So this began as a simple battery change. When I changed it the alarm went off so I took out the horn fuse. Lights still flashing tried to start and it was totally dead. Did the key on the door thing and it turned over but wouldn't start. Checked fuel pump and it was getting the correct voltage but wouldnt turn on. So replaced the pump and still nothing. Finally took it to a mechanic and he diagnosed the crankshaft censon needed replacing. Said it wasn't sending a signal to the ecu or something. After 4 days and replacing the sensor, I'm told it still won't start. I thought imoblizer but the car has never used a key fob to open doors and start the car. I'm going to pick it up and have it towed to a field and give it some AR-15 THERAPY.
