Check Power Train Faults

[vzcalais89]

Just needing some feedback.

Took the car to an Auto Electrician as the Check Power Train is flashing, the car is running very rough, has a great big rumble. They sent me to a mechanic.

Got 3 code.

P0354 - Coil (they replaced coil but there was no change)
P0204 - Cylinder 4 Injector
P1638 - Fuel Disable ECU fault (they had no idea what this was, never seen before)

They then referred me to Holden for further diagnosis. I am able to find information about the cylinder injector fault but nothing really on P1638..... has anybody on here ever had this issue?

If i remember correctly, P1638 is disabling the fuel injector that is faulting, saving it from pumping fuel into the cylinder which it cannot burn, i may be wrong about this.

Bump very old post but having the same problem did you end up finding the issue?
