    picked up 88 4x4 suburban today for cheap. Was listed as non running, but with some persuasion it ran ok enough to make it home. If it works out good enough, then this will be Search And Rescue k-9 vehicle mostly. Which is the reason for finding 4x4, as i had my other truck stuck few times before already.
    this is the add:

    In the end it was cheaper than asking price, but there are is a lot of work to be done on this thing

    towed to the parts store:

    spark plug, transmission fluid and tv cable bracket later:

    Things noted:
    Transmission shifts at 4k rpm disregarding the tv cable adjustment
    Needs alignment and new fuel injectors
    Also rear door fails to open and stuck
    Found some hidden treasure in the back in terms of new Harley parts (carb, blinkers, foot pegs, handle bar bracket, air cleaner)

    the only thing done so far is I have managed to get the back barn door opened and lubricated the latch mechanism. Also went ahead and added bushings for the door latches on all but drivers side door as it needs a new hinge pin first. Next step will be to drop the pan and check the tv cable plunger and also pull the governor out to see if it might be bad. Additional problem still to check is the speedometer stopped working while last time driving. No any more pictures as working on it at night only for now.

    dropped the trans pan yesterday and found stuck tc plunger, freed, adjusted, cleaned the filter and put it back together including one missing pan bolt. Will go ahead and register it today and see if transmission still works.

    sent the papers in to start registration process. Injectors are flooding the engine upon start up but transmission works better now. Need to figure out if I can get the 2-3 shift firmed up in order to get less slip on the clutches. Currently TC is adjusted to shift around 2200 rpm. Some more pictures, not cleaned up yet.

    have a bit of progress on the suburban. Have 700r4 jr kit installed, changed oil/oil filter, new spark plugs, distributor cap/rotor , replace pin/bushing on driver side door hinge, new fuel filter, adjusted fuel pressure, regasket tbi, a lot of cleaning and it is now registered and inspected.

    The problem it still has, is that it will not start while cranking. It only starts on short bumps with the starter. Distributor cap and rotor helped with it not wanting to start at all when it is raining, but still in short bumps with the key only. I was able to start it before while just cranking, but it rare and takes a very long time. Wondering if anybody has any ideas. I was thinking maybe the coil or voltage to the coil while cranking, but there is definitely spark while cranking as verified that first.

    suburban as it sits now, and followed by 91 suburban that my coworker picked up recently with my help.

    Try a different 12v source for the coil.

    Sent from the dust in front of you!

    Nice work, I like the 91 too! :)

    I wonder if your ignition switch is acting up.

    That is a beefy ass rear bumper damn....

    Battery directly to the coil made no difference.

    Check power to fuel pump relay. I'll bet if you turn the key on without starting and let the pump prime. It will fire right up with the built up pressure. I'm guessing your loosing 12v to the relay during crank.

    update on the suburban. Coil was the problem. After new coil, it would start right up. But I went ahead and sold it last November because it was not 100% what I was looking for. Need to change the title of the thread to 4x4 Suburban as i had picked up 1991 V2500 Suburban to replace it over christmas.
