OK guys gunna start off by saying I've been doing a lot of googleing and haven't found a answer yet I swapped out my old jade for a new rebuilt one hooked every thing up turns over will not start Im getting spark fuel and air it has hellah compression checked and reset timing replaced the dizzy 3 times and set it to tdc every time aswell changed plugs wires cap rotor redid all grounds swapped ECUs and injectors and it still won't start any ideas??? This is mind boggling I need my 40 back asap any help would be appreciated...

If you are getting fuel, spark, and air as you say, then it should run.
Has to be an issue with a timing/firing order mix up, or a sensor somewhere is playing up/not connected properly.
Is there any chance that you damaged some of the engine bay wiring during the swap?
Is there an immobiliser fitted to the car that could be the cause?

I'm thinking it might be either a wiring issue or timeing isn't on point 100% thanks for the input
