The oil rings and injectors were replaced together with a new timing belt. At the same time, we replaced the main fuse box ( ours is Asian model and the box replaced was for US model), however, we did check after that all fuses are properly connected and sensors are in good shape.
Engine initially wont crank so I sent the unit to a ECU fix outfit in UK and they ran codes out and found that ECU is indeed in good working condition.
However, we still cant start the engine, it cranks with good sound, fuel gets to injector but just wont fire up. We have checked the crank sensor and it is working.
Please help with professional opinion! Many Thanks!

if the fuse box is a asian model it needs an Asian model to replace it because the hookups or connections may or are probably different from the u.s. model.

Thanks for the reply hmac300!

We have ensured that all connectors , hookups are done correctly. It is something to do with the firing and we checked the distribution cap and firing order for the spark plugs, it will crank but will not fire up. What could be other causes?

check the routing of the fuse box as it's different for different things. I'd bet that the wiring is not hooked up correctly I the fuse box not allowing it to fire. I would check that prior to do any other checks. Have you tried putting the old fuse box in and seeing if it willfire? if it does then therein lies your problem.you can check crank and cam sensors for resistance if they are high it may not work but not set a code. I have no figures on those though. Also have your ignition module checked.
