just yesturday i was driving and i realized my coolant temperature needle never moved from below the cold mark. ever since i put the h22 in the needle never made it to half and it stayed close to the cold mark but now i have no readings i played with the key so see if the needle was stuck but no results any ideas?

 

make sure your coolant temperature sensor is pluged in. And when you did the h22 swap did you put your front thermostat housing on the h22. Cause i have a 4th gen and the usdm f22/h23/h22 all have sensors on the front coolant neck but the jdm motors do not.
