The ignition system on your 5.0L uses a distributor type system and will include the following components:
Ignition control module (ICM). Depending on the year of your specific Ford, it'll have a inner-fender mounted ignition control module or a distributor mounted ignition control module. hot sure which you have.
Ignition coil. you replaced it.
PIP (Profile Ignition Pickup) sensor. This is Ford's name for the crank sensor and is mounted inside the distributor. The most common name for this component is the pick up coil.
Distributor cap and rotor. you replaced
Spark plug wires. you replaced.
The thing to keep in mind about the ignition system is that all engine cylinders must get spark and the one thing that will stop the ignition system from creating spark on a wholesale scale is a BAD crank sensor.Have you pulled a plug then using some insulated pliers grounded it to the vehicle and turned it over to see if you have spark, that'll tell you alot.takes two people of course.Best of luck and hope this helps.
bet on the module,if it's tfi it's on the side of the dist.85 could be either way,may be the older fender mounted module. If it's dist. mounted Ford recomends replacing the pick up coil also. There is a wire with a plug on the tfi's ,you remove the "cap" to set the timing,just 2 wires with a gray cap on the end.Maybe that's the wire you mentioned.
This works with the 5 prong module on an HEI ignition system with the coil that is mounted on the top of dist. The wires that come out of the back of the dist go to a spark controll module under the dash and they are junk. There is a conector on the wiring harness about 5" from the dist unplug that conector and run a jumper wire from the green wire to the black wire on the dist side and make sure you tape up all wires on dist side to keep them from grounding out. On the other side of the dist where your 12V goes in (batt conection) there are to wires piggybacked on top of each other disconect them from dis and plug only the pink 1 into dist at the batt conection. Where the wires on the back of dist run into firewall there should be a vacume line disconect and plug on engine compartment side. Thats how you do the bypass and the spark control module can be removed from under the dash if you want to but its not hurting anything to leave it there. BEFORE YOU DO ANYTHING MAKE SURE YOU DISCONECT THE BATTERY. When all this is done you mite have to advance your timing 8-15 degrees. I had to advance mine 12 degrees. let me no if you have any problems. kyle yeo
replace the TFI ignition module (mounted on the outside of the distributor) and the distruibutor pickup ( inside the distributor) and the problem will go away, I would also replace the coil if it is orignal.
here are the parts you need.
UNITED IGNITION WIRE Part # M425 w/ Push-on Type Rotor-Mod. Mounts On Dist; Electronic Ignition $22.00
MOTORCRAFT Part # DU30C Distributor pick up $57.00
STANDARD MOTOR PRODUCTS Part #FD478T Ign Coil $13.00
Detach the wiring harness connector(s) from the ICM.
Remove the mounting bolts, then remove the ICM.
Position the ICM onto the inner fender apron and install the mounting bolts. Tighten the bolts to 22–31 inch lbs (2.5–3.5 Nm).
Attach the wiring harness connector(s) to the ICM.
Connect the negative battery cable.

There may be no injector pulse if the computor does not see a RPM signal. There will be no spark if the ignition module does not see a dist pulse from the dist pickup.......a RPM signal. Because you do not have both ......I would suggest to check/change the dist pick up. Follow the wires from the ignition module inside the dist to the pickup which is also inside the dist. If it is just a bad dist pickup....keep all your old parts as good spares. Also...is the dist turning? to provide a RPM signal? You will have to remove the dist to change the pick-up.....mark your timing locations......"rotor position" and "dist body location"before removal. A quick test before installing the "repaired dist" .....plug it in the the truck wiring and turn on the key....DO NOT CRANK THE ENGINE OR YOU WILL LOSE YOUR DIST ROTOR CORRECT POSITION......as you spin the dist by hand .....the injectors should spray.
if the module is on the side of the distributer it takes a wrench made just for ford modules to remove 2 screws, if you need to replace the pickup in the dist. you have to remove the dist. out of the engine pull the gear off and pull the shaft out of the dist.
