I recently picked up this 79 280zx from an inpound yard. Most of the car is in good shape, Engine runs strong.
The biggest issue I found was the car dies while driving at random times. Yes the Tach drops dead immediately and sometimes it comes back with in 5 seconds, but mostly not. I can while the car is still moving switch the key back one click and on again and it comes right back, well sometimes it takes a couple of tries to keep it going and then it runs for a while again.
I did search all the posts and tried everything I could find(i.e cleaning all connectors, checking EFI relay, Jiggling key when dies) none of these have worked.
I have not changed the Ignition Module yet, because of cost and can't find any outfits that have the equipment to test it. My journey to the junkyards to find a used one is this weekend, but from what I hear these are the first to go.
What are my range of vehicles to look for that have the E12-80 in them?
Any suggestions on testing?
I did see a post to avoid the new ones from AutoZone for around $130, why would they not work?
You have to "BELIEVE". There ain't no reliable test........That's why all the remans are bad....they got turned in as cores with bad modules, and the rebuilders passed them after sandblasting/painting, because, if they were tested at all, they usually tested good.
I did try the EFI Module first thinking I found the fix. It tested fine and then I did open it up and shimmed the contacts shut while driving home, about 45 minutes into the drive it dropped again. So I believe I eliminated that relay.
Thaksk Blue on that.
I did have a friend dig up a book on the Modules made by Nieoff and crossed referenced them. The only other cars we could find was the Maxima and I believe there wasn't a whole lot of them floating around in 80.
Yeah, I found the module very easy to pull off when I cleaned all the connections.
I will post my findings once the change good or bad.
Unfortunately I do not have an exact solution. It turns out to be one of two things. I did pull the Ignition module off a second time when trying to find a place to test it. At that time I did a second cleaning of the trminals and added some WD-40. The second thing I did from time of problem to time of fix was clean the bullet connections on each end of the resitor thing by the coil, this I saw in one of the post.

I had this same problem when I changed my spark plug wires.
Above the coil, there should be a wire with a resistor of some kind and two bullet connectors.
