old is not for cowards . :-(
Seems like when you have to drop the tank , it is always 1/2 way full or more ( heavy ) . :-)
Good call and good video ! :-)
Wyr
God bless
Great vid! Its good to see you're making videos again!
TLP Zeus thank you 👍 missed you guys gets lonely in the shop 🍻
This is the best !! Thanks . Excellent teaching techniques !!
really enjoy how much work you put into your videos.
Nice teaching on how to diagnose for the DIY guys
Dude, best teaching video ever. Thank you very much. Keep on keeping on brother...
Remember on a 12 volt circuit. If it won't light a test light the circuit won't carry current.
GREG Feeney 👍👍👍 hence whey you will always see me with a test light 😉 even if I gotta build one lol I love my little 194 test light puts just enough load to pull down a week circuit~ thanks for the feedback and highlighting this
By the book diagnosis, not your typical parts changer, nice job.....
Thanks for putting out such great informative videos Will
Jeff Peterson your welcome anytime! Thank you for the feedback
great video Will. Very easy to understand. Have a good one.
hector merit thank you, appreciate the feedback
Very good video. Clear and concise.
Thank you for your videos! - PT
Thanks man just changed mine out and fixed the problem couldn’t done it with out the video
Well done - and some great teaching moments!
Good video of doing this without the fancy relay tool.
Daughters 04 cavalier "cranks, will not start," which brings me to searching for quick references and your video. Great point to point troubleshooting technique! One question: I've many cases where people swap relays from A/C to fuel pump stating "Don't really need A/C right now anyway." Doesn't the A/C help with defrosting and/or defogging the windows and air inside the cockpit? Sorry, that could be perceived as passive-aggressive because I know that it does. Just curious as to why people say that. I would appreciate your input on this subject.
Thanks! Take care of your back. No one else can.

Great diagnostic walk through.
you rock my brother. awesome video very basic breakdown of the components......
Pretty thorough! Damb good job except for how brutal you were on those relays, damb near bending the prongs in half but, i know how they are-stuborn! Great job though!!!!!
Great work guys. Thanks. I replace the relay whenever I replace a pump.
AWESOME job with the video. Question, at startup when engine is turning over and not yet running, will you be able to see gasoline flowing from the TBI injectors or only after the engine is running?
Excellent troubleshooting video!
I personally will buy a low mile used pump with also installing a brand new filter over an aftermarket new pump!
Sometimes the aftermarket pumps don’t meet the delivery ratings aside from the usual lacking of long service life!
64k ohms motor resistance doesn't jive with the 4.5 amps of current you measured. Should have been about 2.6 ohms. (R=V/I) or (R=12/4.5). Must have been a bad meter connection. But it works so.... Good work. Thanks. I thought you were going to end up with some other problem. The cranking sounds pretty bad.
Dave Sage Cheers my friend on the first to notice my blooper 🍻😊 I screwed up yes. that should have been a red flag! I almost removed that test during editing than thought no I will be honest and show my slip up, the "now what" in the thumbnail was because of this 😕 Must of been a bad connection. For some reason my mind thought 6.5 ohms giving a commutator at rest sounded reasonable giving other variables~ but 65k clearly wrong 🙈thanks again for the feedback
while you have the tank out just cut an access hole in the trunk for the next time- what i did on my 02 mustang- pump was $11
Make sure you get an upgrade for your test light....It involves a bench grinder and safety glasses. If done correctly, you can poke holes in wires all day long, LOL. I feel more manly when I use my violet test light, it matches the carpet...
That's funny. I was going to watch this video earlier but then I saw Spanky on like and well...she's better looking than you. LOL Now on with your video before she comes back. She's a hoot with those kids. Man your editing is great!
wyattoneable hahah😂 I don't blame you for that one 🍻she's truly is a great person. Thank you for the compliment
This is why I keep you two around! ;) HAHAHAHAHA
(Ha Ha) We're going to get along just fine. :)
Family team work!!!!
Excellent video. Step by step explanation, super. Thanks.
That's some pretty fancy special effects!
drm315 🥂with hopes the visuals will help~ I'm a visual person as well
I have a 2010 Tucson and I changed out the spark plugs and the ignition coils still crank but no start I got my crank shaft sensor in and i'm gonna try that after that I don't know already checked fuses and I have a new battery
What was it ?
Is it me or does it sound like it has low compression in one of the cylinders?
Bad Drivers of North Texas after reviewing the video I agree it's not just you, not sure why it came through like this I didn't catch it in person however no don't it absolutely sounds like a week cylinder. No missfire smooth idle after start up
Great video .I check my 02 Malibu and the pump wouldn't run. I checked my car as you showed and must have had a bad connection at the block on back .The pump kicked on then off . I had to solder a 2.2k resistor to b the pass lock and got it running as the pump ran then the pass lock shut out off.I drove the Malibu today a few miles and it died in my driveway.I don't hear the pump.Kinda think it may have went
Perfect job man ! another one down ..
ShawnMrFixitlee thank you bud 👍
CHECK IGNITION SWITCH. MINE SAT UP. STARTER CRANKED BUT NO
IGNITION. SPRAYED IGNITION SWITCH AND FREED UP ASSEMBLY.
ALL IS GOOD NOW. BUT DO NOT OVERLOOK KEY SWITCH & ASSEMBLY.
$200 cheaper, with reviews that say works fine, means it will work fine for a few days to weeks then quit again :))
throttle bottle that probably sums it up well lol
Hi it hi hi hi hi
My car has the same problem but u can hear the fuel pump so mine is electric problem we tested alltenator it passed 3 times did spark plugs. It destroyed 2 batteries even a brand new battery
Thanks for the video, well put together
i own a 1986 cutlass supreme. after its been sittin too long in the cold it cranks but it dont start....UNLESS i hit the gas pedal a couple times and rev it. sometimes i have to keep my foot on the gas to keep it from cutting off until it has enough juice to stay running.
Another great video mate sorted job done customer happy
bodgit and leggit garage thank you Leon, its been a week or so must be ok sweet!
your gonna sack steven as Will gets the customer to help out lol
Sorted!
Great video, awesome detail.
I recently bought a mustang 06, it runs perfectly. Then after a month, one morning it didn't want to start anymore, i already replaced the fuel pump
Now I don't know what to do
Thank You I am pretty sure I going to have to change my Fuel pump on 2008 Pontiac G-6
Thanks for those tips.
You. Should check the baffel make sure its secured to the bottom of the tank had one that everytime went over a bump baffel hit pump and killed it. Took it to all the mechanics they changed all the injectors it still did it until i found the baffel broke loose
You have to look at the fuses and wiring that is probably the most common issue
I have a similar problem with my 2004 sunfire but i can hear the pump. Sometimes it will start and work just fine. I have a new battery and new spark plugs too
Muy eficiente tu explicación.. Agradecemos sobre manera, esa enseñanza .Muchas Bendiciones..
Thank you very much! Mr. Robinsons. Like! Of course
I have a 2000 Monte Carlo 3.4L and it has the same problem but I don’t think I’m getting spark. I’ve replaced the fuel pump, the fuel pump relay, the ignition control module. Still nothing. My fuel pump doesn’t cut on either even tho it’s brand new.
Fuel pump FTW!
Outstanding video!
I have the same car, right before Christmas it didn't start for almost a week it would crank, I got it to start once in that week but when it started it shook sputtered and cut out, this was at just below half a tank, I was trying to leave work yesterday and it wouldnt start at just under half a tank, it cranks but the more a try to crank it the worse the crank sounds, what does it sound like is causeing because everyone who I know doesn't actually know shit about cars tells me it's the starter but I am not convinced.
My cavalier needed a ignition switch. $21 on ebey.
