Ken you likely have a bad thermopile have you checked or replaced that on the unit? That is the device with the wires to it and the most likely cause of the problem. You can check it with a volt meter for 350+millivolts at the valve where the RED and WHITE wire connect to the valve.

No the thermopile is completely different that the thermocouple. The thermopile is the large sensor by the pilot.
Ok I will be out for just a bit but will post back. The only two things that typically cause that issue is a bad thermopile or bad valve not much else.
