Not getting fire to plug wires. I have replaced coil pack, module, dist pickup,and cap. I have tested and have fire to dist but nothing coming out. This is an 86 2.8 comanche 4x4 w/ 4 barrel Holley carb and torker 2 intake. This had an 86 block but because the motor was blown we found an 88 block from an s10 chevy model and rebuilt it. The vehicle was running fine(carb,gas, dist etc) before blown motor.

If there is no spark coming from the coil, it could be the module on the side of the dist or the pickup coil inside the dist, or the coil.
The pickup tells the module when to ground the coil which makes the spark.
You may need a repair book or shop manual to get the testing procedures for each component.

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.

try changing the pickup coil in the bottom of the distributor

Bet on the ignition module,make sure the rotor is turning when you crank it.If it is suspect the module.

you said you repl dist cap that means you don't have a crank sensor you have electronic ing module. remove your elec ing module have it tested most auto parts stores could test your module, or check your coil at the neg terminal. should have power. if not you lost your primary volt from your batt.your secondary power is coming from your electronic ing module from the module to the pos terminal on the coil, when the eng cranks,from the coil to the dist cap , from the dist cap center to the rotor then out to the plugs,this all happen pervided the timing belt or timing chain is ok. the cumbustion chainber needs 3 things , thats fuel, air, and spark.

try the pickup coil in the dist at the bottom...
must pull dist to get to it and replace it
also check to see if the fuelpump comes on..
also check the oil pressure switch..

get a 20 dollar haynes or chiltons manuel and find the module and coil. always change the ignition module and coil every 4 no more than -5 years to be safe.

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.

the one that worked on this truck and replaced everything did not install the module proberly one side the hot side was not pluged up wright.when pulled dist. to replace i was able to see the problem. some people does not need to try to work on things they know nothing about. it would make it easier for those that do.

As Long As You Have No Spark, Or Fuel, Replace Ignition Module. In Might Be The Pick-Up In The Distributor, Which Means A Whole New Dist. You Can Get And Dist. With Module. Good Luck
