Check out the pictures I posted. They show the plug and it's approximate location. Sometimes the plug will get pushed down behind the wiring that runs in that area. On some cars, it may still be shoved up into the dust cover that is attached to the fender well in that area.

I was just having a similar issue. My PIP sensor inside the distributor went bad, it will do the exact same thing as the TFI (no start when hot). It will also burn up your new TFI. Since you are already balls deep into this issue, I would replace the distrib with a reman unit from the parts store... only about 100 bucks.

jrichker stated it a few times for you to pull codes and gave you pictures to where it is located in post #7, now as mentioned before pull for any codes. The car is not OBDII that is located undder the dash, but that of the prior OBDI which is located in the engine bay. There is a plug on the driverside near the hood hinge between the wheel well and firewall that you need to plug into with a OBDI plug scanner or a jumper wire. The scanner is cheap from AutoZone for like 15 bucks, it has a small light on it that will blink at you in series. The book that comes with the scanner will explain what series of readouts are for each code. It will usually blink one session and then another session to make up a actual code. Easy enough for anyone to use. But trying to diagnose something with limited info online is like throwing darts at you, and all it does is empty your wallet. So my suggestion like many other before me are telling you is to read the codes.

Here is a code scanner for your car at AutoZone:

Please start you own thread and don't snag an old thread from someone else. That way it will get the attention that it deserves and not be overlooked..

Answer is still the same. Run your check engine codes. Not all OBD1 codes cause the light to come on. Pulling the codes first gives a much educated starting point rather than random guessing

Oh shoot man you were serious. I just figured with your post count you were busting balls over it being reader and not a scanner.

1991, doesn't idle well. Once the engine warms up it won't restart. It emits black smoke so I think it's rich. The fuel pressure regulator has been replaced, and the IAC, TPS, distributor and injectors have all been replaced.

I no the foxes have the control module on the distributor so I'm not sure if the distributor floor the fox has the pickup coil inside like a 9495 do. The pickup inside also the stator when they go bad it'll cause an issue to wear you can be driving down the road after the car is warm and it'll shut off and it will not restart until it is cool to back off.

My mind used to do that years ago which over a 20-year period I only replaced it twice and every time when it did that, after about 10-15 minutes when it started back up I could drive all the way home say about 50 miles so it was crazy how it did that and still allowed me to go all the way home. So that's just one thing I'm thinking about when you say a hard start to win a warms.

Try googling that situation when I was trying to find out what was going on with mine which mine ended up being a tune issue which was mostly only during the summer time not even the winter when the car is warm, but during my search I found a lot of topics on hot start issues.
