Thanks for the input Peter.

After the car starts I have disconnected the cold start valve, The 02 sensor is new, I slackened off all the accelerator linkage making sure that the idle switch closes and tested it with a meter for continuity, OVP relay seems okay, I have resoldered all the connections. I have made up a lead to check milliamps at the EHA . I'll post readings and results.

Thank you all for the input

Michael
