The car has no fire at the coil. No power at distributor connection cranking off or on. There is power at the positive coil terminal. There is power at the ballast. The ballast, ignition module, coil have all been replaced. The electronic distributor has been removed and replaced with a Pertronix distributor wired directly to the coil. All wiring has been testing for continuity, there is no apparent problem, the car will not start it has no fire. It will not start in crank or on position. The car started and ran, started at least 10 times and ran for about an hour (for 20 minutes while breaking in the cam at 2,000 RPM.) The car was turned off and the temporary Holley carb. Was replaced with the original thermo quad which is pumping fuel. The car never started again. Help please anyone. Thank you.

If there is power at the coil and there is fuel then it's either out of time or no compression. You said the cam has been replaced as well. If the ballast has power does it have power on both sides? And if the pertronix is good and the coil I s getting power it's got to be a rotor or distributor cap. One of those is grounding out. Not allowing the spark to go to the wires.
