Error code 43

[Stigapex]

Hello

I've just installed the MCX 290 kit in my Apex XTX 2011. First time I started it, everything was fine, but then I hadn't installed the dash.

When I installed the dash, and then started it, it returned an error code 43, fuel system voltage, and the pump didn't run, and of course the engine stopped.
Error code 43 symptom says" The ECU is unable to monitor the battery voltage (an open circuit in the line to the ECU)"

I haven't picked off the intercooler yet. I thought I asked here first ?
Someone have any idea what the problem could be ?

Did you unplug the voltage regulator up in the nose? Is it plugged in fully?

I found the problem, it was the fuse. Maybe the MCX pump use a little more power, so I added a 15 A, instead of the 10 A
