Cranks but no start

[47COE]

Some basic questions:

With the distributor in the block, does the rotor turn when you crank the engine?

Have you set the gap correctly?

With the distributor out of the engine, use an ohm meter to measure resistance between the terminal where the wire from the coil connects and the metal case of the distributor.

Then turn the rotor by hand until the cam follower is on a flat of the cam. The ohm meter should read very close to 0 ohms.

Then turn the rotor by hand until the cam follower is on a high point of the cam. The ohm meter should now read infinity (open circuit).

I once had a distributor that had an internal partial short such that the last test read about 1000 ohms rather than infinity. That was a definite no start.
