I dont know what "points distributor" you installed or how you made sure you installed it correctly. But a more simple way would be to get a distributor that has the coil pack built in. That kind only would require 2 wire connection. Positive 12 v and ground. also it has a 3rd connection you may use that is for the tac. very simple.
The one you have now ... do you get spark to the spark plugs. If so I would fool around more with being sure it is installed correctly, find TDC and be sure the rotor is pointing to the #1 cylinder, ALSO that you have the plug wires going in the right order on the cap. I dont think you will have luck with the computer compatible question.

I have a 96 ford bronco I took the 351 efi engine out and put a 429 thunderjet in it I was wondering how I would go about doing the engine wiring efi to basic distributor coil

Anyone can change engine with a non standard item but making it run is an entirely different problem.

Seek professional help with this. Don't even try to rig this up yourself.

Firing order for 1982 351w in f150 truck

If it's a California truck it's a good chance the ignition is EEC-III (brown grommet on ignition module.)

The EEC-III distributor rotor fires alternately from both sides of the distributor rotor.

The the spark plug wires for an EEC-III distributor will be wired counter clock-wise in a different order.

351w firing order, CCW: 1-3-7-2-6-5-4-8
351w wire order, CCW: 1-5-7-8-6-3-4-2

Need location of fuel filter on 85 full size bronco 351w engine.

If it has a carburator, the filter will be in the gas line that goes into the carburator, if it's fuel injection, filter will be under the truck on the drivers side, around the drivers door, on the inner side of the frame rail.

The "84 carburatored Bronco has only one O2 senser

block the egr valve if fitted with a full gasket made from a coca cola can that will eliminate any problems their ,then check inside the distributor cap for tracking or burning of the contacts ,also condition of the centre carbon brush and the rotor arm ,you are looking for burnt lines in the plastic where its been tracking .Now if none of this works then remove the carb place on a sheet of paper on the kitchen table and strip and clean the carb right down paying particular to looking for a grey dusty deposit .I not sure how a O2 sensor could affect the running on a carb unless its a mono point injection system ,check it out because although you think it is a carb it could be a early monopoint fuel injection system as i have never seen a O2 sensor with a carb engine but iam in europe where catalytic converters were not introduced untill 1992 ,The american car market is obsesed with emmisions but you have no yearly mechanical test of the vehicle which iam amazed about ,how many accidents are caused by badly maintained vehicles i wonder?? anyway if you keep this reply in your E mail box till you get it sorted then you get back to me for more advice and please remember the time zone difference for the answer ,

I have a 91 bronco w/ a 351w. I need to replace the ignition control module. Do I need to pull the distributor? If so, is there anything special I need to do as far as putting the distributor back in?

the ignition control modual is not in the ditributor but either atatched to the side of the distributor or located on the firewall/fender well.removing the distributor is not nessisary.

How to replace an ignition rotor to a 1988 Ford Escort

Your vehicle may be equipped with either of the following ignition systems, depending on the year and engine combination:
* 1981-82 1.3L and 1.6L engines: Dura Spark II Ignition System
* 1982-85 1.6L Non-EFI and 1986 1.9L Non-EFI engines: Thick Film Ignition I (TFI-I) System
* 1983-90 1.6L EFI and 1.9L EFI engines: Thick Film Ignition IV (TFI-IV) System

  1. Disconnect the negative battery cable.
  2. Remove the distributor from the engine.
  3. Place the distributor assembly on a workbench.
  4. Remove the two TFI ignition module retaining screws.
  5. Pull the right side of the module down the distributor mounting flange and then back up to disengage the module terminals from the connector in the distributor base. The module may then be pulled toward the flange and away from the distributor.
Do not attempt to lift the module from the mounting surface, except as explained in Step 3, as the pins will break at the distributor module connector.

To install:
  1. Coat the baseplate of the TFI ignition module uniformly with a 1 / 32 in. (0.8mm) of silicone dielectric compound WA-10 or equivalent.
  2. Position the module on the distributor base mounting flange. Carefully position the module toward the distributor bowl and engage the three connector pins securely.
  3. Install the retaining screws. Tighten to 15-35 inch lbs. (1.7-4.0 Nm), starting with the upper right screw.
  4. Install the distributor into the engine. Install the cap and wires.
  5. Reconnect the negative battery cable.
  6. Recheck the initial timing. Adjust the timing, if necessary.

Hope helps.

Can u take efi off a 302 and make it carburated

You sure can.. It would be alot of work, new intake manifold, carburetor, get rid of all the EFI wiring, PCM, get a distributor with points , unless you can find a way to use Dura-Spark ignition. You definitely will need someone who is very good mechanically. I personally would not do it.. Hope this assists you in your decision,, Cobra

Ongoing problem. On the 92 bronco with the 351w, replaced o2 sensor, idle air bypass, which was sticking, put in a msd coil, cap,wires. cleaned all the plugs again, and let the cylynders air out. replaced...

ignition module in the distributor may be breaking down!
its a common fault as they dont like getting hot!
spark plug gap is critical with these types of sytems
test each plug as you may have fractured one when fitting it

Car wont start

Its not to hard..part is about $ 50
  1. Remove the distributor cap from the distributor, and set it aside (spark plug wires still connected).
  2. Disconnect the harness connector.
  3. Remove the distributor.
  4. Remove the TFI module retaining screws.
WARNING Step 5 must be followed EXACTLY; failure to do so will result in damage to the distributor module connector pins.
  1. To disengage the TFI module's terminals from the distributor base connector, pull the right side of the module down the distributor mounting flange and then back up. Carefully pull the module toward the flange and away from the distributor.
  2. Coat the TFI module baseplate with a thin layer of silicone grease (FD7AZ-19A331-A or its equivalent).
  3. Place the TFI module on the distributor base mounting flange. Position the module assembly toward the distributor bowl and carefully engage the distributor connector pins. Install and torque the two TFI module retaining screws to 9-16 inch lbs.
  4. Install the distributor assembly.
  5. Install the distributor cap and check the engine timing.
