I have an 87' F-250 w/ L6 300, fuel injection. Here is what I have checked so far guys. Battery-good crancks fine, fuel fine, NO SPARK FROM COIL. I tested all wires to coil and I have 12v to the coil from battery when the ignition is in the on position all the way to the distributer cap. When I crank it over though the green wire from the coil connector (the single wire on the bumper side) to the eec module goes from 12v to 0v. Could it be a bad module and if so where is it located so I can test it? This has me frustrated because I parked the truck 5 weeks ago and it was running great then. No warning signs of this. Thanks for any ideas!!

I finaly figured it out! It was a rotton wire from the ignition switch to the
TFI module.
