Hello from Ohio.I have a '98 Explorer XLT,6 cyl,4.0engine.Will a bad thermostat housing cause the vehicle not to start?I shut it off one day,and it would not start since.Hadn't been having any problem of any kind with it.It turns over okay,and you put gas pedal clear to the floor,and it will start,but,when I put it in gear it immediately dies.Can someone help us??Thanks so much....Lloyd
