Heres my predicament... I'm not at home right now, but when i was i couldnt get my car started. I inserted a spark plug into a wire and had my dear old mom crank it. I tried lots of stuff, but didnt get any spark but once, and only once. Here is what I checked:
-There is power to the distributor
-the coil has .8 ohms of resistance from neg. to bat. terminals
-new dist., cept for coil...
-i recently hooked it up to full instead of ported vacuum
-new wires (msd, but ive had it running since i put the wires and dist. in)
-some black carbon crap on the metal points in the cap, where the rotor might contact it. i cleaned these off though. not carbon tracks.
well, this is all the info i know about it so you guys know as much as me now. i still have the module from my old dist., should i try that first? I'm not really in a hurry, i am going home this weekend and i just want to be prepared to fix this. How do i test the module? is there anything else that needs to be tested? well, if you have any tips, lemme have em! thanks guys1

Modules?? Changed it to a GM factory style HEI? No spark on a GM HEI usually turns out to be the module. The Haynes Chevelle book has a detailed HEI checkout procedure towards the back. BTW, most aftermarket modules are junk. Stick with GM replacements.

Well, the module in there is the one that came with the (autozone) distributor. I will try putting the old one in and see how it goes first off. It has that big honkin gm logo on it.. gotta love it.

Dang... Okay, i put the other module in and no go. Tested the other module and coil and they are both ok. What else could it be? I know my wires are ok. Spark plugs are ok. Just to make sure, i ran a new wire to the hei, which terminal should it be connected to in the fuse block? I hate it when my car doesnt start...

The added HEI wire goes to a switched IGN terminal on the fuseblock. One that has 12 volts when the key is on. You can also run it straight to the battery (fused) as a test. Gives it a sure 12 volts but won't turn off unless you remove the cable.

The distributor is new. Not sure I would suspect the pick-up coil but just tossing that out.

The hi-voltage coil is seated firmly against the carbon piece in the center of the cap.

Hi-volt coil ground strap was installed

Engine block has a good ground.
Runnng out of things to check on this side of the screen.
