Man after chasing my security system for 6 hours and the stabletrak system I found your video..and yes it was the problem..thank you for your detective work..you are the man..
thank you so much for this video!!!!!! i put in 3 fuel pumps over a ground wire its been crazy....i did get all that fixed...and yesterday it woundnt start herd that clicking and just put the hood down didnt have a clue what to do....after watching this video i am ready to go fix my van.....we dont have the money to keep running to the shop every time..and you just saved us 200.00 please keep posting videos!!!!!
Thank you so very much. You saved me with this video. I took my van to a repair shop. He changed the ignition switch and didn’t solve the problem and then he told me maybe in the fuel pump but the tank was full. He said it’s too heavy he can’t drop it Till it’s empty I was calling junkyard around to junk the van. I came across this video and sure enough I looked under my van and it has the same problem with the ground strap I bought one off of Amazon for $ 7.99 and replaced it in the van good as new thank you again. You are the man.
This video helped me solve my issue! Thanks!! I have a 2007 Chevy Express 3500 Passenger Van. It would not start and found there was no fuel in the high pressure line at the engine, after checking the fuse and relay for the fuel pump which were good. I was looking for a video on how to test the electrical line to the fuel pump and found this video. The flex/mesh ground cable described in the video was badly corroded on my van at both end. Took very little effort to break completely. I ran a wire from the the driver side frame as shown in the video to the negative terminal on the battery...the van started immediately. Bought an aftermarket black/ground cable from AutoZone and connected it from the engine block to the frame to replace the broken one at the same connection points.
I followed all the same steps with a test light after assuming and changing the fuel pump. It wound up being the same ground. Thanks for fixing my headache
I swapped out the fuel pump and fuel pump relay and still no start. Watched this video and ran an 8 AWG ground from the negative battery to the frame and was all good. Thanks so much for the detailed walk through.
Good morning James. I watched and commented on this video about a year ago. Today I watched again and was able to reinforce some of the things I learned in the first time I watched. Really appreciate your methods. Whenever I have a problem I always check your videos, because I am going to get the most thorough analysis of the problem!!
Thank you. I was going to buy a new fuel pump. After crawling under the van I decided to pay to have it replaced. I watched your video and found a ground strap was off. Reinstalled it and the van fired right up. You saved me around 800 bucks.
Nice find there bro ham. I'm sure you already know this but the dim power on your light was from voltage being high on the frame while other circuit were active. Also the dim power you see on the control side of the relay (computer wire) is a bias voltage gm uses. It's super weak and would not show at all on a conventional light. hey, I have a tripod for you. One of my students just gave me one today. I'll give you my old one.
Paul your explanation was great and everything, But were you not listening to your brother? He said he could get into detail with resistance, resistance to ground and all that JUNK! It doesn't sound like he was in the mood or very interested! LOL ! And your right, two in one week? WOW ! Great vid James!
great video James. I find it very rewarding when we are able to tell the customer that its going to be an "inexpensive" fix. All because of our knowledge that we gain.
James, Thx for the vid. I cleaned the first ground and my van started. Drove 20 miles and it died again. Watched your video and found my ground to frame broke as you have shown.
Hi James. It was identical to your repair. Everyone I spoke to wanted to drop the tank. I can't thank you enough. Wish I lived close. I'm in Oakville Ontario. You would definitely be my mechanic. Thanks again.
Holy shit!! You just literally save me hundreds of dollars. Thank you brother. I ran the battery down trying different things. I was watching the video while waiting for my wife’s car to jump start the battery, still wouldn’t start ...then i saw the end of the video and I took the jumper cables off my wife’s car and connected the ground side to the frame, bam! Started right up! I was stranded so I drove it home like that. So 2002 Chevy express van quick fix if you are stranded! Run the jumper cables to your frame, negative/ black side only of course. Although.. I took the positive jumper off the battery and connected it to the fender ground and the other end to the frame as well to have 2 temporary separate grounds with no tools used. So badass
James its nice to see a professional at work. I have the same problem on my van and crawled under to find the exact same problem. Plan on changing it and I think I will be good. Thanks
Just finished up watching all of little Danner’s free content and learned a lot. But this video takes the knowledge to a quick dirty test. Very effective and cool that with what I’ve learned I knew where you was headed. Awesome!! Thanks to the Danner brothers.
just finished doing a 2007 Chevy Express that had the same exact problem and if i hadn't watched this video before i worked on it i would of went after the fuel pump, thanks a bunch for the videos.
You pegged that diagnosis! My 05 GMC’ SavanaI is doing the identical thing. wish I saw this before I replaced the fuel pump!! Same ground wire was broken. Haven’t replaced it yet. Hope it works. Thanks
You have no idea how much this sucks. I went through this today spending hours chasing down starting problems with an 08 Express van and it was this problem. NOW, I see your video. Awesome video! You would have saved me hours. I actually used a 3 foot 4 gauge cable from Autozone, with terminal ends and bolted it on.
Was this the ground from the battery to the trans that was broke? Is there 1 for the fuel pump? I get power the terminal of the fuse for the fuel pump. I don't get no power to the fuse when checked with a test light. Only the terminal under the fuse? Relay is clicking.
My dash started going wacky, the security light would come on while driving and then all the gauges would die. So I am working on the brakes and I hear that clicking noise you were talking about. I think my van has the same problem. Thanks so much for this video, what a life saver. Keep them coming, please.
+James Danner Thanks very much, i will give the grounds a look right now, but i think i am having security system issues(i have no clue how to bypass the security lockout yet, if there is one happening). i had fuel pressure, and spark, i saw spark leaking everywhere! so gave it a tune up and replaced the ignition coil as well, it would want to start but would rev up a little and die right away, now and again or nothing at all, just turning over and nothing. so i looked into an electrical plug in the steering column (for the security thing with 3 wires connected to the ignition, it seems to be free of corrosion). now i have no fuel pressure and the fuel gauge is flicking back en fourth every couple seconds.(no clicking at the relays either, so i assume there will be no power when i test them next) im at a loss and depending on UA-cam for ideas... any suggestions would be great! thanks again
Im having an unsolvable security lockout problem, the radio says "LOC" I've tried to relearn the passlock system a few times, ive done as fallows. step 1: Crank the engine let go of the key, leave the ignition on run for ten minutes.. step 2: turn the ignition off for ten seconds, then turn key on run(do not crank), wait ten minutes.. step 3: repeat step two twice(total key on run 3 times for ten minutes).. then come back and try to start...... and still no change.
very very helpful .just swapped out a pump still no go. i did clean the grounds on frame . checked fuse very dim . so i figured a ground prob. you were dead on. ground to block still connected as soon as i pulled it came apart. thanks
Glad I found your video. Have a 2012 express 3500, ended up having the exact issue, ground strap was shot. Was not something we had even thought about.
Hey James , Hope your having some good barbecue and a cold one this weekend. I got a 06 Chevy Express with a alternator cuting on and of with multiple dtcs. will check those grounds like you did. Mines not a no start but it has drivabilty issues. the fun never ends...Thanks again for your videos..
this just helped me out i was repairing so much stuff and then i find this video and that ground wire is not even attached so i just put an order in for this part.. man thanks for the vid
Damn dude! Thanks. I'm looking at a 2500 right now with the same symptoms, but intermittent. Fixies itself every time I push it inside. Been driving me nucking futs!
@@jamesdanner7850 bought this 2000 gmc safari van 4.3 it was making a noise almost like squeaky belt but wasn't got worse more gas you give it didn't even drive 50 miles shut down while driving like no gas wouldn't start back up help me lol
Why somebody would waste their time watching a video to give it a thumbs down when it's a video trying to help somebody is beyond me anyway thanks for this video great video I maintain a fleet of Vans just like this and recently had one that kept not started on job sites I would go out and play with the fuel pump relay make sure the fuse was good check all the wiring and 20 minutes later the damn thing would start I finally got it into the shop one day and was about halfway through the steps in your video when I watch this video I immediately inspected that ground cable and found it to be in worse condition than yours put a new one on and the problem completely resolved itself thanks again for a great video
It is probably mechanic stores owners who do not want the public to know the solution for a problem that would normally requires complicated diagnosis that the average Joe would not be able to figure it out on their own
Great diagnosis, James! Ohm meter would definitely be misleading in this case. Like your brother always says, loaded circuit voltage testing is the way to go :)
WOW! Not sure where to start so I will just say THANK YOU! Same exact ground strap we had broke and I heard the clicking and keep asking why Is that clicking. Our cluster did also flicker like your customer stated but we also changed the ignition module for the gauges issue but I'm sure it was the ground not the module. THANKS SO MUCH FOR YOUR VIDEO!
James Danner I was searching for the fuel pump wiring diagram and your video was in the list. I wanted to feed power to the pump to rule that out. Thanks again James!
Very helpful,replaced fuel pump, next day died on road ... watched video while waiting for tow / hauler truck. Unfortunatly I did not find faulty ground wire till after it got hauled to shop . Fuel pump associated ground , on out facing under frame was held together by a couple strands. started rite up. Thanks!
+Mark Teaford aw man. I wish I would have just shown on video that u could use a jumper cable set and hook one to battery negative and the other end to the engine or something bolted to the engine like the alternator and it would complete the ground to get u home. That's if the same ground as mine was the culprit. Glad it helped tho. Thanks
Excellent video! Most shops would immediately jump to fuel pump replacement as soon as jumper in relay contacts failed to bring fuel pump on. A little extra work paid a big dividend. A good lesson for all. Regards
thanks. how easy would it be to just call the pump since u have to pull tank just to get to the connector for testing anyway. i definitely like these kind of finds.
I owe you huge for this. Same problem on my 03 gmc 1500 awd. changed pump, filter and no joy. Felt at my wits end until i looked under and found the broken ground strap.
Hi Danner, I have to say that diagnosis was pure genius. I would have been chasing this problem tell the cows came home LOL. I've been watching your videos and your brothers videos and I'm really learning a lot from you guys. Just wanted to thank you and your brother for all the hard work your doing making these videos. Thanks again
@@jamesdanner7850I have a 2006 Chevrolet express 6.0 lq4, and the vehicle refuses to start, and when I disconnect the body ground and rub it on the body and a spark occurs, the vehicle starts What should I do ???
@Langlois-entreprise762 u could just run an extra redundant ground if u can't find the source. The oe negative battery cable goes to body and engine with another braided leg that goes to the frame. There is a harness ground that hits body under driver's frame rail near a body mount. Sometimes ill just get jumper cables and hook to battery negative and take the other back end and clamp to engine then body then frame to see which one completes the missing circuit to help pinpoint. I'm not sure which body ground u are messing with tho
I just ran into this problem. truck broke down and that clicking sound would start with the ignition in the run position. Mechanic said I need a new fuel module ( pump isnt sold by itself) the ground is definitely rotten. gonna change it and let you know, THANKS MAN!
Thank u for walking us thru the problem!! That jumper wire was a great idea and easy to do in most every diagnosis. I'll b doing it. Thanks again for sharing all that talent with us!!!
Thanks a lot. I had the same problem on my fuel pump, no ground and the fuel pump ground connected to the frame rail where it's ground is disconnected from the battery negative. I will look for the ground strap tomorrow. Thanks a lot
I must admit I probably would have put a pump in when it ran on ether, just shows you should always test, 90% of time you probably get away with it, but when you get burned its embarrassing. Great video
so u didn't watch any other videos this week? ha. seriously tho. i didn't edit anything out of this one. it wasn't too technical and I'm fumbling thru papers. just thought it may help someone someday. thanks bud
This particular fuel pump relay circuit is exactly the type(power side switched) that you would never, under any circumstances want to short to ground with the driver on as Paul would say. Cough Cough, Paul you reading this? haha. A ground that is wacky or acting goofy simple needs a better ground provided to it(running a jumper wire from battery negative to the ground in question) Now the fuel pump kicks on, bam, you are done(not with the repair, just the diagnoses) I do this with the coil side of relays too. Love bypassing things, makes me feel like a mad science. There is one thing for certain, I am no scientist, lol. Awesome video James, your local weather station could use your gnarly beard to tell their viewers which direction the wind is blowing from.
truck stuck half in driveway and half in street starting fluid gave it a little start but then nothing came in watched ur video and ran my jumper cable to battery and frame an away it went thanks for video
+phil kravitz nice! . Much cheaper than a road service call. Ha.. if yours failed like mine. You could just run a universal ground wire from something like the alternator bracket to the battery negative somehow
Ground problems can be a bitch. A lot peaple seam to get hung up chasing wires without looking at the ground points in the system. Great video that will help with lots of problems.
Nice diagnosis. I guess that test light does do more than just make noise. Interesting, that GM uses a DT relay for the fuel pump, and 87a is simply fused? Why so?
i have my daughter translate for me since she is taking spanish in high school. ha. i appreciate you watching and hope that others can learn from or at least enjoy my videos
HI James I came across your video was gion crazy thinking it was fuel pump after waching your video i had 100 % same problem i did get the click noise from abs issue same vehicle went stright to ground ..jumped ground bat. to chassi viola your the tech.thanks
we had that exact same problem at our shop. when the van was up in air, van would run. lower the van and the van would shut off. we figured some thing was losing signal when suspension was being lifted up and down. sure enough we looked under van and the braided ground strap was hanging together by a couple of strands
I'm 99.9 percent sure this is the issue I am having, same diagnosis of everything. I'm going to try the reroute of the ground like you did to see if the start. Cause my main one was also frayed an super brittle soon as I touch it crumbled to pieces.
Besides the flexibility, why order a new braided copper ground strap from the dealer at $60.00 U.S? Would it not be simple, quicker and cheaper overall to either take a bit of 4 gauge battery/welding cable and solder two female ends on? Or go to any auto parts store and buy a pre-made ground cable of the length required? 12" to 16" ??? The engine doesn't vibrate so violently to break such a cable and it would not corrode like the braided one. Of course I wrote the above prior to seeing the end of the video and that spider nest cable they sent. I guess all that for a mere $60 wasn't bad after all. However, since the part that actually failed was the copper braid strap. Just removing that part and adding a cable as I mentioned above would have sufficed. Yes? No?
come on man. i like my test light. it was broken for a few weeks til i had a chance to solder a new tip lead back to the circuit board. i should have filmed that just for u! ha. thanks man
thanks. and to be honest, Yes i would have found it. But...anyone, including me, could easily go the wrong path for a bit first. the relay is the only connection point before the plug at the pump,which is above fuel tank. and i hate piercing wires, so i could have easily wanted to drop the fuel tank to check the wires at their final destination. how tempted would anyone be to tell service writer to sell the whole fuel pump before you did that much work. or worse..u check the power and forget the ground and install new pump and it still doesn't work. i have become a little redundant with testing to avoid those scenarios as i grow in knowledge. im sure others have same or better stories. ha..thanks for watching.
This is how you diagnose a problem properly, people just don't get it and keep replacing parts. Excellent job brother.
Dude you aint lying. People will throw parts at a vehicle like crazy because they're lazy
Man after chasing my security system for 6 hours and the stabletrak system I found your video..and yes it was the problem..thank you for your detective work..you are the man..

+michael dempsey sweet. I'm glad to help
Nice find there bro ham. I'm sure you already know this but the dim power on your light was from voltage being high on the frame while other circuit were active. Also the dim power you see on the control side of the relay (computer wire) is a bias voltage gm uses. It's super weak and would not show at all on a conventional light.
hey, I have a tripod for you. One of my students just gave me one today. I'll give you my old one.
Two videos in one week? Nice!
the first one. yes .the bias voltage i didn't but have seen before and knew not to chase. thanks master paul

great video James. I find it very rewarding when we are able to tell the customer that its going to be an "inexpensive" fix. All because of our knowledge that we gain.
i do as well. especially if it was somewhere else first
Had the same problem and a 2013 Chevy van lost ground to the fuel pump could never have fixed it without this video.

What should I do ???
@Langlois-entreprise762 u could just run an extra redundant ground if u can't find the source. The oe negative battery cable goes to body and engine with another braided leg that goes to the frame. There is a harness ground that hits body under driver's frame rail near a body mount. Sometimes ill just get jumper cables and hook to battery negative and take the other back end and clamp to engine then body then frame to see which one completes the missing circuit to help pinpoint. I'm not sure which body ground u are messing with tho
@@jamesdanner7850 Je suis désolé mais j'ai du mal à comprendre votre message car je suis français
Thanks for the info, Saves me lots of repair money with your help.
hey JD just keep coming with the videos it explains to young and older techs real world deals we run across every day,keep up the good work.
I just ran into this problem. truck broke down and that clicking sound would start with the ignition in the run position. Mechanic said I need a new fuel module ( pump isnt sold by itself) the ground is definitely rotten. gonna change it and let you know, THANKS MAN!
+Jesse B u can just use a set of jumper cables from battery negative to the engine somewhere to limp it home
Thank u for walking us thru the problem!! That jumper wire was a great idea and easy to do in most every diagnosis. I'll b doing it. Thanks again for sharing all that talent with us!!!
See lots of these vans, haven't seen this problem yet though. Good video!
Thanks a lot. I had the same problem on my fuel pump, no ground and the fuel pump ground connected to the frame rail where it's ground is disconnected from the battery negative. I will look for the ground strap tomorrow. Thanks a lot
Having problems starting and this was a great upload
I'd say that's pretty sharp troubleshooting. Very professional.
I must admit I probably would have put a pump in when it ran on ether, just shows you should always test, 90% of time you probably get away with it, but when you get burned its embarrassing. Great video
same thing on my work van,it wasn't broken but real crusty.i made a new cable works great.wish i saw this video before .
What an outstanding video, James, the best I've seen all week.
so u didn't watch any other videos this week? ha. seriously tho. i didn't edit anything out of this one. it wasn't too technical and I'm fumbling thru papers. just thought it may help someone someday. thanks bud
Wow. You’re a genius to be able to trace that down.
Very thorough and great job explaining everything, thanks!
Thank you,am going recheck that ground now.preciate you👍🏽
Thank you for the video, got the van running in no time. Best wishes and thanks again, my weekend just got sooo much easier :)
+Eddie Jocionis awesome!
Thank you james! After replacing the fuel pump and a used ecu. This fixed my problem!
+Neil Roberts nice
Thank you for your knowledge, your video help me a lot, because I have the same problem
This particular fuel pump relay circuit is exactly the type(power side switched) that you would never, under any circumstances want to short to ground with the driver on as Paul would say. Cough Cough, Paul you reading this? haha. A ground that is wacky or acting goofy simple needs a better ground provided to it(running a jumper wire from battery negative to the ground in question) Now the fuel pump kicks on, bam, you are done(not with the repair, just the diagnoses) I do this with the coil side of relays too. Love bypassing things, makes me feel like a mad science. There is one thing for certain, I am no scientist, lol. Awesome video James, your local weather station could use your gnarly beard to tell their viewers which direction the wind is blowing from.
truck stuck half in driveway and half in street starting fluid gave it a little start but then nothing came in watched ur video and ran my jumper cable to battery and frame an away it went thanks for video
+phil kravitz nice! . Much cheaper than a road service call. Ha.. if yours failed like mine. You could just run a universal ground wire from something like the alternator bracket to the battery negative somehow
Best video thanks so much for it i have an o4 3500 express cutaway & had the same damn thing happening you saved the day
Ground problems can be a bitch. A lot peaple seam to get hung up chasing wires without looking at the ground points in the system. Great video that will help with lots of problems.
Great video as usual,
Thanks for the time you put into it.
Happy holidays to you and yours.
Ty so much you saved the Day....same problem
Nice diagnosis. I guess that test light does do more than just make noise. Interesting, that GM uses a DT relay for the fuel pump, and 87a is simply fused? Why so?
grasias por los videos no te olvides de nosotros los mecanicos que no sabemos mucho
i have my daughter translate for me since she is taking spanish in high school. ha. i appreciate you watching and hope that others can learn from or at least enjoy my videos
HI James I came across your video was gion crazy thinking it was fuel pump after waching your video i had 100 % same problem i did get the click noise from abs issue same vehicle went stright to ground ..jumped ground bat. to chassi viola your the tech.thanks
we had that exact same problem at our shop. when the van was up in air, van would run. lower the van and the van would shut off. we figured some thing was losing signal when suspension was being lifted up and down. sure enough we looked under van and the braided ground strap was hanging together by a couple of strands
nice. thats more weird than mine.
I'm 99.9 percent sure this is the issue I am having, same diagnosis of everything. I'm going to try the reroute of the ground like you did to see if the start. Cause my main one was also frayed an super brittle soon as I touch it crumbled to pieces.
Right on the man. Helped solve my problem. 👍
Thanks for taking your time to record
Excellent diagnosis! Tell Bob to get his own camera and get on UA-cam...and let Nick know to chill with Oreo cookies!
Man, that's awesome! Very nice! Congratulations!
Hey Man U saved my Friday today thanks
Thank you for this!! You Saved me!!!!!
Besides the flexibility, why order a new braided copper ground strap from the dealer at $60.00 U.S?
Would it not be simple, quicker and cheaper overall to either take a bit of 4 gauge battery/welding cable and solder two female ends on? Or go to any auto parts store and buy a pre-made ground cable of the length required? 12" to 16" ??? The engine doesn't vibrate so violently to break such a cable and it would not corrode like the braided one.
Of course I wrote the above prior to seeing the end of the video and that spider nest cable they sent. I guess all that for a mere $60 wasn't bad after all.
However, since the part that actually failed was the copper braid strap. Just removing that part and adding a cable as I mentioned above would have sufficed. Yes? No?
That was my problem exactly. Thanks James
Thanks a million .this was my problem after changing the relay 10xs I was lost and now I found lol
You are welcome
Great video Danner. Clarke has a great 'door mirror moustache' at 5:15!
Also, please burn that test light!!
come on man. i like my test light. it was broken for a few weeks til i had a chance to solder a new tip lead back to the circuit board. i should have filmed that just for u! ha. thanks man
You brought it back from the dead? Let it go man, let it go!!
Im gonna email u pictures of it randomly
Better then any magician ive seen nice troubleshooting man 👍🏾
Hate looking for chevy van stuff and always finding Chevy Express van stuff
Awesome info! Exact problem I had on my 2006 Chevy Express. Thanks for the insight!
Did you ever have a random misfire problem before it wouldn't start?
No misfire. Had the gauges flicker a little and then it died at a stop sign.
Thats why we call you " Boss " 👍
Thank you so much for uploading this video!
Thank you James...another great video.
Bro thanks for the helping knowledge as well as the video!
Tank you merci du Québec, Canada
Nice ! Same issue free van fixed and drove away
This video helped tremendously!!! Thank you
Nice video. Right to the point. Do you think you would have found the ground issue without the ABS system making the clicking noise?
thanks. and to be honest, Yes i would have found it. But...anyone, including me, could easily go the wrong path for a bit first. the relay is the only connection point before the plug at the pump,which is above fuel tank. and i hate piercing wires, so i could have easily wanted to drop the fuel tank to check the wires at their final destination. how tempted would anyone be to tell service writer to sell the whole fuel pump before you did that much work. or worse..u check the power and forget the ground and install new pump and it still doesn't work. i have become a little redundant with testing to avoid those scenarios as i grow in knowledge. im sure others have same or better stories. ha..thanks for watching.
Definitely a good lesson to always check power AND ground.
Great video, Thanks!
Excellent video .. thanks
Good diagnosis 👌🏻
