I was driving about 35 and the motor just cut out. tried to start but I wasn't getting anything on the tach and I don't know if this means anything but the wait to start light never came on. I don't have any way to read codes but is the no tach a clear sign of a bad cps? or could it still be something else? I just got it towed back to my house so I could work on it and I'm not going to work til its fixed so please help me out guys I know you can figure it out.
