Son's 81 came home behind a tow truck yesterday. From his description, it's a fuel problem (started missing, stumbled to a halt, no start).

I jumped the pumps at the fuse box - both run, tank draws 1.4A, main draws 5.5A, which sounds about right. Opened up the relay and there are obvious bad solder joints. My hamfisted attempt to resolder didn't result in a start. And there was no fuel pump 2-second-prime noise at 'key on'. (I think it's supposed to do this?)

Digging in my PnP treasure box I found a 6-pin relay with the same pin numbers as the relay in the car. But the one in the car is Red and has the Volvo logo and these numbers: 89 6369, and below that, 1 323 152. The hopeful replacement is Green, and has just this number: 89 81 60. Also: "Made in Hungary".

Looking at FCPGroton's web catalog, they state "Fuel Pump Relay GREEN in color 78-82 w/ K-jetronic...".

The car is a CA-spec B21F with the O2 sensor system and frequency valve, if that helps. Anyone know if this GREEN relay is a proper replacement?

Thanks, all.
