I couldn't stand it anymore, so I went over to the garage to test it. Hit the reset, then turned the key and the pump started. Hooray! Engine turned over a few times and caught and ran for a few seconds but couldn't rev it past 1500rpm, then stumbled and died. Totally silent - no pump. Hit reset again - no pump. Sooo, something is going on with pump or pump circuit. IIRC, the pump should run at all times so I guess it's time to start checking voltage through the circuit to make sure the pump is even getting power consistently. If it is, then it must be internal to the pump itself. Even if the lines are clogged the pump should be whirring.
Now I remember my Caterham ownership. Lots of stuff to diagnose at first, then was pretty solid. Hope this phase doesn't last too long!
