I have a 97 prelude i have bypassed the immobilizer switch, which then I was able to get a crank but no start, I have changed the distributor, ignition coil, spark plugs and wires, replaced starter, and replaced the crank sensor, main relay, fuel pump and it still won't start.
I'm getting a P1660 A/T FI data line failure. Can anyone help?

 

Sounds like your immobilizer is still interfering. As a test, you might consider using an OBD-2 -> OBD-1 conversion harness and an OBD-1 ECU... and if it starts, then you know what you have to do.
