ka24de swap not starting

[i83fish]

Hi everybody,
I am just finishing my swap and I'm stumped. Can't find anybody else with the same problem as I do, any help would be much appreciated.

I have a 1990 s13 that I bought with a ka24E with a massive rod knock.
My brother gave me a RUNNING 1993 ka24de since he was going SR20det.

here is some info...
-1990 s13 body
-1993 ka24de engine and transmission
-original 1993 ka24de ECU
-upper harness is from a ka24de (unkown year)
-lower harness is from the original 1990 ka24e
-the 5th position switch doesn't have a corresponding plug on trans
-disconnected the PAIR valve and blocked off appropriate vac lines under throttle body
-getting spark in every cylinder
-getting fuel, I can see/smell it on the spark plugs
-the engine was running well before it was taken out
-there are several ground wires that the ka24de body has that my 1990 body does not
-dremelled my grounds, nice and clean
-I can smell gas in my exhaust pipe and standing over my engine after cranking it
-since the car had been sitting around for around a year, I drained the 8 gallons of gas in the car and put in 3 gallons of fresh 95 octane gasoline

Thank you for reading,
