when my RC did that, it ended up being a bad fusible link. i bypassed it with a switch under the dash.

Go to yer wirin' diagrams, ya swabbies! Ya cen see that therrrs a diff circuit be supplying the coil in run 'n start. Iffn you ain't got spark in start, that circuit be caddywumpus...
So Rod, you with Pacnorthcuda that it's the circuit to the coil? I don't speak Pirate-ese.
Do you agree with my test to check when cranking at the coil?

I would start earlier in the circuit. Hook up a test light to the drivers side of the ballast resister, position it so you can see it through the windshield. Crank. Light? if Yes, check the other terminal on the same side (I am assuming at this point you have a 4 prong resister), crank Light? No? Thats a Problem!!! Then do the same thing on the interior side of the bulkhead connector (trace the dead wire--its green I think) does it light? Yes? clean/repair the bulkhead male/female spade connections. No? damn!!! Might me an ignition switch problem.

Yes, if there is no voltage at the coil during cranking it will not start. New engine harness ?

Had a simular problem last year on my 5th Avenue w/318. May sound strange, but it turned out to be the distributor. The bushings where loose, causing the air gap to be almost closed at times, open enough to start others. I run an HEI, so no ballast or ECU. Worth a try.

so what voltage do you see at the coil when you are actually cranking it over?
Sounds like you either have a large voltage drop, or the battery is basically discharged.

8.5 volts at coil when cranking.

Thoughts?
it "runs" so the pickup/coil/ecu (hard components) are good and the ECU is grounded. Check the wiring schematics how it's wired as only the coil positive primary terminal and the "point" of the ECU pentastar connector (4 pin) need fire in start (ign2) as the pickup triggers the ECU which opens the coil pri makeing the secondary fire. Either one of those hard components is not getting fire in "start" or in "start" it is mis wired and something is getting grounded that should not be grounding.
I replaced the ECU and the coil , and checked I was getting a good ground at the ECU when I changed it.
But I understand what you are saying, something is not getting fire in the start. I don't think it's miswired because it was working fine before.
