I swapped a 93 explorer 4.0 into a 87 bronco 2 I am using my gen 1 dash and just the explorer engine harness... I cannot for the life of me get this thing to fire I have a new icm crank shaft position sensor is given 1 volt ac current when turning over, new coil and plugs/wires but it will NOT Spark!!! I have the big yellow wire (which I believe to be main ignition) spliced together.. I have red/lt green to red/ lt green spliced and I have black and orange to yellow/lt blue. I'm losing my mind over this.. Is there another wire I'm supposed to have spliced? I it's my daily driver and it being under the knife isn't helping me any ha ... I've searched for hours but can't find my answer I'm new to forums and don't really know how to do all this but if anyone could help me in anyway that would be a life saver thanks. I posted the pic of the guide I found and have been using if that could help

I assume the starter motor is working and "not firing" means no spark or fuel

When you turn on the key the EEC Relay should close, a "click", this sends 12volts to the Computer(EEC), fuel injectors, coil, EDIS-6 module(ICM) and the Fuel pump relay.
Check that the Coil and Fuel injectors are getting the 12volts, also EDIS-6 module, if not then EEC relay wiring is wrong or fuse is blown.
EDIS-6 module wiring here: http://www.dainst.com/info/edis/edis.html

You should also hear the fuel pump run for 2 seconds when key is turned on, EEC relay powers the Fuel Pump relay, but computer Grounds fuel pump relay to close it for those 2 seconds, fuel pump power comes from another 30amp fuse, FP fuse

EEC Relay gets this 12volts from the EEC Fuse, 30amp

Yes my bad for not being more clear. I have the fuel pump hard wired (previous owner) so I'm getting fuel no doubt I just can't get the spark plugs to fire. I have a new icm but with the icm unplugged only the first 5 or so pins are getting power the rest are not? If that's even how you test it. The crank sensor is doing what it's supposed to.. The red wire on the coil has 12v
