Morphh, I checked my IC pump: it was not running all the time. After a cold start, revving in neutral would not turn it on. Revving a little in gear while foot braking would sometimes turn it on. Once on, it stayed on. I installed a switch to make the pump run any time the ignition is on. Problem solved. My drag strip cancelled the test n tune tomorrow again because of cold weather. I will have to wait longer to see how well the 5 degree C mod works works.
