If so, do the diagnostics associated with the Thermotime Switch. If the TTS has failed the CSV won’t fire. The tests aren’t hard and the TTS is easier to access. The TTS is located on the left side chain cover housing in the far left corner. It has two wires going to it. If the TTS is good then it’s pointing back to CSV and you’ll have to verify CSV is firing when cold and cranking.
Getting to the CSV may require a partial engine drop. You may need just enough clearance to remove the “pope’s hat” and have some room to work.
To remove the electrical connector on the WUR just grab it by the base and pull straight up.

Yes I have the Bentley manual. I saw the instructions on testing both the Thermotime switch and the CSV. I will get my hand back there and double check that the plug is on the CSV first and then run the test on the thermotime switch. Going to be a day or two before I can get to the tests and will report back.
