Remove the coil wire from the distributor cap and position the terminal so it is approximately 1 2 from a good ground.
Msd distributor cap problems.
My truck has developed an intermittent although increasingly common heavy backfire.
The most popular msd distributor is our standard pro billet model.
So he pulled the msd electronic distributor from the old motor and stuck it in.
He s got a gm crate motor in his 37 plymouth came with an hei that wouldn t fit against the firewall.
The warranty on it was expired so that was making me think it was a common problem with these.
I have a old msd cap and it is seems to be far better quality than the new ones.
To clean it up i used flat head screw driver or sandpaper.
After having this setup for two years it was running extremely rough on idle.
Have had to replace in mid season before.
If you are using the 2 pin magnetic pickup of the msd to trigger the ignition follow these steps.
This sounds much like a the firing order being wrong.
I do keep my stock distributor and the proper size wrench for the hold down bolt in the car just.
Posting this for my brother.
Engine misfires can occur for a number of reasons.
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.
I sent it back to msd and they replaced all the guts including the module free of charge.
These distributors must be used with an msd ignition control such as a 6 series ignition or a 7 series ignition.

I have 302 engine with pro billet msd distributor msd 6al box and msd blast 3 coil.
Msd distributor cap failures was.
Since then i reinstalled it and haven t had any problems yet.
Usually a faulty distributor rotor and cap will produce a few symptoms that alert the driver that service may be required.
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.
He pulled the cap and the pickup was covered in corrosion.
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.
