UPDATE:

this is an interesting problem,  and will write what I have learned so far.  The ignition is msd 6al with msd blaster 2 coil.  The system so far seems to be working properly. spent all day yesterday trouble shooting with no real solving the prob, but eliminated many things.

Rechecked and redid all the wiring to the coil/battery/dizzy. No shorts or mis-wiring.

If you are ever trouble shooting msd ignition NEVER take a trouble light circuit checker or volt meter to the coil's + screw and crank checking for 12 volts or power.  these coils and systems run with 0 volts in run then blast over 400 volts on the screw while cranking. I tried to test for power by doing this with a test light - BEFORE reading on website - i grounded myself and felt like i was shot with a lightning bolt!!!!!  no need to try and wire a positive from the battery direct. (like old school coils (meaning NON MSD) completely different beast here.

destroyed (melted) the light in my tester.  Was funny Angie was in the car cranking while I was holding the tester. She said she saw this flash and then me jumping around like an ape with a snake bite.

Did a check on all spark plugs with an in line lighted tester (the type were you place the tester between the plug's pointy end and the wire boot) it has a light that flickers while cranking/running. all 6 show tons of spark.

From all the reading i did last night I am thinking that I need to check for voltage from the ignition (key side) to see what it is doing. recheck the rod throw on the column ignition switch to see if maybe the whole problem is related to the alignments.

I know the car/motor is firing up and is pretty close to being in time (for not full running) she does fire up on cranking only. and still dies when the key goes back into run position.  Using a remote starter switch still gives the same problem.

last night when i closed up the shop I was amazed how much exhaust fumes I had created so from that I am fully sure she is ready to run.

cheers and any suggestions greatly needed.

thanks

I'm thinking it's tied to your ignition swith since power shuts off in the run position.
 
Here's a funny story from my learning years.....
 
When I was about 20 I had a Dodge Demon 340 with a solid lifter cam in it. I decided to adjust my valves one day & pulled the coil wire off the distributor so it wouldn't fire up.
 
It had a Mallory Pro Master coil with about a 22" coil wire on it because I had to put the massive coil on the firewall by the heater blower motor.
 
I didn't realize I had flipped the coil wire over the fender & I leaned over the fender, wrench in hand & had my buddy bump the engine with the key. Now my crotch happened to be pressing against the coil wire & it discharged right into my twig & berries.
 
I hit the wall 3 feet behind me & my head dented the drywall 6 1/2 feet above the floor & I'm only 5'6" tall. 3 feet to my left was pegboard with roughly 30 assorted length pegs jutting out at various heights that would have ended me had I impacted there.
 
I absolutely respect coils when I get anywhere around them nowadays.

Have you tried connecting the red wire from the MSD that goes to switched ignition direct to the battery then cranking the engine?

Hey Pinto5,   you know what, i will try the red wire hot to battery and see what happens.  didn't try that yet.  how do you mean "by switched power"  and one other thing that I am not sure if it means anything or not,  on the starter relay there are 2 small bolts for wires, i am only hooked up to the cranking one, nothing on the second (right side) no not talking about the main starter wire. 

Oh i think you mean will it start and run directly on a 100% hot feed?

will look into that also.

thanks  cheers

Good news.... I GOT IT to RUN!!!!     ok i have to go out for dinner before I get SHOT.... she is huffing and puffing for me to get my butt in the truck to go for dinner....

will update later tonight.

thanks all.

Hey Pinto5,  here is how it went down. LOL

When you said to hook the red wire direct to the battery something clicked in my head.  I did just that and yeppers... she fired and stayed running.  The whole situation then came down to having the wrong power source.  Your one little piece was the missing equation that I was missing.  I was going under the thought process that if the red wire was connected to a 100% live source the MSD would want to run/fire up.  I never made the connection that it wouldn't fire till the starter relay directed power to the line, hence keeping the line charged and running.  I was a bit mistaken for then I used the same wire (white with blue dashes) coming out the firewall and this is the same wire that triggers the toggle switch for the fuel pump line. Kinda hard to explain how I was thinking and how I had it backwards.

thanks again!!!

cheers

yes it kills the Msd  and the fuel pump all in one swoop.  do you run a MSD system in your machine?

good deal.  was just curious for you hit the prob on the head.  I spent hours last night reading all the troubleshootin g section on the MSD website trying to figure this one out.  I even downloaded a 192 page PDF and looked through all of it too...  LOL

I was bound and determinded to get it running this weekend.  Funny how one simple mind fart can turn something so upside down.

the car just needs a fine tuning of the timing and needs to get the vacuum lines sorted out plus Angie needs to set up the carb.

cheers

I have a couple MSD coils to choose from when I finally get it installed so I should be set hopefully. Thanks for the heads up.
