I have a 92 ranger with a 3.0 and it is getting no spark have replaced the coil, the distributor, the icm, computer, and ignition switch

I am getting the pip signal to the icm bt not out i have put 3 icms on there and last one tested good before i left the store


What could this be?

 

Good read here on troubleshooting TFI system: Ford EEC-IV/TFI-IV Electronic Engine Control Troubleshooting

Print the worksheet

As a quick test you can hook up a jumper wire from battery + to the coil + then crank and see if it starts.

TFI can have a run wire and start wire, if start wire is the problem coil will have no voltage when cranking, only when key is in RUN position, so no spark when cranking
