[QUOTE="Catmonkey, post: 16272645, member: 124025"] I'd probably use a jumper and see if you can see it running or hear the pump motor. It's easier to see turbulence in the reservoir with the engine off. That would be one way of doing it, but wouldn't tell you if it's an intermittant problem, or just a bad relay. If you have an infrared heat thermometer, you could see what the coolant in the heat exchanger and the reservoir are doing by periodically checking. Just realize on a cold engine, your pump may not energize until the intake reaches the set point for IAT2. I shouldn't take long. If your heat exchanger is always ambient, you might have a pump issue. If you have a later programmer, you could monitor IAT2 with your flash tool. If you see temps exceeding 130 degrees when you go WOT, you probably have issues with the pump. Best method would be to see what IAT2 is doing. If the pump isn't working, your IAT2s will just continue to get warmer as you drive because coolant is staying in the intercooler. You could also do a data log with a lap top and monitor IAT2, coolant temps, timing and rpm. [/QUOTE]
