specs: 2000 SI with obd1 gsr swap.

bought a obd2b p72 ecu, plugged it up, car will sound like its going to start but no luck. put the stock P2T ecu back in and started fine. ideas? TIA

 

Immobilizer maybe.

 

Do your self a favor and kill 2 birds with one stone, get a obd2 to obd1 conversion harness & a chipped obd1 ecu.

Kendall is correct. The 00-01 integra ecu's have a built in immobilizer

 

its the JDM GSR ecu, no immobilizer. whats wierd is when i take out of his SI and put it in my ek with y8, it starts but dies immediately
