It was a good drive until the tow truck had to come

I think it's ignition related. I haven't had a chance to look at it yet. Need to have a some water, a beer, and food.


The tow before me threw a rod and obviously the driver didn't care to wash the oil off, so I get the pleasure of oil coated tires.


The car started right back up when I got home.

Probably yellow relay or CDI box flaking out based on your symptoms. Good luck.

I'm sure you checked the obvious. We will see what it was so then we know what else to beware of.

Don't you just hate it when that happens.....only to spend the $$$ for a tow and the damn thing fires up when you get home? Don't forget to digest all the wisdom on our sticky relating to this topic:
Sticky for common answers to why "My car doesn't start...."

As to your primitive needs post-trauma, you need to set your priorities straight. Beer first, then maybe food if it's readily available, but beer has enough carbohydrates to qualify as food. And water....well, what is the major ingredient of beer? Seems a six pack would have you covered.

Don't they have AAA in TX? Pays for itself on the first tow. But you gotta be a whiney baby on the phone to get them to send you a flat bed tow.

I actually used by insurance road side service which was no out of pocket because I had the "plus" level. It's pretty clear they don't discriminate on tow companies other than they must have a flat bed. They call it a "soft tow", but that soft tow tweaked my fog light and possibly my valance. I'll.

I did check the boost relay with another relay. I think it's the CDI and or coil. I have both fuel pumps, so I don't think it's the relay. It cut out very suddenly. I was taking off from a light and it stumbled and then stalled. I got over as quick as I could. I swear I thought the lady in the generic Japanese car behind me was going to hit me (currently no rear bumper on the car).

I think the coil is getting hot and failing. I need to check the resistance between the terminals. In any event I think I'm going to switch over to and MSD set up (MSD 6al digital and high vibration coil). I think I am going to need a tach adapter too.

I felt much better after slamming the water and enjoying the beer.

Ive been there, actually humbly still go there from time to time... Ive had issues with my car mysteriously unstarting and unpowering over the years. Actually was acting up last night, ran fine, almost home and everytime I hit a bump the car powered down and stuttered for just a second and let out a huge backfire from the zork, all the way down the street I live on for a mile... Just installed the AFR gauge and the 20 pin connector in the back historically works out a little, took a wiggle and reset and all now good. Also had a cracked battery terminal which on occasion would totally unpower the car, I'd got the flatbed home and it fired right up but didnt fire the next morning... Good luck finding the gremlin.

mine was doing that a while back the green wire from the distributor was shot. The end that connects to the dist was cooked and the connecter burnt and brittle.

That was one of the first items I looked at. I haven't had a chance to look at it yet, but that is on the list. Good suggestion. On visual inspection it looks new.

mine looked new except the last few inches next to the distributer was brown and cooked. Radiant heat from the turbo

I'm going to order an msd system, does anyone know if the 78 tachs need a tach adaptor? From what I searched it looked like it should be close and should work, but to be 100% accurate it needs to be calibrated?

John

John,

I purchased an MSD 6A-L system (i think im saying that right) for my 930 but never installed and ended up selling the car. If you want I would sell to get it out of my garage and save you some money.

I just went out and checked. It is the 6AL and has the tach adapter along with the coil... he even included all the hardware. The PO installed it on his car and then ended up going with EFI at the last minute so no need for it. Make me an offer or feel free to ask what it is worth. I think I paid around $300 but have no idea what they go for now. It has been in the box it was shipped to me in for 2 years.

Regards.
Bryan

Installed a MSD 6AL in my previous 78 930.
Did not need any tach adaptor

Thanks Totle. I was hoping for that.

x98boardwell, pm me what you want for the box and coil shipped to 78613. Thanks, John

Sun Devil (or is it John?),

So, your quest for information has morphed into recommendations for MSD ignition. But, have you found the culprit yet to your sudden stoppage? Could be ignition related as you suspect, but could just as easily be fuel related. All the gizzmos that are designed to protect you in over boost situations (the yellow relay, the overboost sensor switch, and that mysterious silver box beneath the drivers seat) all work in devilish concert to mess with your brain as well as your ride....and they cause sudden fuel pump shutdown that can feel just the same as sudden loss of ignition.
MSD is good chit Maynard, don't get me wrong. I just hope it solves your problem.

There's a good diagnostics guide halfway down this page from Permatune.
Perma Tune High Performance Ignition Systems
It includes 2 relays specific to 930's.
I prefer MSD but this may help.

Mark,
I haven't had a chance to test any of the components. This darn thing called work and travel have been getting in the way. It's going to have to wait until after the holiday. I'm going to check resistance across the terminals and go from there. I did swap out the relay and that's not it. I did that while I was on the side of the road.
Jfairman,
Thx for the link I'll look it over while in my travels.

An update. While I was on a family vacation my wonderful buddies came over and diagnosed the coil as the problem when it gets hot. The coil, when hot goes well out of spec. So, I'm going to install a Crane Hi-6N and coil that should resolve the problem and give a very good spark. I'm looking forward to getting back on the road.

John

I got the Crane ignition in (Hi-6N) along with the different coil and weatherpak wiring. It starts and runs. I'm happy about that. I haven't had a chance to take it out. It's too late for the neighbors. Maybe tomorrow. Unfortunately, I may now have a rear fuel pump out. I hope it's just electrical when I was in messing around with the panel.
