You're using a VTEC ecu on a non-VTEC swap. That's one of your issues.

I'm not 100% sure it's a p28 it has no markings on it is there a way to find out on the inside and what ECU should I be running?

p06 will work for testing purposes, but will need a chip eventually. check and verify mechanical and ignition timing.

So I figured it out a local shop I brought it to to have tires put on and change the throttle body plugged the tps to the map and map to tps runs good now but still don't know what ECU is in it

Another thing is that I try and start it and all lights turn on but no clicking or anything so I have to jump it what can this be

To knw you have vtec or nt.. If you see this on ur head you probably have vtec..

Vtec solenoid

And erm a if u find ur ecu are using a Obd2a to Obd1 converter.. And the ecu look like this.. Then it a p28

P28 ecu

​​​​​I am not professional but.. Do u try to adjust the rpm idle at throttle body?

Likely the clutch switch pad is broken/missing.
