Msd distributor cap problems.
Since then i reinstalled it and haven t had any problems yet.
The most popular msd distributor is our standard pro billet model.
The warranty on it was expired so that was making me think it was a common problem with these.

Disconnect the msd magnetic pickup connector from the distributor.
Remove the coil wire from the distributor cap and position the terminal so it is approximately 1 2 from a good ground.
I do keep my stock distributor and the proper size wrench for the hold down bolt in the car just.
Engine misfires can occur for a number of reasons.
Usually a faulty distributor rotor and cap will produce a few symptoms that alert the driver that service may be required.
After having this setup for two years it was running extremely rough on idle.
To clean it up i used flat head screw driver or sandpaper.
If you are using the 2 pin magnetic pickup of the msd to trigger the ignition follow these steps.
My truck has developed an intermittent although increasingly common heavy backfire.
So he pulled the msd electronic distributor from the old motor and stuck it in.
I m having the same problems on my pro billet distributor seems like i need to change the cap and rotor every year and this is only a summertime fun car half the year it s hibernating.
Have had to replace in mid season before.
He s got a gm crate motor in his 37 plymouth came with an hei that wouldn t fit against the firewall.
Posting this for my brother.
Msd distributor cap failures was.
I have a old msd cap and it is seems to be far better quality than the new ones.
Every 500 miles i have a heavy oxidation carbon or however you call it build up at the distributor cap inside contacts as well as at the distributor rotor contact.
Checking your distributor rotor and cap to see if they need to be replaced is one way to ensure that everything is in solid working order.
I sent it back to msd and they replaced all the guts including the module free of charge.
This sounds much like a the firing order being wrong.
This is easily identified by a 2 pin connector with one violet black wire and one orange black wire that connect to the magnetic pickup inside the distributor.
