A few things to check, One is that you did not connect the Green output wire to the 5v power source for your MAP sensor, If you do this the controller will not have a power up mode it will just think it is runnning on full.
This or you have something hooked up wrong somewere in the system. The voltage you need to check is at the green wire on the controller, The controllers blue output wire and see what they read. Also make sure the controller has a good ground as well as the pump,.
