Was this car running before... or is this a new build.. do you have both the run and crank wires jumped together out of the ignition switch so it has power during cranking and run

Have you tried to start it by jumpering the starter relay? Thats a good way to test the ignition switch to see if both wires are connected together.. since its in the run position

Switch is good, 12v incomming is good, 12v(thick) red is good. It acts like im not signaling thru the distributor pick up. With the test you did(jumping the box side of the dist) thats what the test says also... I just went through this last week.. but when I jumped the box side it had a spark at the coil lead just 1 time then nothing.. my coil was shot... after changing the coil.. it runs better than it ever has

I went through the troubleshooting guide that came with it and also their website. I ohmed out the distributor and got .287 on the 2k scale.

Hmmm. Seems like you checked everything. Box is probably done.

Had a brand new MSD box that didn't even make it out of the gate.

Only when I jumper the violet and green wires from the box side. So The coil fires when you jump the violet & green wire. That proves your wiring & box are good. Next step is to verify the distributor will trigger the box. Set-up the same test but leave the distributor violet & green wires connected. Pull the dist cap & rotor. Loosen the distributor hold-down so that you can turn the housing. Then rotate the housing so that the pick-up coil moves across one of the teeth on the trigger wheel. The MSD should fire the coil every time the pick-up moves across the trigger wheel. If you position the dis pick-up & trigger wheel properly, you might be able to use the distributor advance to move the trigger back & forth across the pick-up. Coil should fire every time you do this.

Sounds like the pick up coil in the distributor was bad. I ran my car for years with an OE distributor and a digital 6 box.

But that distributor worked excellent in my other car. As its back in there and running. Dont know what to tell you.. I never ran a digital 6 but have run plenty of stock dist with 6al and 7al boxes.. both lean burn and dist with timing... so I would think that the digital box doesnt like something about that dist.. might be the difference in the resistance
