Ford Aerostar XLT
Why will the engin of my 1990 Ford Aerostar not start after it has reached operating temp?
You didn't say if it stalled once the temperature got to
operating temp. I believe the 1990 Aerostar has the old style coil,
at least mind did. Sometimes when a coil goes it operates fine when
cold, but quits when it gets hot. Wotth checking.
