Have an EX100-2. Anytime you ask it to do something it will kill the motor. Have replaced both DP Solenoids on top of pump including electrical connectors. Have made sure both computers are blinking and fuse 7 is good. What else could be my problem? Pump was rebuilt last year. All new filters and oil (fuel, oil, hydro). Thanks in advance for any help.
Welcome to HEF Thomas ! First does it kill the engine quick or slowly like an engine power issue? If it is quick then make sure F3, F4, F8 and F9 fuses are good, especially the F4 1 A fuse. If all the fuses are good then check to see if you have battery voltage to the solenoids on top of the pump with the key on. They should have battery voltage all the time with the key on and the controller controls the ground to them when operating. If there is no voltage check the K9 pump control relay (which gets it's voltage through the F3 fuse).
