ECU Issue
 

Hello.

Does anyone had seen this issue before. I have setup the Xicoy ECU AU-605 Auto Start. Everything was connected and programmed
as the online manual says. Upon power on to the ECU, the pump would just start to run at full speed and won't stop.
Any help would be much appreciated. Thank you all.

Battery and fuel pump or starter connections reversed will cause that.

are you sure your pump is not plugged to the battery connectors on the wiring harness???

Hello.

I had follow the harness layout label on the ECU very carefully. The ECU seems to function correctly on everything else.
Just the fuel pump start to run as soon as power is turn on. I have no idea why.

Is it possible the throttle is reversed and engaging the "prime" feature on ECU start-up? Are you using Futaba?

Hello all.

Xicoy had used two wire for pump and battery that are so close in color. It was why I couldn't identify whether it was pink, or orange, since put them
all in a bundle, its really difficult to distinguish between them two. I switch them around, and the problem is now fixed. I thank you all for your help.
