VE Wont Start Or Crank

[GiggityPcs]

Hi guys i need help..

Earlier this week i started my 2007 VE omega and it ran find and after about 5 mins it shut off and has not started since then... it wont crank or anything when key is turned it just powers off radio ect (like normal) and does literally nothing... cluster says contact dealer .. i swapped out battery and starter motor so far and still nothing.. checked all fuses ect ...

any help is much appreciated as im srsly considering sending it to scrap

Possibly ECM failure. Need to get a scan tool and see if you can communicate with the ECM. If not check power and ground to it and if they are OK generally the module is cooked.

Does ENG light illuminate when in the IGN pos?

Does it have full battery voltage at the post on the front of the engine bay fuse box?

 

[GiggityPcs]

Yep

Any codes?

Nahh cant get anything from ecm .. sxanners dont even connect to it

If you can't communicate with either ECM I'd say the first is cooked and the second wasn't programmed correctly or is also cooked.

On the ECM connector X2, pin 56 should have battery voltage, if not check fuse 10 15AMP in the engine bay fusebox.

Also check that relays 13 MAIN and 14 IGN MAIN along with fuses 28 15AMP and 39 10AMP are all good.

The grounds on the same connector X2 should be pins 1,2 and 4.
