When I engage my key it sparks once, it doesn't spark while the engine turns over and it sparks when I let the key out. Any ideas.
Do you

Make sure the plug to the ecm is tight. THe computer sends a stronger spark when the engine is just started to help start a cold engine and then lowers the voltage when it starts and the key is in the run position.
