Default Mk3 caddy 1.9 BLS to ASZ engine conversion

I recently converted the van from BLS to ASZ
I swapped the camshaft hub, done the mod on block for the crankshaft sensor, swapped- turbo, injectors, egr, egr cooler, vacuum pump, I left the ASZ oil housing in as the BLS wouldn’t fit.
I fitted new filters and belts,
The car wiill crank but not start,
Just wondering if I have missed anything, thanks..

Is the fuel primed? Any DTCs? Timing correct?

Yes fuel is primed, timings correct and the DTC was G40 cam position sensor so I replaced it with my BLS camshaft hub and sensor as I forgot to do this but still no luck!

There is also a strange bleeping sound when you turn off ignition up behind the ECU and iv noticed there Seems to be a load on the battery (big spark) when you put connection on

Hi do I need to change pulleys to BLS crank and cam? I have BLS cam hub on but it is not lining up with 3Z or 4z marks
