ECU Tuning & Fuel Management - code 5

Hey everyone i just completed an engine swap and the car wont start, i noticed that it was throwing a code 5 which is my map sensor, i swaped a d15b jdm motor in my 95 ex, have no idea what to do next, can anyone help.

i dont think that a map sensor code would keep it from running. it would just go into limp mode. also try checking if you have spark, fuel and that the engine is firing on number 1 cyl at the right time. thats just the basics, but also it could be somthing with the ecu right? anyone else?

i need the correct firing order and a diagram lol it is getting spark and fuel..
