76 2.0 d-jet. stock displacement, hydraulics, with smog removed and backdated exhaust to 74 2.0 SSI's with Triad.
Runs great. Pulls hard to redline in 4th with no missing. Idles 850-950 when warm. Starts up when cold just great and idles 700-800. After running 10-15 minutes to town and going in the store for 10-15 minutes, come back out and turns over but doesn't want to fire. Pedal to the floor and turn over for 30-40 seconds and it gets faster and faster and finally fires up. Then runs great. If it sets for an hour or more , no problem in firing right up. Searched here and the only thing I can see that may be causing this is the distributor plate spring(s)? The wiring is all fairly new, so I don't think that would be the problem. Checked all of the connections and they are clean and tight. If the dist plate is sticking in the full advance would that give me these symptoms and how would I fix that? Grease? Special type? Thanks for any help, Tom |

Since it happens warm, have you tried to check the resistance of the temp sensor? I believe it is supposed to be 20000 ohms when cold and under 300 ohms at operating temp. If the temp sensor is ok and the FI is working as designed then the engine is not getting a rich fuel mix on startup as it does when it is cold. Have you checked your vacuum lines? A vacuum leak could leave you with a too lean mixture. Of course, it should also leave you with a high idle which you are NOT getting.
Do you have a vacuum gauge? You wrote that you do not get black smoke when it does start, maybe it is too lean. You also wrote "I've pulled the plugs after cranking and not firing and they are not soaked. " Are the plugs at least a little wet?
