Icon5 Need Help h23a1 swapped Cb7

Hello all, i recently traded for a 92 accord with a h23a1 swap and im kinda stummped right now. im getting no spark and no fuel and a solid CEL even when trying to pull codes. the swap seems kinda done poorly but my goal is to just get it running. the Ecu in it is a pt3 and to my knowledge is the stock cb7 ecu and from what i researched i need a p14 ecu out of the prelude. would that be the reason im not getting spark or fuel or does this seem like a main relay issue because im also being told it could be that?

A thorough, logical approach will be key. get a copy of the PGM-FI wiring diagram. It's a good idea to start checking things at the main relay. check for the constant and switched voltages and chase down whatever is missing until you find the problem.

if electrical troubleshooting isn't your forte, grab a copy of the factory service manual. it's got clear step by step instructions for troubleshooting.

found a pgmfi fuse blown replaced that and it runs now, now im having an issue with the passenger side lights not working. all i have working is my driver turn signals, driver and 3rd brake light, and driver highbeam. everything on the passenger side doesnt even work or nothing. replaced the headlight fuses and and no avail. i can hear the relay click when i use the headlight switch so im assuming its a bad ground?
