engine swap, ignition coil problems

[Cirus_93TSI]

so one of my friends found a 90 eclipse gsx(build date feb 90) for a good price, owner was an old guy who had never done any mods of anything to the car. i believe he was the original owner, car is bone stock and anything that has ever broken was replaced with OEM parts from the dealer and documented. had a small 16g turbo, that the man said the dealership recomended he get instead of another 14b when his went bad. the car ran before we pulled the engine, on all cylinders, but smoked far too bad to be driven.
so we decided to throw the engine out of my old car into it, which was a 91 tsi awd(build date dec 90) and the engine was a JDM longblock that i put in my car a few months before someone slammed into the rear quarter panel totaling my 91 due to body damage costing more then the cars blue book value.

now onto the problem. we swapped the JDM engine into the 90, and everything is exactly the way it should be as far as we can tell, but the car wolnt run properly. it will start, but only runs on 2 cylinders for a very short period of time and smells of fresh unburnt gas, and shows code 44: ignition coil.
we have tried the coil from the 90(that worked just fine before we pulled the engine) as well as the coil from the 91 we got the engine out of(which also ran just fine, before it was hit in the rear and sat undriven for 6 months), we have tried multiple ECUs, and multile cam sensors(the one on the end of camshaft) because the plug on the sensors was different on the 2 engines, but nothing seems to affect the problem. we tried everything in the haynes manual the the dealer service manual and everything seems to check out ok.

we were out of ideas, somy friend towed the 90 to extreme motorsports and let them take a look at it. car sat there for about 4 days, and then they called and told him they tried multiple ECUs, cam sensoer, igntion coils, ect, ect and cant find the problem. basicaly charged him 4 hours of labor, and made absolutely no progress on the car, giving it back to us exactly as it was when we gave it to them.

if anyone has any ideas on what the problem could be, id really like to hear them. we are completly out of ideas, the pulgs seem to be sparking and 2 cylinders will fire, but all 4 wolnt, and the code doesnt go away. we checked everything the 2 manuals said would cause that code to be thrown, and nothing solves the problem.
is there some difference between a 90 and 91 im overlooking thats keeping this car from running? or something that im forgeting to check that could be causing it? is the wiring in the engine bay any diff between the 2 years? we have the harness for everything in the engine bay from both cars, took the other one out but im not sure which one is on the 90 now.

Here's someone else who did 90-91 swap which may provide enlightenment: http://www.dsmtuners.com/forums/showthread.php?t=190429&highlight=differences

If you have a 91 motor and electricals.. like the link shows what i did you have to use ALLL 90 coil, transistor, CAS, and ECU... if not you can rewire it like the ecanfix link in my thread i started..

thanks for the replys, although im pretty sure we used everything off the 90. we used the 90 coil, intake manufold, and put the 90 CAS on it, and im pretty sure we used the transistor out of the 90 as well, and it still doesnt run.
im gonna print out everything off those links, and check over it again when i next get a chance, and see if we can figure it out. ill post results after we get a chance to do that.

we got the car running fine, thanks alot for the link and the help. we converted it to a 91+ ecu, used the 91 coil and power transister and it runs just fine now.

only thing that gets me, is how extreme motorsports had the car for 3 days and didnt have a clue what the problem was, even though my friend specificaly explained what year the car and engine were and what the problem was, to 3 people, 2 of which being the ones who actually know their stuff.
