Vs keeps stalling

[Waltap]

Hey I was wondering if anybody could tell me why my vs is stalling after I fire it up. I drove it around all day yesterday then on the way home it cut out on me and has been doing so ever since, I have recently replaced the fuel pump which has been in for about a week now and also the fuel filter, a few people told me I need to change the crank sensor, or even the ecu!! Help is much appreciated....

there is a plug near the coil pack , make sure it is making good contact otherwise it maybe the crank angle sensor, I wouldn't go changing the ecu without it first being tested.
you should retrieve the fault codes e.g. yourself or go to a mechanic or auto elec.

As above - check for fault codes which is very simple and you can do in 5 minutes with a paperclip. https://forums.justcommodores.com.au/threads/checking-error-codes-vr-vs-revised.22307

Now it's only stalling when I select a gear (auto) it idles fine but then when I select reverse it drops it's revs and starts to stall. The same thing happens to drive aswell. !!

I checked the computer and it said code 12 means all good. Does this mean it's a mechanical problem like my auto being rooted?
