So, here's the story:
Driving on interstate and I hit a bump. The car starts to buck/lose power from the engine. Within 5 minutes the car is dead on the side of the road. Turn the key: nothing. Not even the starter click. Dash, headlights, and interior lights work.
Battery was brand new. We can hook a battery up right to the starter and it tries to turn over but doesn't ignite. We tried to replace the ignition switch, still didn't start. There is voltage getting to the starter, but turning the key doesn't do anything.
We did manage to get it started and running for like 3 minutes. It killed itself- no one touched it or anything. That was with the old ignition switch.
Also worth mentioning- when we were trying to start it with the new switch there was smoke that came from the dashboard.
There is a red and yellow wire that we aren't sure what its connected to in the cluster of wires below the driver's side dash-by your feet. It looks like it runs over to the ecu though we are unsure. But, that wire gets REALLY hot when you try to start it.
The car is stranded. If anyone has any suggestions of where to start looking please share. Also, what the heck is that wire for? We are starting to think maybe something in the ECU is toast
