Chef, could be just a bad or broken coil ignition cable. If the distributor has been out or replaced it maybe 180 out.

Did you do any work on the car prior to this?
Or, was it running and now it isn't.
Could be a lot of things if you just worked on it.
Probably the Pertronix shutter unit if it just stopped.
Look at their site for troubleshooting the unit.

if the pertronix is hooked up backwards it will fail.
did you do some work and forget to reinstall your rotor?

rotor is in, petronix is in correctly ( i think), was trying it with points and had the same result. coil wire is new... this 180 thing sounds interesting, how can i tell?
update... tried a different coil same sh..., went back to original and retested voltage came in @10.3. volts

Put #1 cylinder at tdc. Pull distributor replace distributor so the rotor is pointing just short of being straight towards the left side of the inspection hole - actually more like the bend in the black flapper rod. Make sure the cap has the plug wires in the correct firing order and the rotor is pointing to fire #1.
Retime with strobe light after it starts.

I just went through this with Paul (lotus65's) car. He has points so it was easier for me because i was able to use my static timing light for a starting point.

Even if the distributor is 180 out he should be getting spark when holding the ign wires close to ground.

Speaking of ground, is your tranny ground hooked up?

thanks i,ll try that. by the inspection hole do you mean the round plastic plug used for timing? also i just tried putting a screwdriver in the coil wire a 1/4 inch off the tin and turned the engine, no spark while it was cranking but a single spark when i put the key back into the run position did it 6 times to make sure i,m not nuts

Sounds like Ign switch is miswired or the ign wire is shorted to ground when the started is engaged.

As said above, What work have you done recently??

Rich says he has no spark - not a general no start issue. The 180 thing would not stop the spark. Just it would spark at the wrong time. He has 10v at the coil - that's low but not low enough to stop a spark at all. You are going to have to look at that at some point Rich. There was some thought in another thread about the miswired switch giving 12v only in the on position (not in the start). Measure again while trying to start. If you have 12v to the coil during start then the problem has to be somewhere in the dizzy - no switch to ground.

Edit:
no spark while it was cranking but a single spark when i put the key back into the run position did it 6 times to make sure i,m not nuts

That really sounds like it may be the miswired switch. You get the spark when the key goes back to 'on' and the motor hasn't quite stopped. Maybe?

this is a 74 engine that was running that i put in my car to replace my 1.7. d jet. i put in all new seals and a new clutch. and put it in. i just now tried chappy's idea of bringing the #1 piston to tdc and have discovered that my rear wheels will only move a 1/4 of a turn , then there is a thud, this happens in all gears. i can hear the clutch shifting although it is a little spongy. it doesn't seem to be the brake, the emergency brake holds fine.

First things first. Measure the voltage at the coil with the key in the start position.
