You need to get the terms correct so everyone understands what you are telling us.

1) Crank or no crank = the starter spinning the motor over, or the starter not spinning the motor over.

2) start or no start = the engine running after the starter spins it over, or the engine does not start after the starter spins the motor over.

3) Spark or no spark = when the starter is spinning the motor over, you have a spark between the plug (or coil) wire and a ground, or while the starter is spinning the motor over, you do not have a spark between a plug (or coil) wire and a ground.

If you have no spark, spraying either into the motor will have no effect.

If the starter is still spinning the motor over after the key has been shut off, you have an electrical problem that may also be effecting the no start problem. It could be an ignition switch, or something shorting out in the wiring, or a bad relay. Gene
