I set out for lunch in the Bronco today and it was kind enough to crap out in my driveway before I got down the road. The starter cranks but it does not start. A quick look under the hood told me that there is no spark to the spark plugs.
After some research and learning the components of the the TFI system and I found that there is no power to the ignition coil with the key in the run position. The little info I could find on the net leads me to think that the power to the coil pretty much comes straight from the ignition key switch but I suspect that it may go from the switch to the ICM and then to the coil.
Question - does the coil get power from a wire from the ICM? Can a bad ICM cause no power to the coil?
Thanks in advance, Mike.
