Car died in traffic.., And it started right back up after havin it towed home.. **FIXED-ECU Options

[kevin311]

Thought I had this issue fixed after I replaced the igniter and dizzy last year to fix a code 12. Apparently not. This has happened twice now. Once before replacement parts, and this is the first time since new parts were installed. Left work yesterday and only got about 5 miles and the car sputtered a little and then just knocked off while I was sitting at a stop light. Had it towed home 35 miles and was able to crank it back up and drive it off the rollback.. Temp never got hot, has been staying just under midpoint of temp gauge (is that normal op temp btw?) CEL didn't come on this time either like it had before. It's a '94 GT 5sp. Not sure where to start. I've read it could be coolant temp sensor giving false reading to PCM and killing the engine bc of high engine temp. Does the 5s really have this fail safe?! Thought it was odd. Also read it could be clogged cat converter, but not throwing any codes. Considering I've replaced just about all the ignition components since owning the car I believe it may be fuel related. Any input is appreciated. Thanks in advance guys.

With this your problem is most likely Not in the wires but in the connection between the male plug on the dizzy and the female connector plug.
What you would want to do is use your ohm meter from the ECU plug and see if you can read the pickup coils on the dizzy from there. Unplug the battery too.
So you want to figure out which wire/pin on the ECU is connected to G-,G+. and then between Ne-,Ne+
And you need some tiny needle probes on your millimeter, or clamps to hook to thermostat (18ga) wire or some sewing needles.

I've got More details on how I did it in the thr3ad I linked at first, ill dig for them after Diff EQ (around 2:00)
