Could be a few things:

do you have standard coil packs fitted? or aftermarket?

are you using the s1 computer or s2 computer?

ignitor could be f#%&ed

Take the Cam Angle Sensor off, leave it connected to the loom and slowly turn the gear around, listen for the injectors clicking away happily, or not so happily. If they are opening and closing, take a plug out, and leave in in it's coil pack, rest it on the block so you can see the gap, and turn the lights out and slowly turn the CAS gear over, you should see a spark, be careful tho, that can give you a belt if you are holding onto it while rotating the CAS.

Both of the above require the igniton on, tell us how you go.

If you're attempting to use the S1 loom/computer with the S2 coil packs, the ignitor setup is all different.

Ignitor on S1 is the item that sits up the back.

On the S2 it is built into each coil pack.

could be cas or timing

What loom are you using S1 or S2?

Going through the same thing but i havent put the engine in yet though, im using S1 loom, S1 coils and igniter but im going to see the result with S2 TPS and CAS, if i have to get these too or not.

im also thinking you've mixed up s1 and s2 ignition parts. either use s1 coil packs and ignitor pack or just the s2 coil packs (not sure if you need to use the s2 ecu if you're using the s2 coil packs though).

ive installed a s2 engine using all of my s1 accessories - works perfectly fine. the only issue you'll have with the s2 throttle body is the loom plug - you'll have to check if the s1 fits as it has 2 plugs coming off the TPS. the series 1 and 2 CAS's are interchangeable.

ecu's are the same when it comes to coilpacks
