No power from distributor to spark plugs...

I bougth the distributor 7 years ago, but since the hot rod building took more time than expected (surprise, I guess..) It hasn't been any test start attempt before now.

-12 volt power in to the distributor is checked. Both with the ignition key "on" and also with the starter engine engaging.
-The spark plug wires are changed once, so I presume those are ok.
-The spark plugs are brand new.
The distributor is a Flame Thrower D1000 (vacuum advance, coil in cap)

Suggestions? I'm a newbee, so don't rule out the stupid and obvious things...

Are you using some kind of spark tester to determine if there is spark? If not, get one they are cheap. Use the in-line spark gap type as opposed to neon.
Also open the distributor and see if everything is in place.
Make sure the rotor turns when cranking the starter.
A new distributor could be bad, not likely but it happens.
Possibly call Petronics.

Do you have both power, (12v) and a good ground going to the distributor? An HEI style needs both.

I have wired the distributor with the two wires according to the instructions:
-Wire from battery power.
-Wire for tachometer.

There are 3 more wires going from the cap and down to the module. But these are wired from the factory.



The motor is grounded to both the frame and the body.

I don't know that dizzy, but you need a ground for the coil. Pull the cap off an read the lettering on the cap. I'm sure that's the prob.

The coil has a ground wire that connects the coil to the distributor body. Then the ground path is through the distributor body to the clamp and clamp bolt to the block, etc.

Has the spark tester been tried on a known good engine? Tried it w/the tach disconnected?

Have now tested without the tach wire. No difference.

Do you mean the centre carbon pick-up inside the cap? Everyting look to be ok with it.
The spring contact on the rotor shows a small mark after contact with the carbon pick up, like I suppose it should.

As for grounding: 3 wires are connecting the cap with the coil and the rest of the assembly. This is like it was from the factory. I have not done anything to these. One of them are black and it is marked "ground".
Here are some more photos. If you see anything wrong, please let me know!

If the hard links from the coil to the terminals are not broken, you have 12v to the terminal but no spark......one of two things.....bad ing module or bad coil...... my bet is on the module as mine has crapped out twice before.

Test the coil. If the coil is OK, move on to the pick up coil. Test it. Photos and text on this HERE.

Then if the coil and pick up coil is OK, I would assume the module to be defective. Many parts stores will check the module for free.
