I have a 1999 mercury grand marquis. I changed the fuel pump and fuel filter. Change plugs and coils. When i sit in park it runs but when i get on the highway after 45 sec my temp gauge will come on
and the car cuts off. Then it cranks
back up n drives after a while. The
check engine light also fades in and
out. My car was running perfect till i
changed the pump. Please help me
