fuel pump/swap problem

ok i have a 93 integra gsr chassis with a 90 ls motor converted to obd 1 runinng a pr4 manual ecu, imusing the automatic wiring harness, however leaving the auto connectors alone,iwas told this works as long as ihave a manual ecu, BUT heres the problem, after the swap, when i turn my key, the fuel pump doesnt work, the fuel relay was tested, and works, when we bypass the relay, the pump works, could my ecu be bad ? i need to get this running thanks!

pr4 is OBDO not obdII the P75 is OBDII. Why don't you use a manual harness? I am sure that would fix the problem.

no pr4 is obd o and 1, and i dont need obd2, however, the harness we used works fine, and i know someone who used it and had no problems, so its not that
