5sfe replacement swap, cranks but no ignition., st204 gettting a new 5sfe put in Options

[W8NKER]

Unable to get the car to crank over to a start after completing the swap
I'll try give some infomation as to what the situation is,

The donor engine was from a 1998 st204 in perfect working condition (130ks) put into a 1995 st204 i have purchased
with a completely seized motor from driving at extreme heat after burst radiator.
Both engine bays/ecu's etcs are almost identical not much i can tell is different from the manufacturing years.

After the swap was complete the starter just continuously cranks, I have ALMOST got the engine to turn over a few time previously
by spraying a lot of aerostart while giving it some slight throttle acceleration but to no avail.

since last night i have tried a few things;

-checking all fuses
-making sure all accessible plugs are not loose
-tried using the 1998 ecu (cranks the same, appears identical)
-putting axles back on and topping up tranny oil
-checked grounds
-topping up fuel

Everything appears to be installed as its suppose to be as i have checked for anything loose
multiple times and compared engine bays.

I've already run out of ideas as i am new to this and hoping others with more experience could
give me some advise how to troubleshoot and diagnose what the problems is.

Seems to be something very minor but i just cant think as to what the problem could be.

cheers in advance for any advice

You're a little confusing. You say it's not cranking in the title but you then say it is cranking.

When you swap emissions specs you need to reuse all the manifolds and distributor sensors injectors and wiring from the old to the new.

yes, the distributors are different. it might be looking for the crank sensor in the dizzy and your engine has it on the crank
