94 gmc sierra wont start

[Brndncrlsn]

I just got a 94 gmc sierra and it was dead when i got it so i got a new battery and it started right up then i put the dadh back in it because it was out and two days after that it stopped running and would only start if it was connected to jumper cables now it wont start at all. Anyone have any idea what might be the problem? Let me know thanks

I'm assuming you meant put the dash back in? (dadh? dash?) and if so, then chances are its something electrical.. i'd check fuses first of course but it might be worth taking the dash back out, check all the connections and wiring, it could be shorting out anywhere. I hate electrical, so I wish you the best of luck with it.
