Reply to "Car will not fire"

Here's the latest. Any thoughts would be helpful.

At the coil, only measure about 11.5 volts, key in run position - Feeding power directly from the hot side of fuse 13 (window fuse) as original run wire was trashed by previous owner.

Brand new Pertronix and Brand new coil. Wired correctly, grounded.

At ignition switch, incoming voltage at the block termination screw is also only about 11.5 volts (big pink wire feeding switch). Backside of ign. switch terminal also 11.5 volts. Battery is definately 12+ volts (new battery) and at the solenoid, 12+ volts.

Crank car, and voltage at the coil drops to 9 volts or slightly less.

When you let off, the car momentarily tries to fire and you may get one spark out the coil wire when grounded to the motor.

Where should I go next in the quest to find the problem. Should I jumper across the solenoid hot directly to the coil to see if it starts.

Tried key in the run position and jumpered across the solenoid with bump starter. Again, car turns over, not start.

thanks for anyones thoughts.
