Fiat stilo 1.6
DTC P0230 and U1706 engine doesn't start, help?
P0230 Fuel pump relay problem
Security failure and loose connection error
Anybody can help?
I have removed A side connector from ECU
And test with phase meter, negative on phase meter to battery minus, and other side of phase meter to ECU cable B connector to some of pins and fuel pump works and fuel relay works also.
Does problem came from ECU?
