Does anyone know how far up the wiring harness does pin 1 of the PGM-FI relay go before it gets routed back to A16 of the PCM?

I seems I have an open connection on this line.

I have a 2000 Honda Coupe

 

HX, EX, Si, DX?

 

It is an EX

Thanks in advance

 

Have you tested the wire for an open using a multimeter or are you guessing?

The Grn/Yel wire runs directly from C443 to C452.

 

Yes tested with an ohm meter open from A16 to pin 1 on the PGM-FI relay.

Should be a straight shot but I do not know how far the Pin 1 side goes
up into the harness before it routes back to A16.

 

You're overcomplicating a simple problem. Depin the Grn/Yel wire at the main relay connector and at ECU connector A. Cut the connector pins from the broken wire. Resolder a new wire to the removed pins. Plug pins back into the connectors. Enjoy driving your car that now runs. Easy, inexpensive fix.

 

Sorry for late post. Thanks Ron Definitely Fixed my problem
