if it fires it is getting spark, the wiring of the starter would not effect the spark. Just to be clear, from the time the car was test run to installation in your car, the plug wires and the distributor were never removed?
Are you sure its getting gas?
From what you have stated, you are getting spark...have you pulled a plug and cranked the engine to see if it fires?
If you have spark, then you don't have fuel.

thanks for the reply..yes its getting gas so much you can smell it ...its like when i turn the car over and it fires and i release the key it dies ...that is why i think its got something to do with the wiring ..i am not sure if going to the new type starter with only 2 wire contact points from the old chevy starter with 3 on the sollenoid makes a differance

Just reread your OP the small term on the starter should only have a purple wire on it. If the yellow is on at the starter and at the coil the engine will fire but will be killed by the yellow when you release the key.
What is the other wire you say is on this terminal that comes from the fuse box ?

Not familiar with the MSD wiring but if you will post a pic of the diagram I'm sure I could figure it out.
Make sure you dont have the yellow on the coil or starter,remove the tach ground from the neg side of the coil,make sure you have 12 volts on pos side of coil,-try to start
I think the fuse box wire should be on the batt term at the starter
