    2008 duramax loses all electrical when trying to start

    When the problem occurs, start shaking the battery wires, wires to the fuse box, wire to the starter. Something will show up. Try connecting a jumper cable from the battery neg to the engine block, or to the firewall. No question there is a circuit problem. Corrosion can be a real problem...

    LML Security error when attempting to start

    Some high end scanners (not one of those $29.95 readers) will reset the security system. I don't know of any way other than with one of these. Of course, there may be other problems that may be the cause of your problems, bad wiring, connectors, shorts etc.

    LML !! Stuck injector!! Any ideas

    I remember seeing a tool that 'lifts' or prys the injector out of the bore. May have been a Harbor Freight tool. Google is your friend. Maybe Youtube, also.

    LMM: Lmm no start from key

    You have proven that you have a short somewhere - the blowing fuse tells you that. Now, you just have to figure out where it is. Something is backfeeding voltage somewhere also. That may be harder to find. Get a wiring diagram to help you understand what wires connect to what wires.

    Immediate coolant pressure

    Just a WAG, clean or replace your cap on the tank. The cap lets air in and out at the appropriate time. If it's dirty, it might not work correctly. Many people just wash them with dish washing detergent, very hot water and a brush and blow them dry with compressed air.
