Aaron,

I had the same issue with 1980 when I bought it. It would always start, but periodically die. It sometimes would start within minutes. Other times, after several hours I would have it towed home. The it would start.
Turned out to be a short in the distributor. I bought a new one and have had no issues in three years.


I still contend that the issue with Aaron's car is something like this, and NOT the DITC.


I had that issue on a VW fox... Was frustrating for months and I even bought a second car because of it. After a shop swapped in a test distributor, and I bought another one, no problem ever again and my then GF drove it for years.

Check to make sure the wire to the over boost switch is not shorting to ground and that the switch is open.

Thanks everyone.

Though the problem was not 100% confirmed (and it now seems the dizzy may have been another good thing to test) I went the way of converting the ignition system to a 'MSD 6530 Programmable' as seen on this board.

I decided to go this route because through this I am just now learning how to test the electrical system -I've never done anything like this before (I didn't even know how to check ohms when this began). And though I've received a lot of help offsite from, Dan, Vaughan, Hank, a number of individuals via FB, I can't help but 2nd guess my own findings -or lack of them! The MSD conversion began looking like the best solution (at least for now) as I can't help but question the Crank (Flywheel) Sensor as the possible culprit.

I apologize for not properly updating this thread. Until I found myself pushed into seeing this car through, it had been on the back burner so very long that new habits had left me forgetting to check in while help was being provided. I truly am sorry about this, and wish to again become a more active part of this community -as I once was. Beyond that, I've also rediscovered my passion for these cars and have come to a place where I don't feel it's right to deny myself of it any longer. We all need to have that something we enjoy -right?

Congratulations !!
You are one of the VERY few that when they run into trouble with their 924 they get down to it and solve the problem instead of parting the car or selling it for peanuts...or just abandoning it.

Well done! Any tips or tricks to add regarding the install?

Thanks guys, I’ll never give up on her –she’s been with me a long time and she’s not going anywhere!!!

ABSOLUTELY!!! Once completed, I’d be more than happy to offer any assistance I can to others who wish (or need) to take on this conversion.

I wouldn’t have been brave enough to jump in this as I have if it wasn’t for the info provided here on the board, as well as those who’ve been willing to guild me. In fact, in the beginning, (though the how to here accompanied with the MSD wiring diagram is pretty easy to follow) there’s still lots to be confused about –at least for me there was. I actually still have a few things to sort, but I should be through them very soon (as mentioned, I’m awaiting my final order).

The most intimidating part of all of this is; you CANNOT call MSD, Crane, or anyone and get any noteworthy information –unless you wish to take notes on feelings of discouragement. This is basically considered impossible –because there is no plug and play solution designed for this car, and MSD will tell you their box WILL NOT work with this type of fuel system, nor with the dizzy. For myself, being someone who needs to be VERY concerned about spending, this aspect of it was extremely scary -but I’m beginning to feel a bit more confident. If you’ve not checked the box out yet, I suggest a YouTube search. It’s actually very cool!!! I almost look forward to the upgrade as much as having, Elita back.

I’ll be sure to check in regularly, and keep you guys updated on the progress.

Still at it guys.
The plugs are receiving no spark.
However if I manually trigger the MSD, the coil puts out a bolt of lightning. The problem is within the dizzy (lockout, pick-up, something). But proper installation of the MSD has been confirmed. I'm almost there. Once I have a running car I intend to relocate the MSD unit, at which point I'll write up something very detailed and easy to follow (from A-Z) -with photos, and I'm now thinking it may be best if I include test procedures (all the things I'm learning).

Just wanted to offer an update -I've not forgotten.

Figured out where my issue was. Now it's running, I'm getting close.

Glad you got her running again, man! So.. where was your issue? You've got me curious!

Thanks, Dan. For pulling me back in and keeping me honest with your request.

First, I apologize to everyone here for my not updating as planned. Believe it or not, I do wish to be an active member of the board, (and I’ve been online. I have no excuses), its just life. Life can certainly drain you –in all sorts of ways –and pill of failure swallows like a jagged rock.

Via FB, and fellow Porsche owners from here (and not) I had much online help in solving Elita’s riddle. In fact too much to still have failed in the end –or at least this is how I’ve felt in returning with an update. I had high hopes of taking the information provided here and tweaking it into such an easy step by step that even someone at my level would not fear the taking the step. But reality is, I’ve not been able to conclude with correct timing. In fact, my timing may be further off than I had realized and caused further problems.

HOWEVER, I turn that key and not only does she start and sound smooth, but I would also have no doubts in her ability to go all day and night (she does NOT shut down as before). The funny thing, even as incorrect as she apparently is (or was during the process) I’d have more confidence in depending on her now than ever before.

Back in the day, I replaced the clutch, everything associated, going as far as even having the Flywheel shaved. But new to it all I made a costly mistake; I failed to mark the Flywheel before removal. Listening to local mechanics I reinstalled only to have it ‘unknowingly’ fire on the exhaust stroke. Those who believe these cars cannot run at 180 off, I will argue are incorrect. Though it fluttered slightly, it didn’t run too bad. However coming into boost resulted in not one thing good –and no power to boot. Thanks to the help of those here I discovered my error and made the necessary correction. Unfortunately in the process of it all I developed head issues. I thought I had destroyed my head, come to find out much later I only toasted the gasket.

That is why its been so important to me to have this completed correctly before even beginning to simplify and expand on the ‘how to’ conversion that was so thoughtfully provided by another member here. Much of the part that confused and intimidated me lied within those numbers and their explanation. I believe this is where I failed, and feel very reluctant to address the ‘how to’ as I had planned –not until corrected and verified (A financial undertaking beyond my current means). I believe I executed another head gasket through improper timing.

I know this may sound unrealistic, but I am not knowledgeable enough on this to say for sure. What I can safely claim is, I had no headgasket issue before incorrectly installed flywheel, NOR did I have a headgasket issue prior to this conversion. Believed related or not, to me, this appears probable. However there’s a big difference between than and now. I had a mixing of fluids with my last headgasket issue. This time, all I am experiencing is a slight external ‘seepage’ of oil, that to be quite honest, doesn’t amount to much. The loss is minimal and I’d drive her just the same, IF it were not directly above the filter assembly and dripping straight down on the exhaust –causing much toxic smoke to come up around the car and occasionally in from under the shift boot.
Adding to my shame, being without a car for so long greatly changed the road my life was on, I’ve not yet recovered the means I had lost, or finished filling in the hole the ex left me in (before digging it deeper to fix my car). The truth is; I cannot afford to bring my head to the shop at this time, let alone afford the new head gasket. This is why I’ve not been back, I cannot yet complete what I purposed, and I’ve felt quite ashamed of this –each part. What respectable Porsche owner, who cares properly for his car, CANNOT afford a damn head gasket!!! The shame felt is bad enough, and then I’ve added insult to said injury by not living up to my word here. To me, my word is the one thing I do have.

Thank you, Dan. This needed to be addressed –my plate feels a little more manageable now.

Aaron
