help, car won't start :(

2004 g35 coupe
It started about 3 months ago. Two coil packs shorted out on the passenger side. I went to buy used coil packs and it fixed the problem for about 1 month. Then, one of the same two coil packs shorted out again, So I replaced it again. Once I replaced it, the other one went out and completely shuts off the car. Before, when one or two of the coil packs went out, the car would still drive but would misfire. this time, it would try to crank but would not turn over. I've tested all the fuse and relays, there is fuel priming, spark plugs are new, coil packs are tested and working, oil is normal level, and most imporantly ecu is working. the only thing is it's not having any spark. I'm all out of ideas and hopefully someone could help me diagnose this problem

PS. A couple of my friends said it could be the cam sensor. I haven't had time to check test it yet.

If you keep blowing out coil packs, you may have a bad ground - have you checked all the ground connections on the wiring harness?
