Hi, I have the vehicle listed above ve ss z series commodore with the code P069E. Have replaced the fuel pump and fuel pump module, the car cranks but won't start just wondering if anyone knows anything about what could possibly be the problem. Thanks.

The P069E code indicates a problem with the fuel pump or its control module but since you replaced those already the problem will be in the wiring, or you have a blown fuse. I would start by checking the fuse "FSCM" 20 amp which is in the rear fuse panel and the IGN EGN FSCM fuse in the fuse panel under the hood.

There is also a fuel pump control relay I would swap out as well which is in the fuse panel under the hood as well. Please check these out and get back to me, here is a guide to check the wiring and the fuel pump system wiring diagrams so you can see how the system works and which wires to test.

Also, what are your thoughts? After I changed the fuel pump the car went for 4 days perfectly fine then wouldn't start when back to cranking then a week later it started again after using the spare key but only turned car on then it wouldn't turn back on then another week later bought a new battery for the key and car started straight away drove it around for half an hour then tried to start it again after 4 hours then went back to cranking. Do you think it might be the battery? When you turn the key with the scan tool attached to the car the battery voltage keeps dropping from 12v?

Hello,

Have you checked the connector at the fuel pump for possible burnt pin 2?
See image below.

This seems to be a common problem. A replacement harness will need to be fitted if you find an issue.

Cheers, Boris
