have replaced fuel pump. car will drive smooth for about 4 or 5 miles and will just shut off. you can wait about ten minutes and it will start again.what could be causing this?
keeps shutting off on 1997 Buick LeSabre
hello, im assuming that the vehicle has a 3.8 l engine , if the fuel pump was replaced as you stated , then it is more than likely a crank sensor .. with the car running , slightly tap on the crank sensor , if the car stumbles or stalls you found the problem .. you also might have an ignition module failing ..
Did you check the fuel filter and also the fuel tank??
