Really! I fuel temp sensor in the fuel rail! I personally have NEVER seen one! Where is this temp sensor? What does it look like? Is it available only in Canada? Or is the sensor somewhere other than in the fuel rail itself? Does this sensor have wires going to it, or does it send the signal to the PCM via radio waves? I have had litterly HUNDREDS of fuel rails off of the engines and have only seen other than fuel injectors and a fuel pressure regulator on return systems just metal tubing and high pressure "hose" . Maybe the metel tube itself is the temp sensor!
The point I made about the octane is valid! At cranking speeds there just is to much time available to light the fuel off for a 5 octane change in fuel burn rate to make any REAL difference. Like I said at HIGHER rpm's were the TIME to sucessfully light the fuel off is GREATLY dimminshed does the octane rating have a significant impact. Low compression is not the issue here, 9.3:1 is pretty decent for a 87 octane engine!
One other thing, it was NEVER said that this was a HOT START problem, apowers2k said the problem was on first start!
Still looking for the elusive fuel temp sensor!
