    6.5 won’t start

    Alrighty so I have a 1994 k3500 with a 6.5 td that cranks but will not start. I took it into a shop to get diagnosed and they came up with the injection pump being bad and quoted me 3.5k for a repair.

    On my 1996 K3500 6.5L diesel I noticed severe dripping from under the starter. It smells and feels like diesel fuel. The fuel lines have never been changed.

    High idle switch 6.5 diesel

    I have a 6.5 diesel, I’ve seen people make high idle switches for them, but I guess they buy pins from gm(or used to) to plug the wire into the pcm. My question is, can I just make my own pin? Can I just basically push the wire in? Does anyone have a couple gm pins I can buy? I appreciate it

    Tapping into fuel line behind lift pump?

    I need to connect a 12v diesel inside of my ambulance build which is a 1996 K3500 with the 6.5. It runs on 12v and diesel fuel and has it's own fuel pump, and will only consume 0.1-0.35 liters/hour according to spec although I haven't tested that. The heater comes with a separate tank that I can...
