    Default Big time wiring problems? 1994 GMC 1500 truck

    so i have a 1994 GMC 1500 i picked it up the other day for $450! What a deal right? NO! but you get what you pay for ahah. Anyways the truck didnt run when i got it, I was told that it only need a starter to run which was no problem to change and it started up no problem i took it around the block a couple times i was excited ran great no problems i could feel or hear other then the terrible exhaust leak! Well then i decided to take this truck to work which is only about 2 miles away on the highway... i made it a mile what was happening was the truck started shaking at about 60 so i just let off the gas and it started shaking more finally at about 45 my drive shaft FLYS from underneath ny truck and shoots up about 4 feet into the air! The truck stalls and i pull over to the shoulder and tried to put my emergency lights on but they wouldnt work. Then all my electrical failed, my radio my lights my AC my blinkers. I knew they worked before this happened so i tried again nothing happened, so i tried starting it back up nothing no click no nothing. The next day after i got it home and everything it still didnt do anything!

    Finally i started to hold the key down and about every 10 seconds it would turn over it wouldnt start but it would turn every it started once but shut off after running for a while so i started willing the wires around under the steering columb and the battery wires everything i could see thinking maybe a wires loose or not getting conection. well after that it stopped turning over at all no battery light no check engine light the battery was still charged it was being charged the whole time any idea what this could be?

    And by the way the driveshaft is gone and the transmission may be shattered

    Sounds like you have a lot of projects on your hands in this truck.
    Since your only into the truck for a relatively small amount this might be a great time before you invest more $ to assess things and see if you could come out ahead on the deal.
    Im sure you now understand why the price was so low.
    So the tranny is a possible gonner, but you still have a good engine, r/r axle, body panels, and interior.
    About this point Id park the truck on a trailer, part out all the good stuff on craigslist, and deliver the shell to a metal recycler. End result, at least $1000 in your hot little hands.
    There are days a vehicle is worth more in parts than as a whole, Ive even bought some knowing that, and if the purchase price is right, while yours was on the high end for a scrap car theres still proffit left to be made.

    Sounds like a bad ground connection or a relay is bad and wont reset

    Well, the shaking was probably from the u-joints holding the drive-shaft. Drive-shaft have come out from under trucks before, but usually, there will be some damage. Check the back-end of the transmission for damage (cracked metal, etc).

    The vibration probably caused some electrical connections to shake loose. Check the battery terminals.
