" [QUOTE=SteveAZ;549373]There are a couple problems with this methodology.
1. The pump is PWM controlled, by putting it on a relay and running it at 100% duty cycle, you will definitely over run the regulator at idle...probably even more so than you potentially already are. Been there...done that as an experiment...it didn't go well
2. You now have to rewire everything...the DME no longer has control and is pissed
As for it being a bad pump...maybe...send him a new one and let him try it out
