This ground that over time corrodes and needs the eyelet replaced is under the left exhaust manifold near the front of the engine. Follow the negative ground from the battery down to where it meets the small ground wire that attaches to the main ground on the engine. If you look through the bottom part of the wheel well with a flashlight, you can see the 13 mm ground bolt that holds the grounds to the engine. From the top side with a 13 mm deep socket and five-inch extension on my 3/8 drive ratchet I could loosen the bolt. The bolt is short, so when loosened reach down and take it off by hand. The small, loomed wire which is short coming out of the harness is the one you need to replace the eyelet. I replaced with a shrink wrap type eyelet that makes the connection waterproof. Hope this helps with this repair.
So my 4.3 ltr is a little different and i only have one coil on the passenger side right next to my icm, do you know where it is? My truck has been sitting for 3 months
Dude, you rock. I am no novice when it comes to diagnostics, but this issue kicked my butt. I never thought that it would lose ground with key on! That's some funky stuff lol. Thanks for sharing this, you've helped a lot of people
You saved my day. My 2005 Chevy truck did the same thing. I was getting ready to haul in for junk price and ran across your video trying to find out why it just quit. Thanks for posting. 5 minute fix and good to go.
I want to give you a BIG shout out, you are a God send. We are financially broke and couldn't figure out what was wrong. Watched your vid ,even though was lil worried, we were like what do we have to lose. In about 10-15 min your trick worked on our, 04' Chevy avalanche. Thank you very much ❤
Dude I can't thank you enough for the help! I have an 04 Silverado and it's my work horse and parked it running fine then went to start it and just cranked and cranked. NO SPARK, GOOD FUEL PRESSURE I was stumped for several hours came across this video did exactly what you said and BOOM back in business!!!
You are a gift from God my brotha! My truck has been sitting more than 2 months not knowing what was wrong with it. I replaced the fuel pump, maf, map, crank position, camshaft position sensors and none of them seem to work until I came across your video!! Thanks brotha!
You my friend are the man! I've been scratching my head and motherfing everything. Did this and solved my problem, spent $500 in parts today and still nothing until I replaced this ground, thank you!!
Bro thank you so much for this video,me and a buddy was in his Tahoe when it just died on the high way and while waiting for a tow I came across this video and bang I fixed it til we got to the nearest part store and she’s been running great since! Thanks again bro!💯🙏🏽
Just tried this on my 2004 z71 Tahoe and it fired right up. I been through so many new parts and even a whole column assembly and didn’t get any results until I tried this! Thanks a million!
Dude… this solved our problem with 2004 5.3 reg fuel. He had no 5v signal coming from the ecu to all the coil packs… cranks, but no spark. changed crank, cam sensors, coils, wires,plugs, rear o2 sensors, 1 fuel injector, had mechnics look at truck…no fix. truck got stranded and towed once… 3 weeks of this crap… and it turned out to be this exact same ground issue… note… we had to run a tap ground to both cylinder banks… no more misfires, truck run fine now. … thanks for adding the passionate explanation and the …we fixed it with an old 6ft extention cord for the tap grounds. Could have fixed this for $0 …I feel your aggravation…. This likely applies to all GM 5.3 and possibly 4.3 and others… bad GM grounds. Thanks for sharing!
