just changed fuel pump last week and do a test run on the weekend.
not fuel pump up when I was drving in highway. then wont start any more.
1.Starter not clicking,
2.pump with out pressure (Fuel gauge zero) .
3,OBD2 not data.
4. fuel have no problem
5. DccD locked and flashing
6. sport mode locked
7. bettary no problem
8. test mode not working
9. recheck fuel pump, everything is fine.

I checked in some forum, found someone same as me. case happen after fuel pump changed. but did not found out any solution. Could any one please let me know if I got a faulty ECU? or my ECU been locked.
If locked did any one know how can I unlock it?

did you reset the ecu by pulling your battery for a few minutes ?

if still the same and it does nothing when trying to start with the lights flashing you may have a bricked ecu ... so search for sh boot mode

anyway I don't understand how this could happen only by changing fuel pump...did you reflashed the car ?

do you have any DTCs ? or no communication whatsoever with the ecu ?

This is a long shot, but I had a similar issue (not fuel pump related, just happened whilst driving).

There is a fuse specifically related to the O2 sensor that's not in the main fuse box (somewhere on the other side under the dash I believe), that if it blows, basically shuts the car down. You have power, the dash lights up, but starter doesn't click, right? And no OBD data / connecting to the ecu?

Let me see if I can find out exactly what the location of the fuse was, I'll let you know tomorrow. Incidentally, mine's also an 08/09.

FYI, the The 'extra' fuse box is directly above the passengers feet, below the cubby hole.

I have this same issue. Did a shboot, twice and still nothing, the car doesn't start. Maybe that fuse? Hope you read this !!

I figured it out, I installed a AEM Map Sensor, the ECU was in protection mode. I disconnected the map, and everything is back!
