i plugged everything back in and still nothing, but I'm getting a clicking sound from the engine bay when i turn the key to the on (II) position. now earlier today i pulled my ecu out and put in a obd2 ecu (the only one i could come across at the time) and it wouldn't prime my fuel pump either. now i understand that that ecu could also be bad since the age is up there on the part.

What OBD2 ECU? It would have to be OBD2b and plugged into the OBD2b ECU connectors.

it was a p2e ecu out of a 2000 civic and i just unplugged my jumper and plugged in my plugs to the ecu.

No i have not, i can see if my friends buddy with a swapped hatch can put my p06 in his car and see if it works for him.

If the P06 works in your buddy's car, then one of your test results is incorrect.

i will ne putting my p06 ecu into my friends car here shortly. I just wanted to post because i noticed that when i have my p06 plugged in and i turn the key to the on (II) position i have a clicking sound coming from the iacv and also a relay in the fuse box thats under the hood. Now when i plug in the p2e ecu that i got and turn the key to the on (II) position there is no clicking sound from the engine bay at all. Not sure if maybe thats a sign of something while my p06 is plugged in or not but figured it would be worth saying something about.

I got the problem fixed, it was the ecu. i plugged in a friends ecu into my car and it rand the pump. when i put my ecu into his car his car did not run, so the ecu i picked up yesterday was bad as well. Thank you ron j for all the help i greatly appreciate it.

What if the pump does not run, would that indicate a bad relay?

Possible, check for power at the pump, if no power. Pull and bench test the relay.
Check for power and continuity at the relay connections as well to verify power ON with the ignition in II/On.

Relay check out, power at the pump, continuity at the relay harness, all wires get the relevant power when ign is ON, relay checks out as per Honda's test for continuity outlined in the manual, but for the life of me when the relay is plugged in, nothing goes to the relay.
I wired up another 4 pin relay, using schematics from another user, which negates the start switch and ground wires, and i get power to the pump, but still cant start

So i got through, after all, turns out the ecu wasn't connected properly to have the pump come on, the reason for no start was the dizzy coil. Guys, lil advice, be sure to check for spark from the coil n don't just check for power at the coil, it may have power but no spark, ask me how i know.
