Please help me guys. I’m a 17 year old with a 2003 gmc envoy. I just got it back from the shop yesterday after a motor swap. After i got it back yesterday, i installed a kenwood radio. Everything went smooth and good with that. Today after school i wanted to try and get my driver seat working. It was from a junkyard car and it worked when pulled but never worked with my vehicle. Along story short, i accidentally touched the black and orange wires under my driver seat and heard some switch/pop noises. I put the seat back on and couldn’t get it to work, oh well. But i go to start my car, and it doesn’t start. Doesn’t even turn over. Dash lights only come on in the first key position, headlights only turn on in the first key position, the radio wouldn’t turn on, the headlights would go super dim all the sudden, the headlight controls wouldn’t work, my shifter is stuck in park. I did get it to start after holding it in the start position for a few seconds, and i went to turn it off, and it kept running, even with the key out. It wasn’t really a smooth idle though. It was really rough, like it was about to stall. Please help me guys. I don’t know where to start and my step dad is going off to drill. I just dropped $1200 on a new engine and i don’t want to wait longer without a 4x4 vehicle in minnesota. Thanks.
