hi everybody my name is Eloy i have been a member of this forum for a while now but i have been MIA for a bit but im back ha ha ha.. well any way right now i am in need of som serious mechanical expertise i have a 1984 Ford Bronco full size with a 5.8L carburated pretty much stock motor as far as i know... i bought it about 2 years ago and have been pumping money in it left and right to get it going. i have replaced the whole starting system short of ignition and key because everything has burnt out or broke or worn out. the ignition swith on the column is new Icm is new, coil is new distributor cap,coil and wire are all new, starter battery and cables are new, starter solenoid is new. short of replacing the distributor for now but thats next, thinking of going to the HEI system ive heard good things so i might try it..... The issue i am having with it which kills its reliability is that when you drive it, it gets hot and when you shut it off it wont start for a long while until it gets completely cooled off. ive checked for spark every time some times ig as spark sometimes it doesn't, most times its gets fuel cuz it smells flooded (usually after cranking forever). the battery is strong.. i am at a complete loss at this point!! Any and all help will be completely appreciated.. Thank you

 

1984 Bronco 351W: Two possible types of ignition modules:

Where is the ignition module located? On the left fender inner apron (rectangular box), or attached to the distributor with torx head screws?

 

it is located on the left pro, it is brand new about a week old

 

 

it would do it since we got it. it stopped doing it so much in the winter but still did it if got too hot and after cooling off for a little while sometimes all day it would start up like nothing happened.

 

i would say at least the pickup coil in the dist. that or the HEI like you said.

 

in your opinion witch would be the better choice? i have heard good about the Hei stem

 

A couple of test suggestions. Do you still have the old module? If you do,put it in the freezer for a half hour or so and when the truck doesn't start,plug the old module in and see if it starts.
(hot won't start)Take a test light,clip it to a good ground and test negative side of coil when cranking to see if test light pulses.

Check the ohms to the pick up coil when cold and when vehicle won't start.

(hot won't start)(make sure ignition is off) If you have a good used distributor,you can ground the body with good test leads to engine,not the negative on the battery. Plug the module wire into the distributor and put the coil wire from cap and put it near a ground or use a spark tester. Caution!! Before turning on key,make sure the ground on dist. is good. Wear heavy gloves because if ground pops off while turning gear on bottom of dist.,you will get zapped. It happened to me many times. When ready,turn ignition on,turn dist gear and see if it gets sparks from coil wire. This last test would only take a couple of minutes to connect up,it's just the wording is long

 

my opinion would be the HEI but the stock ignition works good. i have a 1980 f350 with the 6.6 and still using the stock box. you might want to address the running hot thing too.

 

You sure it's not vapor locking? Make sure you don't have an inline fuel filter anywhere near the top of the motor, I've seen more than one like that causing issues. Also make sure the line from the mechanical pump to the carb is NOT touching anything on the motor, as it will eventually wear / melt and leak all over the hot engine.
