car stalling after starting - all help appreciated!

[John Linkan]

hi guys
i am having troubles with my v6 ve commodore.
i recently took it into a mechanic for him to have a look at it, as it is having a lot of troubles after replacing the engine in it.
after replacing the engine, it would crank but not start, so i replaced the fuel pump and module, and now it is starting but stalling a few seconds after starting.
the mechanic has done fuel checks, air checks, scans, and all inspections he can without taking the engine apart and he is totally stumped as to what it could be. no fault codes. fuel is pumping fine. air is fine. coils and spark is fine.
is there anything he may have missed? or any advice that could possibly help?

Thanks in advance all
hoping to get it fixed asap.

Possible air leak, is it stalling straight away or running for a bit then stalling, does it stall when you put it in gear? It could even been your torque converter stalling the engine

from what i’ve seen it usually stalls a few seconds after starting. will double check the things you mentioned!!

Unplug the cam sensors and see if it runs

What can you tell by doing that?

There are different ve v6 engines they have different cam sensors and cam phases, if you disconnect them and it runs you have the wrong cam sensors and cam phases or you have the cam sensors plugged in wrong and that's why it's stalling

Pretty sure both the LY7 and LE0 use the same part number for all cam solenoids and same part number for cam sensors.

They can be swapped about when fault finding.
