help please my wife has an 05 crossfire that will not start. we had to have it towed home the other day. it has done this before and i changed the the pcm and it fixed the problem. so now the radio works windows etc but i will not crank at all no starter engagement. so now im wondering if the rcm went bad again although i did resolder the old one and still nothing. so im thinking maybe the crank sensor or ???? also can anyone tell how to check the crank sensor with basic electrical tools. thanks for the help
