    so i just got this 00 LS and the guy i bought it from swap the engine for a gsr, now the problem is that he left the p75 computer in it. and the vtec is not wired either. So i went off and bought a p72 obd2b and plugged it in but the engine wont start. Any ideas? i know that the 00-01 tegs have some kind of immobilizer or something like that. but i dont understand why the car wont start. I tried my friends p28 with the jumper harness and the engine runs a lot better than with the ls computer.

    has anyone done this swap before? HELP PLZ

    k what year is the motor if the motor is obd1 you will need the harness and a obd1 ecu thats what it sounds like i think the jumper harness is like 80 dollars and thats gonna solve your problem and you will need a new ecu man

    Hmmmm interesting, yes they have immobilizers in the key which affects the ECU but I think it should still start, did you get the ECU from a reliable source???
