Hi, my car is a 1988 Mercury Cougar. It has a V8 engine in it and a 5.0 liter. My fuel pump is always on, we thought it was a relay problem and found out it wasn't the relay problem. So every night before we go to bed we have to disconnect the battery. Does anyone know what it could be?

when i put my foot on brake to start it wont do anything its not the battery is there a switch or something? the manual says to put foot on brake to start
In the Hayne's repair manual for this car it says that the lower ball joints aren't replacable and that the entire lower arm will need to be replaced! I went to 2 different auto parts stores and neither of them have the L.A. assembly BUT they both sell just the ball joints!! Am I about to waste my money by buying them??
engin will turn over but will not start
