Responses are cretainly appreciated however it appears the discussion has been sidetracked off the original issue.
Let me preface by stating I have 31 years experience in the instrumentation and controls field with a major electrical generating utility so I absolutely know my way around metering devices, electronics, relays (you would not believe the variety), control theory, etc. Trust me - I have probably seen it all at one time or another.
For example you have a $30 oxygen probe for your car. We have stack O2 probes (also zirconium cells but many times more complex)) that cost over $8000 per probe and $150,000 for the complete measuring system. You need this to accurately measure down to the .01 percent accuracy required for efficient operation of the large boilers.
Secondly my question was merely how is power to the pumps routed when in the "starting" phase. I see only one route - through the normally open contacts on the drive relay. So far the only way I see to seemingly "bypass" the drive relay function is to indeed have both "start" and "engine running" inputs land on the same relay terminal (one side of relay coil) so that either will energize the relay coil, and close the NO contacts. Yes this would require some sort of diode setup.
With all due respect, I don't see how your theory of bypassing the relay and energizing pumps is possible any other way short of an additional relay.
Please do not take this as any form of disrespect. I am learning more about this car everyday and the info I get in these forums is indeed invaluable.
