Do you leave distributor hooked up to factory ignition box when running a msd box

You need to contact MSD support on this, if I advise incorrectly you might destroy the new MSD ignition control

Jason, I am not sure that is the correct ignition box for your vehicle, contact MSD to see what would be best for your application. Instructions for hooking up MSD, Check the attached links,instruction and guides, Good luck

No you can only run 1 ign box at a time

NO it replaces it. Go to MSD and download the wire diagram for your application.

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

make sure to put the gasket on the distributor?

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.

a chiltons or hanyes repair book will tell u that it will run u 30 bucks at the most but it will be handy for any other problems that may come

check if the distributor is good or it could be your msd try installing stock coil and distributor.



good luck.

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.
