Re: 88 Crown Vic - Coil had power, no spark
Take a 12 volt test light put it on the coil negative. Does the light blink when cranking the engine. If it doesn't blink check that you have 12 volt to the coil positive. If you have power and the light doesn't blink you have a bad pickup.
Ohm the wire going to the coil tower it should be appx.1/2 scale. Also check the rotor and distributor cap.
My manual shows the IDM 22ohm resister to TFI to coil. The resister will drop voltage.
Advance and Auto Zone will check the module free. I would suggest a motor craft module and pickup if needed.
The ground for the EEC-IV relay used to be located next to the computer in the drivers side kick panel.
Make sure the ground is good and the EEC-IV relay pulses when trying to start. This supplies power to the computer system.
