Fuel pump is good I heard a noise when I try to start it. Fuel pump fuse under hood is good. But I checked for spark and I don't have any what do I do now

    On a distributor type system it's important to test all of the spark plug wires and the ignition cable that feeds the spark from the ignition coil do the distributor cap. Why? Here are the three main reasons why:

    To find out if some of the spark plug wires are not delivering spark.
    This would cause the engine to flood out with gasoline, thus causing a no start.

    To find out if the distributor cap is receiving Spark but isn't sending it out to the spark plugs.
    This could be caused by the cap itself or the rotor. This is a very common no start cause.

    To find out if there's No Spark at all, anywhere. If so the most likely causes are:
    The fuse that feeds power to the coil(s) is blown.
    The relay that feeds it this Power is BAD.
    The ignition module is BAD.
    The crankshaft position sensor is BAD.
