Any probs with the MSD Ready to run distributor?

[DocMel]

MSD ready to run distro with MSD 2 coil on my 440:

Lately it seems that I have had a miss that has been getting worse, erratic of where it happens, etc.  Its so bad now it has a hard start, will barely idle, and almost shuts down when I hit the accel.  Runs rough

-Plugs I changed last night.  Same symptoms:  Replaced the MSD coil.  Same issue. 
-Checked spark plug wires/boots.  Ok, no burns or arcing.
-Triple checked all wiring. 
-Distro is snug at its base.  I did turn the distro base just a little either way to see if it had worked loose:  Makes symptoms worse
-All vacum lines are snug, no leaks or breaks
-Full 12v sitting still, 13.8-higher when engine is running
-Checked plugs. Most are wet w/fuel

I'm thinking the module inside the distributor is shot:  Loss or weak spark had got to be distro related   

I'm not getting a flash on my timing light when attached, nor when plug is removed and grounded (checking for spark)  I have only checked number 1 this way, but at least 2-3 of the other plugs are wet w/fuel upon inspection

Any one have a simliar prob wth a MSD ready to run distro?

Just for sh*ts and giggles... check the engine and battery ground straps to make sure they still have a good ground connections... bad grounding can induce all kinds of gremlins! If those are good, sounds like the module in dizzy...

Also check the voltage at the distributor

Grounds/voltage are fine.   Re-sanded all grounds, it has gotten worse, as I just tried again: Now no run, but pops bad thru carb.   Has to be the distributor

Most likely the distrib unit.

replace the dist rotor?

[DocMel]

No need to. I did clean it up some just in case, as i did the inside of the cap

[cudabob496]

ok, but I've cleaned up a rotor and cap like you did, but still
a new rotor and cap ran much better.
Beats a whole new disributor.

[Strawdawg]

Assuming there are no cracks in the cap, it sounds as if the module is/has died

I have had similar issues stranding the car 400 miles from home

Try taking the coil wire out of the distributor and hold it 1/4-3/8" away from say an intake manifold bolt. Have a friend crank the engine over. See if you have a a good healthy spark output from the coil while cranking, just be careful of course.

had a friend's 16 year old get crossway with a coil, and got shocked.
two days later he died of heart failure. Ground he was standing on may
have been wet.

Had a silimular problem. The coil tested well but ran rough. Changed the coil and problem solved. Not sure why it bench tested fine but would not run well in car.

[DocMel]

Yep:  Forgot to mention I did check the original coil by grounding.   And I got a new one, no improvement.   I have ordered a new module from Summit

I just went with a msd and was going to bye the one you have and speed shop told me to stay away from them. They have had the same issues you are having with them.
