Thanks for the thought
With mine, I've tried connecting the pump direct to the throttle diaphragm (so no brake switches to present problems) and with the pump given 12v to the top and bottom terminals, and the central terminal earthed, the pump still can't pull the throttle.
It just seems the throttle springs are too strong for the pump to overcome.
I've got the same problem on two cars having tried 3 cruise control pumps, 2 injection pumps/springs, and two different throttle reels...
Would you be willing to try connecting your pump as above (just with the connector removed and a couple of jumper leads to the pump from the battery) to see if your pump opens the throttle fully when connected up?
Thanks,
Jim
