my my car keeps cranking but won"t start . I sprayed starter in the air intake . nothing still
why won"t my car start ? on 2000 Mercury Grand Marquis
you need spark, fuel and compression. one of them is missing and you need someone to help you figure out why. most likely a fuel pump. common failure.
It may be 2 things no spark or the timing is off. check the ignition on it first the problem might be in that area.
