Sorry to hear about your issue. Have you tried firing it up with the ICP sensor disconnected? It sounds like you've gone through all the other "typical" parts that go bad on the 05's. If it runs, you have a bad ICP sensor and it needs replacement. If not, it rules another part out and we can proceed from there.
