Doc here,

Thanks!

Hope it helps..you or anyone else maybe looking for specifics..

I have to remember that there are a few guys here that have never worked on a points type System, at all by virtue of how much HEI has become a presents in the market..and how really different the systems are..(physically)

And then there are a few that come here, and never have worked on either..and get confused when you ask HEI or points type..

As you and I know, they are totally different in approach (although they do the same job) So I thought I'd put it out here, for those that have done neither or needed the procedure for HEI..something they could pull up from the knowledge-base and work with..

And then there are a lot of guys that know how to do it but lack the Ohmic values..so I thought I'd Add those too..

Hope it helps in future!

Doc

Hey Doc.Thanks for all of your help.It has been very informative.I dont understand what you mean by module?Where is it located on the car and what does it look like?Also,I replaced the coil today.My distributor is HEI which was put into the car before I bought it.I had to buy an ignition coil from a 78 Camaro and it matched perfect to the one that was in there.Anyway,I replaced the coil and the car still didnt start .So the next step would be the module if you could explain where it is and what it looks like(sorry still kinda new to cars.I am only 19 but I am trying to learn)Thanks alot!

Module

Doc here,

Here is an exploded Version of your HEI:



See the Brake pad looking thing in the upper center Marked ECM? That's your module, Sits on the advance plate inside the Dizzy..Can't miss it..

You ARE sure you are getting a WEAK spark, right? And not none at all?

Cuz if you got NONE at all it could also be The Mag pickup..But USUALLY (rarely) not if you had Some spark..The mag pickup and pole piece are on the right side of the photo..

Sorry about the crummy pix, you can download it and blow it up, and print it out to make it more legible..

Doc

Yes I am getting a spark.Its like an orange color and the other guy I talked to said that if it was orange then that means it is weak.

Also,about 2 weeks ago when the problem first occured it would only start after I cranked the motor 3 or 4 times and let the car sit.I would crank it 3 different times and the car wouldnt start.I would let it sit for about 10 mins and try again and it would start but only stay running for about 10-15 mins and then just die out.Was it starting like that because the module was heating up from me cranking it over?Now,I cant even get it started.It got worse as the days went on and now it wont start at all no matter how many times I crank it and let it sit.

Module

Doc here,

Classic overheated Module Failure..

runs cold until warm then dies, until cold again, until finally won't run at all..

Get a test on that module. or just get a new one..

Doc

ok, future reference. lol... you need to tell us everything that was going wrong with the car prior to it dying. i'm not trying to come off as a d***. but if we knew beforehand what all was going on you wouldnt have wasted money on another coil. but yeah. Doc's right, its the ignition module.
