Several times , months apart, when the car has set several weeks, the car fails to start. Engine turns over fine. I have 12 volts to the distributor with key on. Put spark tester on plug wire and no spark when cranking engine.  Each time this happened I have done the same procedure. Disconnect Tach and battery wire and wire connector from distributor. Pull coil out and clean contact and rotor bushing. I stretch the spring a little on the rotor bushing to ensure good contact. The rubber bushing sits on top of the rotor bushing so it is installed properly. Ensure the grounding strap is secured. Put it all back together and it has fired up on first crank each time. I know there is two different rotor bushings that comes with a tune up kit but I don't remember which one I used. Distributor cap and components was put in last fall. It's an Accel kit. I'm leaning towards the rotor bushing spring is the problem. Any suggestion on a high quality cap and coil components that's worked for you or what else may be the problem?

Go to yer local dealer, or parts house, and get an AC/Delco cap, and a new rotor. No reason to buy Accell crap. Thumbs Up

Agreed...GM/AC DELCO is better than the 
aftermarket stuff IMO. 

I forgot to mention…check for  side to side and excessive up and down free play in the distributor shaft.

 After frying my coil out on the road, I went straight to the Ign. module and replaced it. Well that wasn't the problem but it did reveal a lacking of dielectric compound under the module which I replenished. Besides saving the module from future burnouts I'm sure the grounding is much better. It actually seems to start a little faster and run better but that could also be the new coil and module. I'm going through my vettes to insure there's plenty of silicone compound under each module,..you know, peace of mind.

Thanks for replies. Changed over cap and rotor to Delco/Remy, checked distributor (1 year old) for play, and module has good coat of di-electric. Will let you know if problem persist. Thanks again...

You need a new coil pick up in the distributor,that's the one that has the wires going to the modual and "sees" that distributor pulse to fire the engine the wires are bad that connect them together

Can the coil pick-up be intermittent like I'm experiencing?

I agree with Per4mance I would be willing to bet the pick up coil in the distributor has a broken wire I have seen it several time it can be vary frustrating. You replace stuff and it will fixes for a while then all of the sudden no start. Check the plug and the wires going into it

If the PU coil does prove to be the culprit and I have to pull the distributor I think this would be a good time to just replace the Accel distributor. Steer me to a good reliable brand that has worked for club members. Thanks

AC Delco…..I had this same distributor in my old crate motor since 2000. It's still out there running that same engine just in another car now. It never gave me a problem. the only thing I did was put a looser set of advance springs in it. 
You may be able to get it cheaper if you shop around.

Thumbs Up +1 on using GM parts to replace....IF you determine the pole piece is the culprit.
While the pick up coil/pole piece can cause no starts, they usually do NOT work one time, then not the next without actually moving or otherwise disturbing the wires on it. If the wiring is frayed, or the insulation has fallen off, which is common, if the car does start, it usually don't run very well. The pole piece itself is fairly dependable, but the insulation on the wires to/from it sux, and as the advance plate moves back/forth while running, it can cause the wires to touch, which always causes a misfire, or other symptoms, such as a start/stall issue.
Give the new cap/rotor set-up a few days/weeks to see how it works out before condemning the dist totally....unless you just happen to have some spare $$$ laying around ya wanna get rid of. LOL

Thanks for the website on the distributor. That's a fair market price. I'll take Adam's Apple advise also and see how the new components work out before I switch distributors. I'll end up changing out anyway but for " lesson learned" I'll run what I have to see the outcome. I'll be staying local for a few months anyway so I could use the exercise if it strands me. Appreciate the replies..

78 still firing up on start attempts after changing to Delco cap and rotor. Question though. Is it possible to get 12 volts to distributor wire with key in the on position but lose it when moving key to start. If the no start shows up again I'm going to put on a test light to see if I have 12 volts in the start mode also. I can't remember if I've ever changed the starter switch  but the crate engine and every other attached  component is only a year old. Runs great under loads and cruising at 75. Thanks

HEI system should have a full 12v(or battery voltage) on the red wire any time the key is on...even when cranking. A test light will not tell what the voltage is....it will only tell you there is enough voltage there to light the light, which could be a little as 2 volts. You'll need to check that with a multimeter.


Glad it's been firing up otay so far!

Joel, good advice on the voltmeter, thanks. I have a new GM Delco Remy distributor waiting on the work bench just in case the gremlin pops back up. May of already fixed it with the GM cap and rotor I put on a few weeks ago.

The AC Delco distributor I just acquired has two extra wires coming out of the distributor that isn't on my current distributor and I need some confirmation on there placement. One is black with a round terminal on the end that ends up as two black wires going into the terminal connector just behind where the tach and batt wires hook up. I'm assuming that is a ground wire that bolts to the engine . The second is a gray wire that has a male plug on the end.

If their is extra wires it would be a distributer for computer control (ECM) I think

 That was my first thought, but the later ECM type distributors have a second harness with multiple wires in it that connects to the ECM harness. The one in question here apparently only has two single wires "extra". Need to know where each of them originate...
Wonder if the grey wire with the male plug is for the tach filter?
