I have a 2001 rav4 i was driving down the road and it went to running rough then died. I towed home and found a melted coil pack i replaced it and it would turn over but would not start. I replaced all 4 coil packs and still no fireing. I checked my ecu wires coil wires and crank and cam sensor wires. All are tight and secure, i am hoping i have a lose ground wire or something may have loosened from the jerking of the misfire from the cop failure. Im not sure where to start or where the grounding points are please help.
