Hey guys, finally, after a month of messing around, waiting for wiring, mounts, etc, the swap was finished and my rb25det was ready to be started! After a few minutes of cranking, nothing. ECU is throwing code 21 or 12, 2 slow pulses and 1 fast. Ive been searching for the last hour and a half all over the net for a service manual. If anyone knows this code or has the r33 rb25 fsm that would be awesome, thanks in advance!

P.S. Ive got spark and fuel, thought it might have been timing but not getting the 55 code.

Yah every link I tried was dead. Thanks alot 240sxed, turns out my ignitor chip wasnt grounded properly, so i fixed that, and the ecu returned code 55. But it still wouldnt start. Turns out I had the fuel lines in the engine bay reversed. I had them hooked to the rail and regulator properly but had stuck the fuel filter on the return line in the chassy. Stupid. Sorted that out and it fired right up. Now ive got to get my bodywork finished and and my exhaust work done and she'll be on the road. Thanks for the help.
