George,

I must have asked you this before, but why aren't you triggering a 
relay from the + side of the coil?

I have a relay that is triggered from the + side of the coil, and I use 
the output of this relay for everything that needs to be on for both 
running and starting. In fact, I pick up a lead  here for my 
non-resisted lead to the alternator.

I have  a trouble shooting guide for the Holley and the back page is a 
diagram for testing if the "Fast Idle  Solenoid Does Not Operate When 
Engine Is Cold"  As I understand it, this is not your problem, it 
happens only when starting, but ....

They do have a sequence that might help. "Hook up Yellow wire to 
solenoid and remove Brown wire from temperature sensor.  Turn  Ignition 
on". If the solenoid does not energize, the problem is in the ECU, if 
it does, the  problem is in the temperature sensor.
