I'm working on my 93 6.5 replacing these. I discovered burned fusible links and got to wondering how all of this works. I looked in and saw the relay but it was great to look up a video showing all these tests I can do. Thanks for taking the time to make this video, I found it really helpful. Now to see what I need to do to my truck!

Driver's side was a breeze, took an hour...passenger side took three hours. I found it easier to just remove the inner fender though, without doing that i don't know how i would have gotten the two gp's closest to the firewall. Thanks again for your help with this video! you da man!

If it were me I would pull the plug wire and test that first because if that's working right you saved the time testing everything else! Good video though, i'm still searching for a 6.5

@CostcoBulkBuyer I removed the tire then the inner fender (the black one). It was way easier to do that than to struggle getting to the other plugs, especially if you have a cordless drill with a ratchet attachment, it took me all of 10-15 minutes to remove the tire and the fender. I didn't have to remove the manifolds or anything. Once you pull the fender it's real easy to get to everything. Good luck!

If the second (passenger) side post on the relay does not light up when ignition is on that for sure mean I have a bad relay? I ask because it is a new relay and if so I was sold a defective one. It's a 1998 2500 silverado.

Thank you for the videos. My 6.5 turbo glow plug light will not come on. It will start on the second crank. I guess this would be a good place to start. I checked the fuse and it is ok. Any suggestions would be appreciated.

I have an 84 K5 that was originally a 6.2 but the previous owner had a 6.5 HMMWV dropped in her. I've been running the truck on 85% WMO mixed with 15% RUG. In the past year I've melted 3 sets of glow plugs. I was told by a few mechanics that it could be because the WMO burns so hot. Also was told it could be because my timing is off. Any thoughts.

Hi! Great videos! Quick question for anyone who knows? When i test the fuseable link side of things with the test light only stays on for a second? The one on my dash stays on for its first cycle a few seconds or so i guess? So the test light, why does it only blink? Is this correct, are my plugs getting hot? With out removing them to see? Why does the test light not stay on as long as dash light? Any help much appreciated!

Hello, Thanks for the video and your time! my 6.5 1999 glow plug light on dash come on a second and truck won't start! Did test the relay and power is to it but when key on no power to the other relay side. did install a new relay controler nothing has changed. I start my truck using a wire to bring power to other side of relay holding 15 sec. and does start every time. I think glow plugs and harness are find. Can you help me please? Denis

Check the harmonic balancer and harmonic balancer pulley. The rubber insert that goes between the inner and outer part of both balancers will sometime separate or look like it is squeezing out. And look to see if the rubber has a lot of cracks in it, or dry rot. A bad harmonic balancer and or harmonic balancer pulley can lead to crank shaft failure. hope this helps

when you turn the key to activate the "WAIT TO START LIGHT" does the Lift Pump come on during that process? If so does it stay on all the time? or does it turn itself off after a few moments? Im trying to figure out if I need/want a LP pump relay harness or do I already have one? when I turn the key over it says wait to start and you hear a pumping type sound, then after a few moments it shuts off. is that normal for it shut itself of

Yes the lift pump will shut off after a few moments, then once the engine is running the pump will continue to run

At WTS, the lift pump should activate in 1996+, but it should not shut off; you should start it immediately after WTS goes out (glow plug dwell). However, if you have a LeRoy Diesel WTS harness, it might shut off at a certain pressure, but I do not think so.
