No. The MSD box takes the place of the Ford ignition module (duraspark II most likely).

INSTALLING HEI IGNITION AND NEED HELP


i have no issues WITH CAPS, used to have a home computer in 70s with ASR33 printing terminal that did all caps..... all the time.
Is this a 1990 jeep? and what engine? you never stated the engine
4.2 L AMC straight-6 engine?

what distributor are you running off what engine, and what year.
is it with full mech, advance and vacuum advance , pre 1986?
the nutter bypass, 4.2L
it cuts the ECU out of spark controls.

this means ECU advance is killed, on now only the dumb
module runs advance.
the stock system had a ballast resistance wire. and the
start wire to the the coil bypasses this wire. for full coil power.
this is not used in HEI.
infact there are many HEI setups. which one. 7wire. ?

here is 7
http://www.msextra.com/doc/ms1extra/MS_Extra_Hardware_Manual_files/ew7hei.gif


if i had your rig, it upgrade it to MSD. sure would. done many.
by doing that , all the mystery of parts, that works ends.
if you need help, spec out your set up, including, schematic
and BOM, parts used, p/n of parts used.

here are 3 HEI ( 4,5,7 pin)

http://brianesser.com/tech/wiring/msd/WDTN_pn9615_Page_030.jpg

The biggest issues is spark timing curves.
getting them right for those Webers.
and standalone spark controls win here.

the right way
http://www.jegs.com/p/MSD-Ignition/MSD-Ignition-Controller-for-GM-EFI-Carbureted-LS-Engines/758329/10002/-1

You tune the spark advance for YOUR engine and setup.
not that funky stock spark box and nutter mod.

my guess, is you burned up the ballast when it hit the real
inside distributor coil primary, that is totally the wrong coil
for a ballast. I hope it dont burn up a good coil,,,,,,,
The coil and all wiring for EFI must be correct
and the bypass for starting , is useless. for that distrubutor
because it runs 12v all the time, so if the ballast did stay good
the HEI would be running way too low , at 8v. running.
and would fail.
here is a great HEI page, under dev. but is good.

http://www.crankshaftcoalition.com/wiki/Hot_rodding_the_HEI_distributor

this link above shows how to get HEI right on a carb car
but fails to show the benefits of true spark advance tuning.
Great fuel economy can be attained under light loads
with large spark advance. and then less under full load.
(no pinging too)
The spark advance , allows the flame front to start at the correct time
to take advantage of piston rod angles.... and not send unburned fuel out the exhaust.
Id put an MSD in there and tune it carefully, I would. (webers a given)_

Hello! The Mad Street #8362 is not for a seven pin, computer controlled engine...It is for a five pin distributor...I believe your engine has a seven pin connector...The correct distributor is a: MSD Ignition 8555Guru...saailer

Since you are getting good spark, I would guess first that your timing is too far off. Use a timing light to check the timing since the distributor was replaced. If your timing is too far advanced or retarded it wont fire up, but do exactly as you mention. Also, be sure your firing order is correct.

Check power SUPPLY to the ignition box when the problem is happening.If supply and ground are maintained at all times,then yes,it is the ignition box.I have an MSD 6AL i bought NEW about 5 years ago...it just quit working one day.MSD said they would fix it if i shipped it to them for a min/max charge.Min like $80.....max was $150.I bought an electronic distributor,module,and wiring harness from Mopar Performance for $200 brand new.
