I have checked the wiring back to the computer (I read 10K ohms resistance across the wastegate soleniod leads until I pulled the computer). Since the vacuum pump works and the soleniod works and the wastegate actuator works and the wiring is good, than either the computer is not telling the soleniod to operate or I have a blown port on the computer. All other engine operations seem to be normal - no codes.
Am I missing something?
I now have an excuse to install a Holset HX35 - new project!
Thanks for everybody's input.
