March 11, 20223 yr Author comment_637102 @siteunseen guys problem solved. I tracked the green wires for the thermotime connector and it was hooked in the temp sensor!!! Car started beautifully. Appreciate all the responses.

March 11, 20223 yr Author comment_637105 One final thing on this topic: my idle RPM in D mode are around 900 and in P (parking) they are a bit higher about 1200. Is P mode idle OK or high? Manual says to check idle in D mode and it is within range. We did change the thermal coupler on the fan as well. Temp was climbing at idle a bit but now it is stable a little below 1/2.

March 11, 20223 yr Author comment_637110 I am able to drop the RPM in P to 1K with closing the idle screw. System looks really good at the moment. Plan to continue driving on HW for the next week or so. I think i need new suspension now (creating new post)!!!
