[First: With a good OVP a warm car set properly will notice no difference when the OVP is unplugged!!!!! can we say "limp home" While warm starting will not be affected.]

So, in MY case OVP is not telling cold start mechanics to operate and may be screwing up the warm operation mode too?

Oops! That's not a valid question. I should ask is it possible and/or likely for the OVP to cause the controls to behave ths way?
