Thanks.

That hole is blank so you can take the sensor out to test.
Good luck

What’s this sensor?

The picture doesn't look anywhere like my 95 3.9. It looks like it is in the fuel rail so must be the fuel temp sensor.

For future reference - it was the fuel temp sensor. Sounds sweet and fires up at all temps now. Idling a little high but that’s the next problem.

I was wrong - she tricked me. So, hard start when engine is hot is back. New symptom - when using AC and keeping the interior cool, it fires right up. Once the cabin gets warm again, hard start. Coincidence? Thoughts?
